The Minister for Planning can deem that a State significant infrastructure project is essential for the State for economic, environmental or social reasons. These applications are known as critical State significant infrastructure. Critical State significant infrastructure proposals are determined by the Minister.
The Department has prepared standard Secretary’s Environmental Assessment Requirements (SEARs) for critical State significant infrastructure projects in consultation with other government agencies.
The objectives of the Standard SEARs are to:
- cause the greatest impact;
- affect the most sensitive aspects of the environment; and
- are of greatest interest or concern to the community.
All SSI applications are listed on the Department’s major projects website. The application and all supporting information are available to view online. The website's tracking system identifies what stage a project is up to in the assessment process.
The Department’s assessment report and the application determination (including conditions of consent or reasons for refusal) are also made available to view on the major projects website.
The Minister for Planning is the consent authority for SSI applications. SSI applications are assessed by the Department of Planning and Environment. In some cases, the Minister may delegate the decision making function to Department staff.

An applicant can apply to the Minister for Planning to modify an SSI approval. Requests must be lodged with the Department of Planning and Environment for assessment. The modification request will be appropriately notified / exhibited depending on the scale of the proposed modification and the potential for environmental or social impacts.
The department has prepared sets of standard and model conditions to help infrastructure providers understand the types of conditions likely to be applied to State significant projects if they are approved.
By providing these sets, the department aims to:
In developing the conditions, the department has considered feedback from industry, councils and other government agencies.
