Four Corners

The Liberal Party is hurtling towards a reckoning. This isn't just a battle that will decide who leads the Liberal Party; it's a battle for the party's identity, and direction. Patricia Karvelas takes you inside the contest that will shape the future of the Coalition.

Four Corners' "Scarred" reported by Louise Milligan and produced by Mary Fallon looks at practices by one of Melbourne's most prominent gynaecologists.

He was a top Melbourne surgeon who women trusted with their bodies and their futures.

But he removed organs and tissue from women in their twenties for what he told them was severe endometriosis, while failing to tell them that their pathology showed little or no signs of the disease. His procedures compromised their fertility and left some with chronic, debilitating pain.

This week, Four Corners uncovers how this was allowed to happen and why no one intervened until it was too late.

Reporter Louise Milligan and the team uncover how one of Melbourne's most prominent gynaecologists carried out repeated laparoscopic surgeries that senior specialists describe as unnecessary and harmful.

This seven-month investigation draws on patient testimony, forensic examination of medical records, and doctors speaking out for the first time. It exposes a pattern of surgery that experts have told Four Corners went far beyond accepted practice.

It also exposes how complaints, warnings and red flags were ignored.

This is a story about medical power, institutional failure and the devastating consequences when accountability breaks down.

It raises urgent questions about what must change to prevent it from happening again.

"Toxic Tide" reported by Angus Grigg for Monday's Four Corners is produced by Alex McDonald and looks into South Australia's algal bloom.

It's one of the worst environmental disasters to strike Australia's waters. Expected to be over in weeks, a year on, the South Australian algal bloom continues to devastate parts of the coastline.

As South Australians go to the polls this weekend, Four Corners investigates what the government knew about the health risks and what they told the public.

Despite the toxic bloom decimating marine life, shutting down parts of the fishing industry and according to some people, leaving them sick, the government repeatedly downplayed the health effects.

Angus Grigg and the Four Corners team piece together what the government was told and its public messaging.

Toxic Tide raises urgent questions about transparency, trust, and accountability in times of crisis. It serves as a warning for the rest of Australia about how governments respond and communicate as climate-driven environmental disasters become more frequent and more severe.
