1 Million Dollar Reward
In this final episode, Sally reflects on the emotional announcement that the reward for information into her mum Marion Barter’s disappearance has been increased to $1 million. After nearly three decades of searching, Sally travels to Sydney for the announcement at NSW Police Headquarters, speaks with Ben Fordham, and shares what this moment means for her family. She talks about the impact of Marion’s disappearance, the loss of her brother, the coronial findings, and the ongoing questions around the man identified as a person of significant interest. Sally also opens up about new information still being passed to police, her trip to Japan with Joni to search for records, the importance of correcting errors in missing persons profiles, and why families should be contacted with compassion when possible evidence is found. As the series comes to an end, Sally looks back on the journey, thanks those who have supported her, and explains why the search for Marion does not stop here. This is an episode about hope, grief, persistence, and the belief that someone, somewhere, still knows something.

The Power of the Podcast with Hedley Thomas from The Teacher's Pet
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.

The Justice Tragic: Graeme Crowley’s Fight for the Forgotten
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.

Bonus - Stephanie Tinsley - The Power of the Podcast
Sally's journey into searching for her mum has travelled the globe, and now so has The Missing Matter. In this episode of The Missing Matter, we travel to Nashville, Tennessee, to speak with Stephanie Tinsley, host of the investigative podcast Everything They Missed. Stephanie shares how witnessing the Alex Murdaugh murder case up close drew her into the world of true crime and exposed serious flaws in the justice system. That path led her to the 2007 murder of Danny Harris and the wrongful conviction of Andrew Hayes, a man who has spent 18 years in prison for a crime he says he didn’t commit. We talk about the power of podcasting to uncover missed evidence, the vital work of the Tennessee Innocence Project, and the emotional toll of chasing truth in real time when justice, freedom, and hope are still on the line.

Scott Matters.... Missing 199 days
In this episode, Sally speaks with Janette Hayden, whose 46-year-old son Scott vanished on 29 May 2025 near Taree, NSW. Scott’s behaviour had been shifting in the weeks before he disappeared—talking about God, training hard, eating clean, and struggling with his mental health. His family did what families do: they worried, they watched, and when things escalated, they went to police. More than once. Days later, Scott’s bright gold car was found abandoned with his wallet, keys, shoes, food and belongings still inside — but no sign of Scott. It has now been more than 199 days. Janette bravely walks us through the timeline: the changes in Scott’s behaviour, the alarming events of that night, the unanswered questions, the footprints found, the community efforts, and a police response that left the family feeling dismissed at the most critical moment. This is the story of a much-loved son, brother and uncle — a man who matters deeply to everyone who knows him. If you have information that may help find Scott Hayden, please contact Crime Stoppers or reach out privately via the Facebook page Can You Help Find Scott Hayden?
