Hillsong Church is a charismatic Christian megachurch and a Christian association of churches based in Australia. The original church was established in Baulkham Hills, New South Wales, as Hills Christian Life Centre by Brian Houston and his wife, Bobbie Houston, in 1983. Hillsong was a member of the Australian Christian Churches – the Australian branch of the US-based Assemblies of God – until 2018, when it separated to form a new denomination.
