Four Corners is Australia's premier television current affairs program. It has been part of the Australian story since August 1961, exposing scandals, triggering inquiries, firing debate, confronting taboos and interpreting fads, trends and sub-cultures. Its consistently high standards of journalism and film-making have earned international recognition and an array of Walkleys, Logies and other national awards.

A Deathly Silence attempts to break the taboo of silence that surrounds the act of suicide, its illusory appeal to the vulnerable, and its cruel toll on the living.

Clinicians now believe that modern strains of super-strength cannabis are increasingly triggering psychoses, depression and anxiety disorders in teenagers. Many young people begin smoking cannabis before they have even hit their teens and experts are warning that the younger the smoker, the greater the risk of mental illness. Recent research shows that the human brain does not fully develop until a person reaches their twenties. Teenage brains, therefore, are more vulnerable than adults to cannabis. Modern technology multiplies the dangers. Hydroponically grown, genetically modified varieties of marijuana plants are believed to contain much greater concentrations of the chemical THC, or tetrahydrocannabinol. Cannabis is cheap, too, making it more easily available to today's teenagers than it was for their parents' generation. Young cannabis users in treatment for psychoses speak openly about their experiences to reporter Janine Cohen, while doctors and drug specialists explain what the new research means for young people's mental health.

A businessman in Papua New Guinea is accused of taking millions of dollars for government work that has never been completed. He is charged but released on bail. Then, using an Australian issued 457 Visa, he comes to this country and avoids justice, telling authorities he is too sick to travel back to PNG. Crime fighters in Papua New Guinea say this type of behaviour is all too common.

Labor's leader Kevin Rudd, dispatched three years ago by his own party, was returned to take up where he left off as Prime Minister of Australia. By any measure it's a desperate move by a party facing, as the new Prime Minister said, an electoral catastrophe. For the past four weeks, Four Corners has been tracking Labor's painful decision to restore Kevin Rudd as leader, the mounting fear within the party of electoral wipe-out, the ambitious last acts of Julia Gillard's minority government and the gamble for Labor's future with a leader it rejected more than once.

Would you allow your child to use a gun to hunt and kill animals? Across Australia there are thousands of families who not only let it happen, they encourage it. Hunting is now a growth sport and the reasons are simple. For many it's exciting, selling guns is a lucrative business and hunters have new-found political muscle. Many hunters say they do it to get back to nature and to source fresh meat. While they put ethics and safety first, it's the rogue hunter that is the problem.

Australians love sport and they love to gamble. Put the two together and there's lots of money to be made. Across the globe sports betting is dominated by huge, faceless corporations with deep pockets, all looking for market share. By contrast in Australia, the industry might be growing but it certainly isn't faceless and for that it can thank one man. His name is Tom Waterhouse. Son of a bookmaker and top line horse trainer, he's made himself the face of sports betting in Australia. Taking out advertising slots on the Nine Network, he was also given a place on the network's rugby league commentary team. It was the boldest move yet by an industry that's taking every opportunity to grab publicity.

There is not a person in the community that is not affected by cancer in some way. Next on Four Corners, we go inside the hospitals and consulting rooms with Australians who are confronting the reality that the advanced cancer they have could kill them. The question is, how much time have they left and what can their doctors do to buy them more time?

He's not exactly the Kiwi Bond. He failed to bring home the America's Cup, but he's pulled off deals in New Zealand that would make Alan Bond swoon. These have been testing times for yachting tycoons, but when Alan Bond ran aground in a Perth court last week at least it was hailed as a boost for Australia's battered reputation in the international marketplace. When Michael Fay foundered off San Diego last month, it was a major set-back for New Zealand. If the high-flying merchant banker had won the America's Cup his backers in the New Zealand government thought the whole nation would reap a dividend. It would have been a fitting return for all that New Zealand has given Michael Fay and his elite circle of business friends. Like the good sailor he is Sir Michael knows how to make the most of prevailing conditions, even on dry land, and few places are as dry right now as the New Zealand economic landscape. As hardship and unemployment surge in the face of this social experiment, the Fay phenomenon is attracting growing resentment.

