Site Information


As a result of military training and live firing undertaken by Australian and Allied forces there are many areas throughout Australia not controlled by the Commonwealth, which may be subject to residual Unexploded Ordnance (UXO) contamination. In accordance with the Commonwealth Policy, the Department of Defence has undertaken to identify and record sites where there is potential for such contamination.

The role of the Directorate of Environmental Remediation Programs (Unexploded Ordnance) (DERP (UXO)) is to gather and disseminate information that will assist in the safe management of land in Australia that may be subject to UXO contamination. This Internet site is designed to provide general information and advice regarding the potential for particular areas of land being contaminated with UXO.

Information included here is drawn from a range of sources. These include the following:

  1. Australian Defence Force Explosive Ordnance Incident Reports (EOIR) and Explosive Ordnance Disposal Reports (EODR)
  2. Commonwealth Gazettes, Unit War Diaries and other records
  3. current and recently archived Defence files
  4. field investigation surveys
  5. other government agencies.

The Commonwealth cannot warrant the completeness of the information contained in these sources, or guarantee that they are the only possible sources.

Defence regularly updates the information contained on this site as further information becomes available.
UXO contamination site data for Western Australia is provided by the Department of Fire and Emergency Services (DFES) of WA, and copyright is owned by the State of Western Australia.

Sites which are known or suspected of having been used for military activity are categorised according to the assessed potential for UXO contamination on that site. If appropriate, sites have been divided into assessment zones. Assessments of residual UXO potential will refer to substantial, slight or other levels. Land parcels within designated assessment zones retain their assessment unless they have been appropriately investigated or remediated. Site assessments reported here do not necessarily reflect any UXO investigations or remediation operations of land parcels that have been conducted on behalf of any person or organisation other than Defence.

Defence's categorisation criteria; complete with the respective UXO warning and advice, and Defence's recommendations to State and Local Authorities, is available here on the following page: UXO Categorisation Criteria, Warnings and Advice.
