Australia is a country celebrated for its wildlife, yet native species are in crisis. In the last 200 years, Australia has lost more biodiversity than any other developed nation.

In this book, award-winning science writer Justine E. Hausheer encounters pygmy possums that live high in the Snowy Mountains, hears the booming calls of bitterns from their adopted home in the Riverina’s rice fields, crouches after dark in the spinifex grasslands listening for the elusive night parrot and meets adorable fat-tailed dunnarts who might hold the answers to reviving the Tasmanian tiger. The Vanishing Wild immerses us in the harsh reality of the extinction crisis – and shows us the future of conservation and what can be done to save Australia’s native species.

In this episode Gregory Dobbs chats to Justine Haushseer about the ever-growing list of endangered species from the iconic koala to the little known pygmy blue tongue lizard, the ethical challenges of de-extinction technologies and... what exactly are the Cane Toad Olympics?

After suffering a loss, Janine and her husband, Kamal, need a fresh start. They leave their family and everything they know in Manchester and move to Bamblethorpe, a picturesque Lancashire village where they expect nothing but peace and quiet. It’ll be just what Janine, a thriller writer, needs to work on her next manuscript.

But the peace of their new village life is disrupted when longtime local Alexa Clarke goes missing. Did she leave her husband, like some people suspect? Or is there credibility to the rumours that something more nefarious has happened to Alexa?

Frozen by writer’s block, Janine stumbles into investigating Alexa’s disappearance, and the more she discovers about Alexa’s life, the more complicated things become. Nothing is as it seems, and Janine begins to realise that there are disturbing parallels between Alexa’s life and her own. What starts as curious procrastination quickly spirals into a tangled web of secrets, lies and a truth Janine may not be ready to face … if she survives.

In this episode Gregory Dobbs chats to Jess Kitching about the accidental merging of genres in her writing, how a tree change to a quiet English village comes with hidden dangers, and how grief and loss changes lives.

For Amy, being a doctor was supposed to mean winning at life. Helping people. Saving lives. Having a secure job. Earning good money. Tick, tick, tick, tick. But now, in her second year in a city hospital the reality is a world away from Amy's med school dreams. She is finding out that people don't always want to be 'helped', the pay barely covers rent, her hours are ridiculous, her favourite patients are getting sicker, and her surgical trainee boyfriend has recently gone shy on proposing.

What Amy does have are the friendships forged by dealing with recalcitrant patients, endless nightshifts, and crying in the emergency department bathrooms. And a belief that maybe, underneath it all, it's a job that's still worth doing.

In this episode Gregory Dobbs chats to Kerry Jewell about giving the reader the complete hospital/medical training experience, why the idea of being a doctor isn't necessarily the reality, and how cynicism, sarcasm and black humour are all part of the job.

Three first responders – a paramedic, a police officer and a firefighter – are motivated by a desire to serve the community. But they are drawn to their work by more complicated impulses as well: a need for control, an acute awareness of danger, and childhood experiences they are still running from.

Peter, a paramedic, served at high-profile disasters including the Port Arthur massacre and the Beaconsfield mine collapse. Despite helping countless people, he is haunted by the lives he couldn't save.

Tara, a firefighter, experienced devastating loss at a young age. She found camaraderie in the fire brigade, but also confronting reminders of her past.

Brett, a police officer, survived childhood neglect and abuse. Policing offered a way to impose order, but it eventually forced him to question his rigid moral view of the world.

In telling their stories, Martin McKenzie-Murray draws on his own experience and his research into trauma and recovery to ask profound questions about human motivation and survival. What draws people to these intense professions, and how does their work reshape them? And what happens when their carefully built walls between past and present, personal and professional, start to crumble?

In this episode Gregory Dobbs chats to Martin McKenzie-Murray about why we need know about the experiences of first responders, why it is a vocation and not just a job, and reasons for the reluctance to seek treatment for the PTSD that many first responders suffer from.

