Pursuant to section 96 of the Freedom of Information Act 1992 the department has published the pdfInformation Statement 2020. Please refer to this document for more information on the types of documents held by the department and how they can be accessed.

The Freedom of Information Act 1992 (FOI Act) gives every person the right to seek access to documents held by government agencies. Documents may comprise written material, plans and drawings, photographs, tape recording, films, videotapes or information stored in a computerised form.

Under the FOI Act applications for access to information held by the department must:

  • be in writing
  • give enough detail to identify the requested documents; or if the application is for amendment of personal information, details must be provided to show how or why the agency's records are inaccurate, incomplete, out of date or misleading;
  • give an Australian address, and where possible, a contact telephone number; and
  • be lodged at the office of the agency that would be expected to hold the documents, together with any application fee payable.

Fees and charges

  • No fees or charges apply for requests for personal information or amendment of personal information about the applicant (i.e. details of employment, etc.).
  • Applications for documents held by the department which contain non-personal information, require a $30 application fee to validate the application. Payment can be made on-line by credit card at https://dwer.wa.gov.au/make-a-payment.

Applications will be acknowledged in writing and the applicant will be notified of a decision within 45 days.

It is the aim of the department to make information available as soon as possible and at the least possible cost. Whenever possible, documents will be provided outside the FOI process. The agency is, however, mindful of its obligations including but not limited to, the workings of Government, confidentiality, and the rights of third parties in relation to personal and business/commercial information.

Contaminated Sites
Information on contaminated sites can be accessed under the Contaminated Sites Act 2003 and is therefore not available through FOI.

The Contaminated Sites Database holds details on sites classified:

  • contaminated – remediation required
  • contaminated – restricted use
  • remediated for restricted use

Information on all other reported sites including those awaiting classification, is recorded on the Contaminated Sites Register and can be requested upon completion of Form 2, with a search fee of $30.