The Reserve Bank of Australia is meant to maintain stability in the nation's financial sector. It is supposed to be above reproach in its behaviour. But is it? Why did bank-appointed officials and employees break sanctions in Iraq and cosy up to Saddam Hussein through a "front man"? Why did a former Deputy Governor and other directors hand-picked by the Reserve Bank to safeguard its subsidiary companies from corruption, end up--over a decade--overseeing some of the most corruption-prone business practices possible? Why did they allow millions of dollars to be wired to third parties in foreign countries, including an arms dealer, in order to win banknote contracts in deals police now allege involved bribery and corruption?

We know the problem. More Australians are fat and they're getting fatter. What no one can agree on is how to stop an epidemic that's threatening to make the next generation less healthy than the one before. Everyone agrees that one part of the answer is to exercise more. What's less clear is how people can be encouraged to eat a healthier diet. On one side, public health advocates say food companies must reduce the levels of fat, salt and sugar they put in their products. On the other side, many believe diet is a personal responsibility way beyond Government regulation.

Australian casinos that target Asian VIP gamblers to boost their profits could run a serious risk of exposure to organised crime, according to a range of law enforcement and security experts. This week on Four Corners, reporter Linton Besser investigates the drive to entice foreign gamblers to Australia and the implications of that strategy.

It took just one phone call from a Thai journalist to expose the plight of 'Baby Gammy' and to send shockwaves through the Thai surrogacy industry. But it wasn't just people in Thailand who felt the impact. Some Australians found themselves with newborn babies that they couldn't take home. This week, Four Corners reporter Debbie Whitmont is there as one of these families tries desperately to find a way out of the situation. As she tells the story of this couple and their twins, she also takes us inside an industry that has grown with little effective regulation, leaving it exposed to unscrupulous agents.

While Australians argue about when or whether to confront global warming, the top of the globe is melting away. The Arctic sea ice sprawled across an area roughly the size of Australia - is in retreat. Scientists now fear that in less than 25 years from now, for the first time in human existence, there will be no sea ice in the North Pole in parts of the summer.

Is public health falling victim to private profit in the race for a biotech bonanza? Every day, worldwide, laboratories routinely analyse human genes to pinpoint a whole range of suspected diseases. Life-saving treatment can depend on fast, accurate diagnoses. Four Corners spotlights one Australian company, a hot item on the stock market, which is aggressively enforcing a suite of patents that affect an extraordinary 95 per cent of every living creature's DNA.

Insiders turned outcasts speak candidly and emotionally to Four Corners about the Exclusive Brethren practice of family separation. Life inside the secretive and puritanical Exclusive Brethren sect and the heart-rending price extracted from those who leave. They've launched controversial forays into election campaigns in Australia, New Zealand the United States. Now the Exclusive Brethren are drawing more unwanted headlines, this time accused of trawling for dirt on the sex life of the New Zealand Prime Minister refers a low profile and forbids its flock from voting. But paradoxes abound in the Exclusive Brethren.

When was the last time you had a good night's sleep? Are you one of the million-plus Australians who spend their nights watching the minutes tick by, dreading the morning, knowing you'll be exhausted? Some say it feels like dragging a piano around, an awful deadening weight. So why are so many of us unable to sleep? For one in 20 Australians, sleep is no longer a given, it's a luxury.

With more and more Australians living longer the task of finding quality care for people who can't look after themselves is getting tougher. The Federal Government says that Australia has a first rate system which looks after its most senior citizens, but is that really the case? Reporter Wendy Carlisle talks to four families about their struggle to find quality care for their loved ones.

