A plain English explanation of this ACT planning and property term.
DA documentation and further-information requests form part of the ACT development assessment process. DA documentation is the required information submitted with a development application to demonstrate compliance with planning requirements, while a further-information request is a formal request for additional information needed to properly assess and determine the application.
A valid DA must include the plans, reports and supporting material required for its development type. If the material is incomplete or does not demonstrate the assessment outcomes, the authority can seek further information, delaying assessment. The 2026 minimum-documentation guideline should be used as an intake checklist.
