The Commonwealth of Australia and Western Australia have entered into a bilateral agreement under the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act) relating to environmental assessments. Among other matters, the agreement includes the clearing permit assessment process under Part V Division 2 of the Environmental Protection Act 1986 (EP Act).

The bilateral agreement allows the state to conduct environmental assessments on behalf of the Commonwealth, removing duplication including the need for a separate Commonwealth assessment.

The bilateral agreement began on 1 January 2015.

Applications under the assessment bilateral agreement

Clearing activities intended to be assessed under the assessment bilateral agreement must initially be referred by the applicant to the Commonwealth using the relevant forms on DAWE’s website at www.environment.gov.au.

After the Commonwealth Minister for the Environment determines that the clearing action is a 'controlled action', you must submit an EP Act clearing permit application using the relevant DWER application forms below. Clearing permit applications assessed under the assessment bilateral agreement must be supported by a document describing:

  • the proposed clearing action
  • likely relevant impacts on the matters of national environmental significance
  • feasible alternatives to the proposed clearing action;
  • mitigation measures, and
  • assessment of the relevant impacts of the clearing.