Children across Australia talk about the alarming impact of bullying on their lives. Despite major efforts from governments, schools and teachers, bullying remains an intractable problem made worse by modern technology. Once it was fists, rocks and personal abuse - now bullies have the net, mobile phones and Facebook as their playgrounds for brutality. This isn't just concerning - it can be lethal, as reporter Quentin McDermott reveals.

An unflinching portrait of Australia's remote Indigenous communities and their struggle to survive. Prime Minister Tony Abbott recently provoked furious debate by describing life in these communities as a "lifestyle choice" and the Commonwealth has withdrawn its funding. Communities in Western Australia are now facing possible closure, provoking protests around the country. But this Four Corners report confronts the uncomfortable truth about life in these communities. The Four Corners team travelled across the rugged Kimberley region of Western Australia to visit some of the settlements under threat. In some, they found grinding poverty, no jobs and little hope. In others they were told of appalling stories of sexual abuse and neglect. But they also found community leaders determined to tackle the dysfunction.

Marian Wilkinson examines the campaign being waged against the Federal Government over climate change policy that will put a price on Australia's greenhouse gas emissions for the first time.

Right now there are over 4,000 people held in immigration detention centres across Australia. On average, asylum seekers remain in detention for around a year, but that figure hides a group of people who remain locked away for much longer periods of time. Just over a year ago, the Federal Government announced it would begin releasing children into the community to minimise the harm caused by their incarceration. At the same time, thousands of adults remain locked away in detention centres remote from the rest of the world - a situation that's concerning to many healthcare professionals.

Antibiotics are the wonder drugs of modern medicine. They've allowed doctors to save and extend life by killing infection and enabling ground breaking surgery. But imagine a world where antibiotics don't work?

Slaving away: The dirty secrets behind Australia's fresh food. It's in your fridge and on your table: the fresh food that we take for granted. But there's a dirty secret behind it. Much of it is picked and packed by a hidden army of migrant workers who are ruthlessly exploited. A Four Corners investigation has uncovered gangs of black market workers run by unscrupulous labour hire contractors operating on farms and in factories around the country. The produce they supply ends up in our major supermarkets and fast food chains. These labour hire contractors prey upon highly vulnerable young foreigners, many with very limited English, who have come to Australia with dreams of working in a fair country. They're subjected to brutal working hours, degrading living conditions and the massive underpayment of wages. Reporter Caro Meldrum-Hanna has obtained undercover footage and on-camera accounts of this dark world.

Australians love a bargain, but what's the real cost of cheap clothes from the sweat shops in Bangladesh? On 24th April this year more than a thousand people were killed when an eight story building collapsed in the heart of Bangladesh's capital, Dhaka.

Rehab Inc: The high price parents pay to get their kids off ice. Across Australia, there are parents risking everything to rescue their children from ice addiction. To end this living nightmare, they'll seize on any chance to get help for their child. But that chance of rehabilitation can come at an enormous cost. Publicly funded rehabilitation beds are in short supply and have waiting lists running into months. So instead, these families turn to private clinics. And they charge a fortune. Parents are risking bankruptcy to get their child a place. They're encouraged to access their superannuation or to re-mortgage their homes in order to pay out tens of thousands of dollars to ensure their child gets in quickly. And the price is driven by demand, rather than the service provided. And the lack of regulation is shocking. Even some private operators concede families risk being ripped off.

Backing Bourke: An outback town's bold experiment to save its young people from a life of crime. This famous bush town has one of the worst crime rates in Australia. With startling rates of domestic violence, assault and property crime, too many of Bourke's residents end up in jail. Fed up with losing their young to prison, the indigenous people of Bourke have decided to take a risk on a bold experiment to try and turn their town around. It's based on a groundbreaking American approach called Justice Reinvestment that tries to prevent crime through simple targeted programs. It's been so successful that in places like Texas, the state has actually been closing prisons down. But can this same idea work in outback Australia? Backed by wealthy philanthropists, not government, the community is putting the theory to the test with practical ideas, like offering free driving lessons. It's diverting people from jail time as driving without a license is a chronic problem in the outback. And it's also trying to change attitudes, prompting the men of Bourke to take a long hard look at themselves and stand up as leaders. Two months after the landmark Four Corners program Australia's Shame exposed the scandalous treatment of juvenile offenders, Backing Bourke provides a glimmer of hope for communities around Australia that are struggling to break the cycle of youth crime.

