When the BASIX service was transferred to the NSW Planning Portal, some “in progress” and completed projects were also migrated across.

You can access your “in progress” projects last accessed on or after 1 January 2021 from the Active work tab on the NSW Planning Portal. Note: Any projects last accessed before 1 January 2021 were not migrated to the NSW Planning Portal and are unable to be accessed. Please start a new BASIX application for your proposed development.

All completed BASIX certificates (projects), including those you have archived, are located in your BASIX historical work folder, accessed via the top left-hand navigation menu.
