Description & Facts: Brian and Bobbie Houston moved from New Zealand in 1978 and joined the Sydney Christian Life Centre at Darlinghurst, pastored by Brian Houston's father, Frank Houston. They started Hillsong Church, which was then known as Hills Christian Life Centre, in August 1983 with services held at the Baulkham Hills Public School hall and with an initial congregation of 45. Within four years it had grown to 900 people. In 1990, the church moved from "the warehouse", which they had occupied since 1984, to hold services at the Hills Centre. In 1986, an annual conference was developed, now called Hillsong Conference, which was created to be a blessing to the church worldwide and to champion the cause of the local church. In the early 1990s, praise and worship recordings from the Hills Christian Life Centre were released in Australia and internationally under the name Hillsong. This raised the profile of the church. The name is also used for a television show featuring clips from the videos of the recordings and a message from Brian Houston. In 1997 the church moved into its new building at Baulkham Hills' Norwest Business Park. In the late 1990s the church realised that the name Hillsong was more well-known than Hills Christian Life Centre due to the branding of its recordings. The church was renamed Hillsong Church in 1999, about the same time its mother church, Sydney Christian Life Centre, was merged into Hillsong Church. After further consistent growth, a new 3,500 seat convention centre at the church's "Hills" campus was opened, on 19 October 2002, by John Howard, the then Prime Minister of Australia. Due to the rapid growth of the "City" campus, in 2007 the church announced its intentions to develop a significant area of land on Rothschild Avenue, Rosebery into the new "City" campus. In August 2008, Hillsong withdrew the development application they had lodged with the Sydney City Council after an independent report recommended against the council approving the development, and in August 2009 announced that the site was for sale. It has been reported that Hillsong is looking at other options for its City church plans, including buying the former Royal South Sydney Hospital site.
