Hillsong Church, with a congregation of over 14 000, is likely the largest church in Australia. Its main site is located in the northwest of Sydney, in Norwest Business Park (near Castle Hill, NSW), with a smaller site in the CBD. Established by Pastors Brian and Bobbie Houston, it is a member of the Assemblies of God congregation. A new 3500-seat convention centre at its main site was opened on October 19, 2002, by John Howard, Prime Minister of Australia.
