Tim Costello

In 2008, Costello received an honorary doctorate from the Australian Catholic University in recognition of "his contributions to religious life and social justice".

From 2004 to 2016, Costello was CEO of World Vision Australia, where his remuneration in 2012 was $258,718 AUD). He received the Victorian of the Year award in July 2004 in recognition of his public and community service. He was made an officer of the Order of Australia in June 2005 and was the Victorian nominee for the Australian of the Year award in 2006. He is the 2008 winner of the Australian Peace Prize awarded by the Peace Organisation of Australia. He is also listed by the National Trust as a "National Living Treasure".

Costello served as the president of the Baptist Union of Australia from 1999 to 2002. He has also been patron of Baptist World Aid Australia, a member of the Australian Earth Charter Committee, a council member of the Australian Centre for Christianity and Culture, a spokesperson for the Interchurch Gambling Taskforce, a member of the National Advisory Body on Gambling and a member of the Alcohol Education and Rehabilitation Foundation.

Costello was an elected delegate at the Australian Constitutional Convention in Canberra in February 1998. Throughout the late 1990s and early 2000s, he was frequently seen in the Australian national media commenting on gambling and other social problems. He also has spoken out in favour of stronger gun control in Australia, acting at times as the co-chairman or spokesman of the National Coalition for Gun Control.

From 1995 to 2003, Costello was a minister of the Collins Street Baptist Church and the executive director of Urban Seed, a Christian not-for-profit organisation created in response to concern about homelessness, drug abuse and the marginalisation of the city's street people.

Costello was elected Mayor of St Kilda Council in 1993 and became well known for championing the cause of local democracy and for his clashes with the Premier of Victoria, Jeff Kennett. Kennett attacked Costello as being un-Victorian for speaking out against the gaming-led recovery of the state and often referred to him as "that leftist cleric". Costello's political career ended when his mayoral position was abolished with the whole St Kilda Council in Kennett's reform and consolidation of local government in 1994. Towards the end of that time, he was approached by the Australian Democrats political party to fill a casual vacancy in the Senate, but decided against it, partly due to the likelihood that this could place him in direct conflict with his brother if Peter became Treasurer.

Ordained as a Baptist minister in 1987, Costello, along with his wife Merridie and a team of others, rebuilt the congregation at the St Kilda Baptist Church and opened a drop-in centre. As part of the church's outreach program, he started a legal office at the church where he practised as a part-time solicitor. He also taught urban ministry at Whitley College, a college of the University of Melbourne.

In 1981, Costello travelled to Switzerland with his wife, Merridie, where they both studied theology at the International Baptist Seminary Rueschlikon near Zurich, before graduating with a Bachelor of Divinity and returning to Australia to become the minister of St Kilda Baptist Church. He also received a Master of Theology from Whitley College, a theological college of the Melbourne College of Divinity.

Costello studied at Monash University, graduating with a Bachelor of Jurisprudence degree in 1976, a Bachelor of Laws in 1978 and a Diploma of Education in 1979.

Timothy Ewen "Tim" Costello AO (born 4 March 1955) is an Australian Baptist minister and the current Chief Advocate of World Vision Australia. Costello is the brother of Peter Costello, the former treasurer of Australia and Federal Member for Higgins.

Costello was born in Melbourne, Victoria, where he grew up in the suburb of Blackburn and was educated at Carey Baptist Grammar School. He is a descendant of Irish immigrant Patrick Costello, who was expelled from the Parliament of Victoria in the 1860s for electoral fraud.