China Rising: The challenges for Australia as China and the US struggle for supremacy in Asia. Reporter Peter Greste joins Four Corners for a special report on the rise of China and its escalating contest with the United States in the Asia Pacific region. In interviews with key players from the world of diplomacy and strategic affairs, the program explores how Australia is trying to balance two competing interests. Greste and a Four Corners team travelled to the South China Sea to investigate the rising tensions caused by China's rapid military expansion. As the standoff intensifies, the program examines the growing pressure on Australia to take sides.

For Better or Worse: How the personal has become political in the fight over same sex marriage. On the eve of the Labor vote which will determine whether the same sex marriage plebiscite goes ahead, Four Corners investigates the politics at work behind the debate. When the Abbott-led Coalition Government emerged from a marathon party room meeting last year to announce there would be a public vote on the legalisation of same sex marriage, it sparked a passionate debate. Some were suspicious. Since then, politicians of every political stripe have been deliberating over the legalisation of same sex marriage and the means by which that decision should be made. Four Corners has been charting the strategy employed by each side, and has been given behind the scenes access to many of the key players in this debate as they make their case. Four Corners talks to them about the tactics they are employing, and asks how much of the discussion is about conviction and how much is about the art of politics.

The Forgotten Children: The young refugees stranded on Nauru. They're the human face of Australia's tough border policies - the more than 100 refugee children living on Nauru. Four Corners speaks to children and young people recognised as refugees, released from detention, but trapped in limbo. In footage filmed for Four Corners and smuggled out of the country, these children talk of their experiences over the last three years. Both the Nauruan and Australian governments say they want the refugees moved on from Nauru, but they have been unable to reach agreements on where else they could be sent. While that stalemate continues, many of these children are struggling to hang on to hope. Back in Australia, the experience of these refugees has had a lasting impact on the teachers who had to leave them behind.

These are Australia's most vulnerable kids, betrayed and neglected, not only by their parents but by the system designed to protect them. They're known as 'resi kids' after the group homes they live in, run by private operators and charities. Some were taken into care as babies, others after years of abuse. They're often difficult to manage but desperately in need of help. In this searing Four Corners investigation, we reveal that rather than protecting and nurturing these children, some private operators are treating them as badly as the families they escaped. It's prompted some in the child protection system to brand their treatment a national failure and call for the entire resi care system to be shut down. This investigation, nearly three months in the making, continues online in a special digital feature with further revelations of systemic failings.

Four Corners brings you the powerful story of one of its own, veteran reporter Liz Jackson, as she comes to terms with a devastating illness. For nearly 20 years, Liz Jackson reported from the frontlines of war and politics for Four Corners, winning nine Walkley awards for excellence in journalism, including the Gold Walkley in 2006 as well as three Logie Awards. But after she left the program in 2013, her health collapsed. She was losing her physical strength and her ability to write, and was suffering from crippling panic attacks. Liz was diagnosed with Parkinson's disease. Despite a barrage of medication, Liz continued to deteriorate. So with unflinching honesty, Liz Jackson has turned the camera on herself. She brings her fierce intellect and penetrating questioning to try and understand her illness - interrogating her doctors and comparing experiences with fellow patients. This moving film is a collaboration between Liz, her partner Martin Butler and his colleague Bentley Dean, both highly acclaimed film makers. This 55-minute special program, made in partnership with the ABC, Contact Films, Screen Australia and Film Victoria will also be available on ABC iview along with a selection of Liz Jackson's most memorable films.

