The Sydney Region Growth Centres biodiversity certification aims to protect some of the best remaining bushland in Western Sydney while providing the underlying biodiversity approvals for the delivery of much needed housing.

The Minister for the Environment proposes to extend the biodiversity certification of the State Environmental Planning Policy (Sydney Region Growth Centres) 2006. Under the repealed Threatened Species Conservation Act 1995, Part 7 of Schedule 7, clause 20, an extension of the biodiversity certification up to 2035 is proposed.

The certification is currently set to expire on 30 June 2026, following its previous one-year extension. This one-year extension allowed the Department of Climate Change, Energy, the Environment and Heritage to review the certification and ensure the certification can meet its remaining conservation obligations.

The public is invited to make submissions relating to the extension of the biodiversity certification. At the end of this consultation, the Minister will consider the feedback submitted in deciding whether to extend the certification and the period of extension.
