The vision for the Growth Centres - as part of the Metropolitan Strategy for Sydney - was launched by the NSW Government in December 2004. Since then, the Department of Planning has taken the lead on the two major stages, being:
- The exhibition of the draft Growth Centre Plans, from June to October 2005.
- The exhibition of the draft State Environmental Planning Policy 2005 - Growth Centres, which closed on 10 March 2006.
Leppington is not within the first stage of the release program. Therefore all planning matters will continue to be managed by the Council and there is no change to the existing land use rights.