Shark attacks are turning our beaches into places of fear. On the beaches around Ballina, on the north coast of NSW, that fear is palpable. With nine attacks, one of them fatal, in the last 12 months, people are asking why and demanding action. Four Corners investigates why these sudden spikes occur. Millions of dollars have been outlaid by State governments in NSW, Queensland and Western Australia on prevention and protection measures; but is it money well spent? Environmental activists point to the high price paid by other marine life in the quest to make the ocean safe. And there's intense debate over whether these anti-shark measures actually work.

It's the bank that's spent two years rebuilding its reputation after being exposed for ripping off its customers in a devastating financial advice scandal. The Commonwealth Bank is adamant that it's learned its lesson. Now, the reporter who broke open the financial advice scandal, Adele Ferguson is back, with another investigation into the Commonwealth Bank. Six months in the making, this joint Four Corners/Fairfax investigation focuses on the insurance arm of the bank, CommInsure. They're in the business of selling the kind of insurance policy you hope you never have to claim. Insurance to cover you or provide for your family if the worst should happen, like a serious health condition or death. But this investigation will reveal how CommInsure uses unscrupulous tactics to take consumers' money and avoid insurance payouts, leaving customers paying money for nothing at the most difficult moment of their lives.

"We can beat anyone, as long as we do whatever it takes" - Essendon Football Club Advertisement. As muscular sporting slogans go, it's a beauty. But for Essendon Football Club, it's become memorable for all the wrong reasons, symbolising the attitude that brought the Club undone. It was their motto as they prepared for the 2013 AFL season, just as the story of the Club's supplements program broke open, kicking off the biggest sports drug scandal in Australian history. Three years on, despite numerous reviews, investigations and court hearings, there are still questions the club has not answered. To this day, the players still don't know exactly what they were given. This week Four Corners takes you inside one former Essendon player's battle to find out just what was in the supplements he was directed to take. As a rookie with the club, Hal Hunter joined the other more senior players in the supplements program. He gives an eye witness account of what it was like to be part of the regime and what went on once the scandal broke. He describes how the Club has stonewalled his attempts to obtain his medical records prompting him to take action in court, the first Essendon player to do so. Hal Hunter's case gives an insight into the oversight of the club and its approach to the duty of care it owed all its players.

It's a story of intrigue, corruption and multiple murders, stretching from the streets of Malaysia's capital Kuala Lumpur, to Switzerland, France and the US as well as Hong Kong and Singapore, all the way to Australia's doorstep. The money involved is astonishing. And the escalating scandal is threatening to bring down Malaysia's Prime Minister. Four Corners reporter Linton Besser investigates two sets of extraordinary allegations of bribery and corruption: one involving a massive arms deal; the other, the Malaysian sovereign wealth fund. It's a story that's made headlines around the world. Linton Besser's pointed questions landed him and cameraman Louie Eroglu in serious trouble. Four Corners will reveal new allegations about the staggering sums of money that have flowed into the bank accounts of Najib Razak. And as the scandal grows, so does the crackdown on the Malaysian Government's political opponents.

It's the shadowy world of secret international finance and tax avoidance. This Four Corners investigation will reveal how the rich and powerful exploit the system. Reporter Marian Wilkinson follows the money trail and it's worth trillions of dollars. This story was produced in collaboration with Suddeutsche Zeitung and the International Consortium of Investigative Journalists.

Clive Palmer: the rise and fall of a business empire and political career. Four Corners charts the rise and fall of the mercurial Clive Palmer, examining how he made his money, friends and bitter enemies along the way. With Palmer's political influence plummeting and serious questions hanging over his companies, reporter Hayden Cooper talks to political players, former colleagues and the workers left sacked at the now closed Queensland Nickel refinery in Townsville. Many are speaking out for the first time.

