The WAPC has State-wide responsibility for integrated urban and regional land use planning and development, working in conjunction with State and local government to develop a system, policies and plans for the long term benefit of the Western Australian community. The WAPC is established under the Planning and Development Act 2005 which defines its functions including:
- advising the Minister for Planning on strategic land use planning and development, legislation and planning schemes
- maintaining the State Planning Strategy to provide a vision for the future development of Western Australia
- developing integrated land use planning strategies and policies for the coordination of transport, infrastructure and development
- preparing and reviewing region schemes to cater for anticipated growth
- researching and developing planning methods and models relating to land use planning, land development and associated matters (including monitoring land and housing supply)
- reserving and acquiring land for public purposes in region planning scheme areas
- making statutory decisions on a range of planning application types including applications to subdivide land and significant development.
The WAPC operates with the support of the Department of Planning, Lands and Heritage, which provides professional and technical expertise, administrative services, and corporate resources, and which undertakes a number of WAPC functions under delegation.
A review of the WAPC was conducted in 2022 which resulted in a number of reforms being introduced through the Planning and Development Amendment Act 2023. These reforms were complemented by operational changes to increase the efficiency of the WAPC and its focus on strategic planning.
From July 1 2024, the following changes were introduced:
- a smaller, more strategically focused WAPC board of nine members with diverse expertise relevant to planning and Board functions
- refinement of the statement of functions to provide a clearer and more comprehensive outline of the WAPC's responsibilities
- the reallocation of some responsibilities from the WAPC board to the Statutory Planning Committee, including determination of most Part 11B significant development applications
- opening meetings to the public for statutory planning proposals where the WAPC is the final decision-maker for increased transparency
- introduction of livestreaming where meetings are open to the public.
