I Catch Killers with Gary Jubelin

In this continuation of their deep dive, Gary Jubelin speaks with former Western Australian police diver Luke McCulloch about the harrowing reality of underwater investigations. Luke details the psychological and physical demands of searching for evidence and recovering bodies in "deep, dark, and dirty" conditions—from murky riverbeds to the open ocean.
Luke shares the terrifying experience of working in shark-infested waters and explains why the "touch and feel" of a recovery operation never truly leaves you. They explore the professionalism required to operate in high-stakes environments and the emotional toll of a career spent finding what no one else wants to find.
In this episode:
The reality of body recovery in zero-visibility environments.
The dangers of diving with Great White sharks.
The intense selection process and resilience required to be a police diver.
The lifelong impact of "deep, dark, and dirty" operations.

Loved ones of missing people are desperate for answers, and unfortunately there are people more than happy to exploit their despair for their own gain.
In part two of her conversation with Gary Jubelin, missing persons advocate and author Nicole Morris calls out clairvoyants and psychics, exposing the very real trauma caused by false hope. The pair discuss why all missing persons should be treated as homicides until proven otherwise, how dangerous assumptions made early in an investigation can derail justice and leave families without answers for years, and call for better resourcing and a national approach to missing persons investigations.

Every single day, around 130 Australians on average are reported missing. For the families left behind, there are no funerals, no closure, and no answers, just an unbearable silence where a person used to be. Nicole Morris has spent over two decades refusing to let that silence win.
As the founder and director of the Australian Missing Persons Register, Nicole has supported countless families through the devastating trauma of unexplained disappearance. For more than two decades, she has earned the trust of law enforcement agencies and government bodies across Australia and internationally through her relentless commitment to ensuring the missing are never forgotten.
In this episode of I Catch Killers, Gary and Nicole break down the human cost of disappearance, what it truly means to live with an "ambiguous loss", and share the stories of families whose lives have been irrevocably changed by unanswered questions.
Gary and Nicole also take a hard look at the system. Why does the first response to a missing persons report matter so much? What goes wrong when cases aren't treated with urgency? And why does the dangerous myth that you must wait 24 hours before reporting someone missing continue to cost precious time?

Less than 10% of reported sexual assaults result in a conviction in Australia. So, what does it actually take to bring a rapist to justice? In part 2 of former police officer and survivor Caroline Clarke’s chat with Gary Jubelin, we find out exactly that.
In this episode, Caroline details the aftermath of being sexually assaulted by a massage therapist - from the agonising decision to report, to becoming an active force in her case recording a confession that police called "the best they’d ever heard".
Caroline also unpacks one of the most misunderstood reactions in trauma - the freeze response, a survival mechanism hardwired into all of us. Yet it still continues to be used against survivors in courtrooms, in conversations, and in their own heads. Caroline breaks down why it happens, how it works, and why the shame so many survivors carry about it is not only unfair, it's wrong.