The Australian Government contract to provide healthcare to detainees has already cost taxpayers more than a billion dollars, but doctors say the medical care provided offshore in Manus Island is dangerously inadequate. On Four Corners some of Australia's most senior doctors and medical staff with experience in the offshore detention system are speaking out. They say the Border Force Act could see them risk two years in jail for disclosing information about Australia's asylum seeker detention system. Despite this, the doctors have chosen to talk. Their story centres on the case of a Manus Island detainee, Hamid Khazaei, who died following a bacterial infection in 2014. What started as a skin infection poisoned his body, leaving him brain dead. The details of his rapid decline and the treatment he received are shocking. Doctors involved in his care are speaking publicly for the first time, giving a rare inside account of the medical treatment available in our offshore detention centres.

The body of a young woman lies on the beach. Two panic stricken men try to work out what to do. One makes a call to '000', the other goes and flags down help. But as people began arriving on the scene it became clear the men had serious questions to answer. The young woman had died of horrendous internal injuries. Five years on, what happened on that beach haunts everyone involved. Despite a thorough police investigation and a scathing Coronial Inquest recommending charges be laid, no one has ever faced court. In this searing story, Gold Walkley award-winning reporter Caro Meldrum-Hanna follows the trail of evidence, and finds a family that won't give up.

Money and Influence: the shadowy world of political donations. As we head into the third week of the election campaign, Four Corners investigates just how transparent the political parties really are when it comes to revealing who their donors are and what is expected in return. It's a world that operates far from public view with a patchwork of donation laws around the country. A variety of methods are used to keep the identities of donors secret, leaving voters hard pressed to find out just who is funding whom. Reporter Quentin McDermott, talks to influential figures operating in this world, who speak candidly about their experiences. And in an exclusive interview with Four Corners, the regulator withholding more than $4 million dollars of funding destined for the Liberal party breaks his silence.

"All our savings go to IVF…Then you get that negative pregnancy result. There's another $6,000 gone" - Grace. Grace is one of the tens of thousands of Australian women who have put their faith in fertility treatments to help conceive a much longed for baby. At 42, she's been through six unsuccessful rounds of IVF. The physical, emotional and financial toll is huge. Julia too, had dreams of becoming a mother, undergoing 8 rounds of fertility treatment. And while she willingly put her body in the hands of fertility specialists, she struggled to get a clear answer on just what her chances of having a baby actually were. Four Corners looks at the booming business of fertility, where the industry pulls in more than half a billion dollars in revenue, and asks whether clinics are giving women clear, unambiguous advice about their chances of giving birth. Many fertility specialists say it's up to individual women to decide how much treatment they can take. But as this program shows, there are concerns, even from industry insiders, that some women undergoing IVF don't actually need it. Others warn against the practice of upselling - where women are sold expensive and unproven treatments that one doctor says is akin to snake oil. And disturbingly, they also have concerns about the potential harm fertility treatments could be causing for women - including potential links to cancer.

Gold Walkley and Logie Award-winning reporter Sarah Ferguson interviews the two men vying to lead Australia. In this special episode of Four Corners, with the election only days away, Sarah Ferguson sits down to talk with Malcolm Turnbull and Bill Shorten as they make their final pitches to the voters.

Regardless of who wins the Federal election, the major issue facing Australians is the future of work. There are startling and credible predictions that more than five million Australian jobs will simply disappear in the next 15 years, as a result of technology. That's 40% of the jobs that exist in Australia today. What do you want to be when you grow up? Answering that question is only going to get harder as many of the jobs our kids will do haven't been invented yet. And if parents believe that steering their kids towards "safe" professions like accountancy will guarantee them a job, they're in for a shock. There will be winners and losers in some surprising areas as more and more jobs become automated or operated by intelligent computers. It's good news for baristas and personal trainers, but not for real estate agents. And the days of long haul truck drivers may be numbered. The loss of these jobs will be challenging for the existing workforce as there may simply not be enough jobs to go round. But the greater fear is that we're not preparing our kids for work in this technological age. Schools and universities are churning out students with qualifications for jobs that won't exist, instead of training them for the ones that will be created. We meet the kids giving up their weekends to learn the computer coding skills they say they're not being taught at school. And explore the schools who believe they're unlocking the future with innovative teaching methods and an emphasis on the so-called STEM skills, maths and science. Many are arguing that we must act now to change the way we educate our kids or risk them sleep walking into a world they won't be equipped for.

