Major development applications and assessments
Information about Major developments and their assessment process is available on the SA Planning portal.
The Minister for Planning can declare a proposed development or land use a major development if it is of state economic, social or environmental significance.
A declaration is the start of a rigorous, whole of government assessment process and does not imply government support or otherwise for the proposal. You can have your say about Major developments as part of the assessment process.
Major projects are assessed in different ways, depending on where the development is proposed and when it is lodged for assessment.
From July 2020, a major project proposed in an rural or outback area is assessed under the Planning, Development and Infrastructure Act 2016. These proposals are called impact assessed developments.
Until September 2020 a major project proposed in an urban or suburban council area in South Australia is assessed under the Development Act 1993. These proposals are called major developments.
