Tim Costello
Chief Advocate

As Chief Advocate for World Vision Australia, Tim Costello continues to place social justice and global poverty on the national agenda. Serving as Chief Executive of World Vision Australia for the 13 years (2003-2016), Tim helped to bring positive change to the lives of the world’s most vulnerable and disempowered. His commitment to alleviating the suffering of communities in poverty became evident in 2004 when the Boxing Day Tsunami struck. His leadership during this period helped inspire and foster the unprecedented generosity that the Australian public showed, in which $100 million was raised in relief funds. Tim has also positioned World Vision to be a major responder to those displaced by the conflict in Syria. He currently also serves as Chair of the Community Council of Australia.
