For more than 80 years, the Australian War Memorial has stood as a solemn shrine to those who have served and sacrificed for our country.  

This week, Four Corners reveals how this sacred institution is increasingly entwined with the global arms industry — raising troubling questions about conflicts of interest, corporate influence, and the future of the memorial itself. 

In Sacrifice, Gold Walkley Award-winning journalist Mark Willacy exposes how the war memorial has accepted funding from some of the world's largest weapons manufacturers, despite former insiders condemning the money as "dirty" and inappropriate for an institution dedicated to honouring the human cost of war.

As the war memorial undergoes a $550 million redevelopment — described by critics as an attempt to turn the site into a "Disneyland of war" — this investigation asks whether the expansion ensures the memorial's future or undermines its fundamental purpose.  

The Yoorrook Justice Commission is making history as Australia's first formal truth-telling inquiry, shedding light on a violent past long buried in the nation's consciousness. 

Bridget Brennan, with the ABC's Indigenous Affairs Team in collaboration with Four Corners, has been documenting the powerful testimonies presented to the groundbreaking commission in Victoria, which expose the deep and ongoing impact of massacres and human rights abuses which began when Australia was colonised. 

Among these stories is the harrowing account of the Warrigal Creek massacre, where, in 1843, dozens of Aboriginal people were shot dead by white settlers in retaliation for the killing of a pastoralist's nephew. 

For Elizabeth Balderstone, the tragic history of Warrigal Creek is not just a historical account - it is a lived reality. She and Gunaikurnai elder Uncle Russell Mullett have come forward to share their story, bringing long-suppressed truths onto the public record.  

"If we are to have a future where we live together with understanding," Uncle Russell said, "we must first be willing to know our history—and accept it." 

The documentary witnesses the gruelling and deeply personal work of the Aboriginal truth commissioners, as they attempt to document the true history of Victoria. 

The team also follows along as the Commission investigates the catastrophic legacy of a former Prime Minister. 

Truth/Yoorrook is a fearless, definitive documentary which examines how we as a nation reckon with our colonial past and take critical steps towards truth, healing and justice.
