Tim Costello is one of Australia's most well-known and respected community leaders. In recent times he was voted one of Australia’s 100 national living treasures. A recipient of Victorian of the Year and Victoria's Australian of the Year accolades, as well as an Officer of the Order of Australia, he is an influential leader on a range of social issues, including the huge harm caused by the scourge of gambling in Australia.

Tim is a previous longtime CEO of World Vision Australia and has helped lead the response to some of the greatest humanitarian disasters of recent times, including the 2004 Indian Ocean earthquake and tsunami. A former Lawyer, Tim is a man with many hats. He’s the Director of Ethical Voice, Executive Director of Micah Australia, Chair of the Community Council of Australia, Senior Fellow for the Centre for Public Christianity, and Chief Advocate for the Alliance for Gambling Reform. He is also the Chief Advocate of the Thriving Communities Partnership and Patron of the National Youth Commission. He’s also the author of several books, including his excellent memoir, A Lot with a Little, which I highly recommend. I particularly enjoyed the section of that book that describes Tim and his wife Merridie’s journey in building a congregation at St Kilda Baptist Church and an accompanying drop-in centre and outreach program. It was from here that Tim’s advocacy grew and he later went on to become the Mayor of St Kilda, where he developed a reputation as an outspoken social and political voice for change, a voice that is very much a voice of love and courage.
