After a development application has been lodged, the applicant is still able to make some changes to the application. For example, the applicant may change the application in response to:

  • public submissions
  • advice received from a concurrence or advice agency.

If a change is made to an application and the change is a minor change, the IDAS process does not stop and the notification stage (if applicable) does not have to be repeated. For the definition of minor change, see Section 350 of the Sustainable Planning Act 2009 (PDF icon 2.5 MB).

If the change deals with matters raised in submissions or information requests, the IDAS process does not stop, but re-notification may be required.

For all other changes, the IDAS process re-starts from the acknowledgement period.

Further details on what change can be made are provided in the Statutory guideline 06/09 Substantially different development when changing applications (PDF icon 104 KB).
