Sunday's 60 Minutes investigates why the Australian Border Force is failing at stopping people smuggling.

Broken Borders
No one disputes that patrolling Australia's extensive sea borders is a difficult job. But it shouldn't be impossible. Off the north-west coasts of Western Australia and the Northern Territory, the task of stopping people trying to enter the country illegally is primarily the responsibility of the Australian Border Force. But in this joint 60 Minutes, The Sydney Morning Herald and The Age investigation, Nick McKenzie reports how broken our borders have become because the ABF is failing. The organisation's equipment is sub-standard, at times even dangerous; a fact that has severely impacted its operations. And as a consequence, the people smugglers have again been plying their evil trade.

Unfathomable
If there's one small comfort to be taken from the OceanGate deep-sea submersible disaster, it's that death was instant for the five occupants on board. But a year on from the tragedy, there are still so many unanswered questions. Most fundamentally, why did the strange-looking craft on a mission to the wreck of the Titanic fail so spectacularly? And why, for days on end, was the world wrongly led to believe there was hope for a successful rescue mission? The lack of credible information about what really happened is now becoming increasingly unfathomable, not only for the families of the victims, but also for other undersea explorers like legendary Hollywood director James Cameron. Speaking exclusively to Amelia Adams, Cameron reveals that this is a catastrophe that could and should have been avoided.

On 60 Minutes, Adam Hegarty speaks to Boeing whistle-blowers while Dimity Clancey investigates painkillers known as nitazenes.

High Alert
Few Australians have probably ever heard of Nitazenes, but soon it's likely that everyone will know all about them. Not for good reasons though. Nitazenes are extremely potent painkillers which can be as much as a thousand times stronger than morphine. They were developed in the 1950s, then quickly deemed far too dangerous for humans and so were largely forgotten. But now these synthetic opioids have reappeared and are being produced in massive quantities in Chinese laboratories. As Dimity Clancey reports in this special 60 Minutes investigation, nitazenes are being shipped to western countries including Australia, where they are hidden in all types of illicit drugs, ready to cause harm – and often death – to unsuspecting users.

Corporate Crash
Not so long ago, many airline passengers used to swear by the saying: "If it's not Boeing, I'm not going." It was a motto the company loved. But in the last six years, two fatal B737 MAX crashes, as well as multiple other incidents, have meant drastically changing times for Boeing. Now, the slogan is the complete opposite: "If it's Boeing, I'm not going." On Tuesday, the plane maker's humiliation was plain for the world to see when its boss was forced to appear before angry U.S. Senators in Washington. CEO Dave Calhoun was grilled about his company's plague of deadly safety and manufacturing issues. On 60 Minutes, Adam Hegarty speaks to Boeing whistle-blowers who reveal disturbing allegations about shoddy practices and cover-ups. For anyone who flies, it seems the turbulence for Boeing is far from over.
