Consultation has now closed on proposed amendments to the development of the former Australian Defence Industries land at St Marys.

The Sydney Regional Environmental Plan No 30—St Marys is a planning instrument that has guided the development of the ADI site at St Marys since 2001. It provides key provisions such as zones, development controls and the requirement for the adoption of precinct plans prepared by Penrith and Blacktown city councils.


The proposed amendments are outlined in the Explanation of intended effect (pdf, 653kb) and mainly relate to land identified as the Central Precinct and Regional Park.


They are:

  • rezoning of approximately 38.4 ha of land within the Central Precinct from Employment to Urban. This is expected to create approximately 500 additional lots for housing.
  • revising the size and location of land zoned Drainage to reflect the stormwater management strategy for the site
  • rezoning of approximately 1.2 ha of land within Jordan Springs in the western precinct from Urban to Regional Park that is currently identified for use as Local Open Space.


Also see the Maps and Resources tabs for supporting details.


Feedback on the proposed amendments to SREP 30 St Marys was open from 4 April to 11 May.