Peter Marralwanga (1916–1987) was a leading figure in one of the great art practices of the world. He grew up in western Arnhem Land surrounded by artists painting in rock shelters and he learned to paint this way himself. The subjects of his paintings were the Djang who made his country and placed the spirits of people within it. Marralwanga’s story highlights the way bark painting became important as a way of evading assimilation policies rife within Northern Territory towns. Marralwanga established an outstation at Marrkolidjban where he could teach his children how to properly care for Ancestral lands, with part of this care involving a knowledge of how to paint. As a senior person who had travelled widely in his youth, and gained extensive ceremonial knowledge, Marralwanga was highly influential among a broad group of painters. Ivan Namirrkki, a painter of note and Peter Marralwanga’s son, has provided here his own account of his father’s life.

This book tracks Marralwanga’s life of learning about country and conveys the religious meaning of numerous major works, offering outsiders a richer understanding and appreciation of Arnhem Land art. It also shows the crucial role of individuals working for the community arts cooperative Maningrida Arts and Culture in facilitating Marralwanga’s rise to recognition as a major Australian and world artist.

In this episode Gregory Dobbs chats to Luke Taylor about the tradition of Aboriginal bark painting that Peter Marralwanga drew from, the depth of knowledge of Aboriginal culture and ceremony that he brought to his paintings, and the political dimension to Marralwanga's work and its role in the developing land rights movement of the 1960s and 70s in Australia.

In Raven Mother, Jane Messer weaves together her Jewish family’s tragic story – stretching back and forth between Berlin, Israel, Palestine, Melbourne and Sydney. Messer retraces the steps of her Jewish grandmother Bella, as she tries to understand her life in pre-war Berlin and Mandate Palestine, to post-war Melbourne where she didn’t survive the surviving, and why her father was abandoned in England before the war. In this powerful, beautifully written and insightful book, Messer spends time in Berlin, Israel and Palestine and grapples with the effects of nationalism, both historical and contemporary. Along the way, she speaks with historians, activists, refugees and scholars, and constantly to her beloved father.

In this episode Gregory Dobbs chats to Jane Messer about the origins of the old German term, 'Rabenmutter', the city of Berlin under the Weimar Republic and the Third Reich, and what she discovered about her grandmother Bella along the way.

Theresa Miller has spent decades working as a journalist and now media trainer, coaching people across all industries – from CEOs and academics to climate campaigners, entrepreneurs and artists – to communicate confidently, clearly and concisely. In Speak Up, she shows you how to successfully share your expertise and experience with an audience – whether it’s creating an inspiring work presentation or media release, blitzing a job interview or nailing your message on a podcast, panel, TV or radio interview.

In this episode Gregory Dobbs chats to Theresa Miller about why the demand for public speaking is bigger than ever, why being an expert in your field is not enough to get your message across, and why preparation and presentation skills are fundamental to good communication.

In 1986 on Phillip Island, a young woman called Beth Barnard was savagely murdered and her boyfriend’s wife, Vivienne Cameron, went missing. The police immediately jumped to what they thought was the obvious conclusion: in a jealous rage, Vivienne had killed Beth and then herself. Vivienne’s body was never found.

But Vikki Petraitis wasn’t convinced. The official line didn’t explain all the evidence, and it certainly didn’t seem like the behaviour of a mother with two small boys. Fascinated by both the case and the bias it revealed in investigators, Petraitis wrote her first true-crime book about the murder, with Paul Daley, and decades later made a podcast on the case. Both brought new evidence and testimony to light, and asked questions that were not asked at the time.

To mark the fortieth anniversary of Beth’s murder and Vivienne’s vanishing, Petraitis brings together all her discoveries and true-crime experience in a brilliant forensic investigation into what happened all those years ago, and why.

In this episode Gregory Dobbs chats to Vikki Petraitis about why she has returned to this forty-year-old cold case, about her insights into the Philip island community, and why she is not convinced that the police investigation had reached a reasonable conclusion.
