Behind the scenes | S6 host Dominique Bayens in conversation

What goes into making a season of Expanse? What considerations are made when telling the stories of people's lives? Host of Expanse: The Nannup Four, Dominique Bayens, sits down with fellow podcast host Phil Vine to take you behind the curtain.

It has been months in the making, but police are opening up the files on the missing Nannup Four for Expanse host Dominique Bayens, and there's news on another search. 

Since the podcast started rolling out, a lot of people have got in touch with information. Two people have been able to shed light on some previously unknown parts of the story. 

A family friend and former policeman continues to search for answers for Jim and Cath McDougall decades after the Nannup four vanished. The family and friends of Chantelle McDougall try to find their own answers, as one last glimmer of hope emerges. 

Jim and Cath McDougall are left reeling as the true depth of Simon Kadwill’s deception is revealed. Dominique tracks down people from his past, and hears from someone who has never spoken before who provides a startling insight into how Simon might have ended up on the path he did.   

Tony Popic is talking about an end of days, Simon is seeing spirits and Chantelle is forced into a difficult decision as increasingly troubling hints something's not right come to light. 

Dominique travels across the country to meet the two people who might be able to help her understand how Chantelle came to be living a reclusive life in a hidden corner of Western Australia, alongside a self-styled spiritual guru 18 years her senior.   

A chance encounter in the streets of Melbourne in 1998 leaves a friend wondering what Chantelle McDougall has been pulled into. Dominique hears about the escalating pattern of control Simon Kadwill exercises over Chantelle.If you can add to this story, or have information you think might be important, please get in touch by emailing [email protected] this episode, we cover topics like:Chantelle McDougall and her daughter 5-year-old Leela vanished from Nannup, Western Australia in 2007, while entwined in the "Truth Fellowship" cult.Who are the missing people who disappeared into this cult?The baffling mystery of a cult Nannup family of four who disappeared in 2007.
