Leigh’s 40-year career in broadcast journalism stretched over more than a generation of breathtaking change in communication. He started as a radio journalist at 2GB in Sydney and worked in the Canberra press gallery for radio, then television between 1975-1976 and 1981-1983. He was Seven Network’s European correspondent and Chief Olympic correspondent, reporting on the Atlanta and Sydney Olympic Games.

For 13 years he was one of the senior presenters at Sky news, through the emergence of what became known as the 24-hour news cycle.

His conversation with Tim Argall begins on the steps of Parliament House, Canberra.

Lisa has written seven best-selling books – and three duds, as she cheerfully admits - and is an internationally known speaker at schools, conferences and business events. She grew up in a family of tennis professionals, surrounded by high achievers from all over the world. At 26, Lisa set her own goal: to positively affect the lives of one million Australian teenagers. It was a goal that was to change her life. For the next eight years, Lisa travelled the country speaking in schools and to youth groups. Parents of those young people, also inspired by what they heard, invited Lisa to speak in their places of business, establishing her as an inspirational corporate speaker. She’s the only person outside North America to be inducted into the International Speakers Hall of Fame.

Lisa was born with her left eye closed, went through many surgical procedures in her early years and, unsurprisingly, was often cruelly teased throughout her schooldays. Her conversation with Tim Argall begins in Year 12.

The Right Reverend Stuart Robinson was born to unmarried musicians in Kings Cross, Sydney. Adopted and brought up by devout Christians, he’s been involved in church planting, growing Christians not churches, heard shattering stories of child abuse while Bishop of Canberra and Goulburn, and is now Rector of South Head Anglican Church in Sydney. He met his birth mother when he was 30 and his paternal grandfather not long after. They’ve remained in contact ever since. In this podcast Stuart shares what he's learnt about personal healing, being a leader and faith through the dark times.

Natasha is a Senior Research Fellow at the Centre for Public Christianity. Her conversation with Tim ranges through misunderstanding, entrenched positions and pessimism in public discourse before resolving in the truth that all are made in the image of God – which means we have to learn to speak with people who hold different views.

Natasha has a PhD in English Literature from the University of Cambridge, has two published books to her name, and writes regularly on topics that include books, movies, politics, food, domestic violence, Scripture in schools, war, Thanksgiving, and freedom of speech.

Sam is renowned for his energy and passion for evangelism to a sceptical world. A qualified and experienced doctor with a PhD in Theology, he now works with the City Bible Forum, speaking to school and college students, to professionals and academics alike on evangelism, ethics, preaching and story-telling.

He also blogs as the Espresso Theologian, which he describes as a short, quick, buzz of theology - taking you from your world to Jesus in 60 seconds.

In this podcast Sam reminisces about rugby – especially getting concussed – tells how surgeons manage to operate on the correct leg and why the second question, “And how are you REALLY going?” is the key to a real conversation about Jesus.

When Joseph was a child in Uganda, anyone in his village with a bicycle was considered middle-class, and the one with a car was unimaginably wealthy. Today Joseph works with World Vision in East Africa, where he is responsible for humanitarian and disaster relief across nine countries and millions of dollars in aid funds. In this podcast Joseph describes how he first wanted to work against poverty, how he became a Christian, and how an Anglican bishop gave him his first job despite being told that “you’re a Pentecostal!”

Lisa lived the high life working in the travel industry until a trip to South Africa in 2004 changed her perspective for ever. As she wept over the pain and poverty she'd seen, God took her from a work culture of hedonism to a work culture of humility and service, as the founder of Mission Travel, and then into Selah Tours - designed to give Christians time to pause in the lands of the Bible. But 2020 gave Lisa a different kind of pause -  time to reorder loves and destroy idols, from which she's emerged with a deeper, stronger faith in a God who loves without measure.