It almost defies belief but in Australia there is a prison system that locks up 10 year olds and places children as young as thirteen in solitary confinement. Children have been confined to an isolation wing with no access to sunlight or running water. Some held for weeks on end, deprived of basic necessities. Four Corners reveals the shocking truth about the treatment of children behind bars, where young offenders have been stripped naked, assaulted and tear gassed. Held by a system that seems bent on breaking children instead of reforming them.

Across Australia the number of police suffering from Post Traumatic Stress Disorder is growing, damaged by the extreme situations they're repeatedly exposed to. And untreated, they can be a danger not only to themselves but others. But when they put their hand up for help, many of these police officers are being subjected to humiliating and harmful practices employed by insurers. Claims for compensation and psychiatric treatment are being met with scepticism, resistance and lengthy delays. And insurers are going to extraordinary lengths to avoid payouts. Four Corners has spoken to police around the country who have been spied on, their privacy invaded on an astonishing scale, with both physical and electronic surveillance. For these police, the aggressive tactics exacerbate their mental illness, sometimes with awful consequences. And psychiatrists are calling on insurers to change their approach.

Man on a wire: How long can Malcolm Turnbull survive? On Four Corners, key members of the government speak out about the fault lines within the party and challenges facing Prime Minister Malcolm Turnbull. With the Coalition government returned to office on the slimmest of margins, the Prime Minister will not only have to woo and cajole a disparate group of cross benchers to vote for his policies, he'll have to hold his own team together. Within the party room resentment lingers over the controversial policies taken to the ballot box. There's barely contained anger from those who feel they've been marginalised by the Prime Minister: And there's factional warfare breaking out in the state branches. Adding to Malcolm Turnbull's woes is the question: what are Tony Abbott's intentions?

Milked Dry: The awful price being paid by Australian dairy farmers for the milk we drink. They're the farmers who get up at five in the morning, day in, day out, to provide milk for the dairy products we eat and drink every day. The shock decision by Australia's biggest dairy company, Murray Goulburn, to cut the price of milk paid to farmers has left many trapped in a nightmare of debt and despair. Four Corners visits the farms where it's costing farmers more to make the milk than they can get for selling it. The situation has become so desperate that some farmers are selling off their prized cows for slaughter, others are walking off their farms for good. Many of these farmers were already angry after the company locked them in to supply $1 supermarket milk. But that's nothing compared to the fury they feel now. Four Corners investigates the mismanagement that's led the dairy industry into such despair.

Cyber War: How hackers are threatening everything from your bank account to the nation's secrets. In a room, deep inside a Las Vegas hotel, the world's best hackers are gathering. They're here to compete against each other and they're being watched by cyber warfare agencies the world over, not for prosecution, but for recruitment. They have the skills needed to wage espionage and warfare in the modern age. Four Corners takes you into the world of cyber hacking, where the weapon of choice is computer code. Featuring an interview with the former head of the CIA and the NSA, Michael Hayden, he explains how the intelligence business has changed with young hackers parachuted into sensitive operational activities. We take you into the cutting edge facility where Australian soldiers are being trained in the arts of cyber warfare - where their computer skills can be used to shut down a power grid or cut off a city's water supply. And will reveal the strategic Australian companies and institutions that have found themselves hacked. It's not just nation states that are in the hacking business, it's also criminals, and as the program demonstrates, it's frighteningly easy to hack our lives. If you have a smart phone, if you use internet banking, if you store your information "in the cloud" then you are at risk.
