The program is achieving this by buying land for new reserves and securing funding agreements with landowners to permanently conserve their land. This land is being protected by the NSW Government to offset the impacts on biodiversity that will be caused by the development of the North West and South West Growth Centres.
Starting in 2008, the NSW Government established a $530 million Growth Centres conservation fund to protect areas of biodiversity value. The program was allocated $397.5 million of the total $530 million in funding over 30 years to acquire land, establish conservation agreements, or purchase and retire biodiversity credits outside the Growth Centres or a combination of these actions. This funding has been derived partly from a special infrastructure contribution (SIC) applying to development in the Growth Centres and partly from the government's Consolidated Fund equally shared 50:50.
Growth Centres Biodiversity Offset certification extension
On 6 June 2025, the Minister for the Environment signed the Order extending biodiversity certification of the Growth Centres State Environmental Planning Policy (Sydney Region Growth Centres) 2006 for one year to 30 June 2026.
This determination was published in the NSW Gazette on 20 June 2025 (PDF 1.3MB).
During the one-year extension period, a comprehensive review of the certification will be completed. Depending on the outcomes of the review, the certification may be extended for up to 9 more years to 2035, enabling recommendations identified during the review to be implemented and any remaining offset commitments for the certification to be met.
Public consultation for any further extension is anticipated in early 2026.
What's been achieved
As of 2024, the Growth Centres Biodiversity Offset program has permanently protected approximately 900 hectares of land at 24 locations in Western Sydney, comprising 23 biodiversity stewardship sites and one reserve.
These sites protect threatened plant communities, including critically endangered Cumberland Plain Woodland, and provide valuable habitat for threatened animal and plant species.
How the program works
The program delivers offsets for the NSW Government under 3 agreements:
- Biodiversity Certification of State Environmental Planning Policy (Sydney Region Growth Centres) (2006)
- Strategic assessment approval of the Western Sydney Growth Centres (2012)
- Mulgoa biobank site funding agreement with the Australian Government (2013).
In accordance with the biodiversity certification, the program receives funding annually at the same rate at which development is expected to occur in the growth centres. The program has also been supported by grants of additional funding from the NSW Government and the Australian Government.
The program spends the funds, as a first preference, within priority areas that contain the largest remaining areas of high conservation value bushland on the Cumberland Plain. If it is not possible to create a reserve, the program will protect the land by entering into biodiversity stewardship agreements (previously known as biobanking agreements) with existing landowners.
Biodiversity stewardship agreements are a type of permanent conservation agreement in which funding for site management is invested in an endowment fund (the Biodiversity Stewardship Payments Fund). The fund provides ongoing annual payments to the landowner, allowing the ongoing management of the bushland.
