The State Planning Commission with the support of the Department of Trade and Investment, Planning and Land Use Services (PLUS) is preparing a new Greater Adelaide Regional Plan (GARP). As part of the process for the preparation of the GARP, the Commission and PLUS have prepared the Greater Adelaide Regional Plan Discussion Paper to support Stage 1 engagement for the Greater Adelaide Regional Plan.

Please note this is a State Government consultation.

Whilst this project will be managed by the Department of Trade and Investment, Planning and Land Use Services, its relevance extends to City of Onkaparinga residents, and we want to ensure that awareness is raised, and an opportunity is created for input.


The Discussion Paper is a robust evidence-based document with a strong focus on what the region might look like in 30 years' time and presents key considerations and trends that we need to consider in our future planning.

Public consultation on the Discussion Paper will commence for a period of 12 weeks, starting on Monday 14 August 2023, providing opportunities for stakeholders to have early input into forming the new GARP and help determine:

  • what Greater Adelaide might look like in 30+ years, and the implications of trends and projections on future planning.
  • the potential options for future urban form – including constraints and opportunities.
  • the needs and wants of current and future communities.

Further information on consultation activities and promotion for the Discussion Paper will be updated as the information is released and can be viewed here(External link).

We extend an invitation to engage in the consultation process and share your valuable insights. This engagement plays a crucial role in shaping the future development and growth of South Australia, considering aspects such as future population and employment, housing affordability, and the quality of life for the South Australian metropolitan region.
