Hedley Thomas started his career as a copy boy at 17 and spent four decades chasing some of the world's biggest stories, from the fall of the Berlin Wall to the Hong Kong handover, before finding his most powerful tool yet: the podcast.
In this episode of The Missing Matter, Sally sits down with the award-winning investigative journalist and creator of The Teacher's Pet to explore how long-form audio storytelling has reshaped the fight for justice in cold cases and missing persons investigations.
From reporting on the Dawson case in a Brisbane newspaper library in 2001 to producing a podcast that helped send Chris Dawson to prison, Hedley explains how the freedom of podcasting allows him to go where traditional media can't, unpacking briefs of evidence, finding new witnesses, and keeping cases alive long after the system has moved on.
With more than a hundred million downloads and investigations that have driven real-world change, Hedley reflects on what keeps him going, why he believes the criminal justice system has failed victims, and why the missing still matter even when the guilty think they've gotten away with it.

Former police officer turned investigator Graeme Crowley has spent nearly fifty years chasing justice.
What began as a career in policing eventually evolved into something unexpected, true-crime podcast investigations that challenge official narratives and reopen forgotten cases.
In this episode of The Missing Matter, Sally sits down with Graeme to explore how podcasting has become a powerful tool for uncovering new evidence, questioning flawed investigations, and giving families answers when the system has failed them.
From missing persons to suspicious suicides and wrongful convictions, Graeme explains how pulling apart a brief of evidence can reveal cracks in the story prosecutors once relied on.
He shares how one podcast investigation helped push police to re-examine a suspicious death ultimately leading to a murder arrest that may never have happened otherwise.
Together, Sally and Graeme discuss:
Why missing person cases often lose urgency within the system

The hidden problems inside coronial investigations

The emotional toll on families waiting decades for answers

How podcasts are changing the landscape of criminal investigations

For Graeme, this work isn’t a job — it’s a lifelong pursuit.
Because sometimes the search for truth doesn’t begin with police.
And sometimes the answers come from the people who refuse to stop asking questions.
