There are many ways to find buyers and sellers to trade biodiversity credits, including:

  • searching the public registers
  • exploring advertised credits in the online biodiversity credits catalogue and using the listed contacts to contact sellers
  • selling to or buying from the Biodiversity Credits Supply Fund
  • selling to the Biodiversity Conservation Trust
  • using other third-party intermediaries
  • negotiating directly with development proponents or landholders.

Biodiversity credits public registers

The department is required to maintain public registers that provide information about people who are looking to buy and sell biodiversity credits. You can use these public registers to find credits you need and contact buyers and sellers.  

The 2 main credits registers are:  

BioBanking public registers, which were established under the repealed Threatened Species Conservation Act 1995 (NSW) for the previous BioBanking Scheme, may also include relevant supply and demand information. All credits and obligations created under the previous scheme remain valid under transitional arrangements. Visit the BioBanking public registers.

Credits wanted and expression of interest listings via the BOS Portal are currently unavailable

Following the launch of the BOS Portal on 1 June 2026, automated credits wanted (CW) and expression of interest (EOI) listings will be unavailable.

This means that listings on the CW and EOI registers will not be live, and the registers will only show listings before the commencement of the BOAMS offline period on 19 May 2026.

Users must refer to the static registers for existing listings and the temporary manual list for current listings.

BOS Portal

The new BOS Portal replaces BOAMS, providing a more modern and user-friendly system. The function for users to make credits wanted (CW) and expressions of interest (EOI) listings via the BOS Portal will be unavailable following the initial launch. This means that automated CW and EOI updates to the department’s public registers will also be offline.

It is expected that this function will be available in late 2026 as part of future planned updates to the BOS Portal. In the interim, the department has established a manual process that enables users to request new EOI or CW listings.

Which functions will be offline 

  • Availability and submission: The functionality to create and submit new CW and EOI listings via the BOS Portal will be unavailable following its launch.
  • Listing and register updates: Automated updates to the public registers via the BOS Portal will also be suspended. New listings and changes to current listings can be made via a manual process during this period.

How to submit a manual listing or request a change to a current listing

Users can submit CW and EOI listing and change requests using the following manual process.

  1. 1. Download the applicable template

    Access the new listing and change listing template:

  2. 2. Complete the template

    Fill out all relevant sections of the template.

  3. 3. Submit via email

    Send the completed template to [email protected].

  4. 4. Receive confirmation

    You will receive a notification email once your request has been processed and the listing has been manually updated on the register.

How to check all credits wanted and expression of interest listings on the website

The current CW and EOI registers will only include listings in place before 1 June 2026 and will remain a point-in-time snapshot. Users will therefore need to refer to the CW and EOI registers (for static listings) and download a copy of the interim CW and EOI register.

Website locations for CW and EOI listings are as follows:
