Categorisation Criteria, Warnings and Advice


In those areas which have been categorised, assessments of residual Unexploded Ordnance (UXO) potential will refer to substantial or slight levels. Land parcels within designated slight or substantial zones retain their assessment unless they have been appropriately investigated or remediated.

Defence provides this advice to the appropriate State or Territory authorities. Whilst Defence endeavours to keep the information as accurate as possible, it is not possible for Defence to record changes relating to remediation at the individual Lot/Plan level. Advice as to the current conditions and requirements should be referred to the appropriate State or Territory Authority.

Defence recommends that, State or Local authorities should take action, as far as practical, to:

  1. Notify affected landowners that their property is in a slight or a substantial potential UXO contamination area, as appropriate.
  2. Publicise the authority’s requirements for UXO investigation and remediation, in respect to land usage and development.
  3. Inform affected landowners, residents and those working in these areas that the area was used for military activities and ensure that they receive the appropriate UXO warning and advice as issued by Defence.

Substantial

Sites categorised as being substantial will have a history of numerous UXO finds or heavy residual fragmentation. Areas likely to be assessed as substantial include impact areas, demolition sites and areas of heavy explosive ordnance dumping.

Warning: Allied Defence Forces used many areas throughout Australia, during and after World War II, for encampments, field training, live firing of weapons and other military activities. This property is on such a site. A possibility exists that dangerous items of Unexploded Ordnance (UXO) may still be found on this site. If you should find a suspicious item, that may be a UXO, do not touch or disturb it. It has been there for many years, it will not hurt you if you do not disturb it. There are no known instances, in Australia, where UXO have caused injuries except when they were deliberately and intentionally disturbed. Contact police they will arrange for military experts to attend and dispose of it.

Advice: All land usage may continue without specific UXO search or remediation, subject to an appropriate risk assessment. Development and/or land usage re-zoning proposals for land parcels considered to be subject to a substantial UXO should only proceed following the conduct of UXO investigation and remediation.

Slight

Areas categorised as slight will have a confirmed history of military activities that have resulted in residual UXO but which Defence considers it inappropriate to assess as substantial.

Warning: Allied Defence Forces used many areas throughout Australia, during and after World War II, for encampments, field training, live firing of weapons and other military activities. This property is on such a site. A possibility exists that dangerous items of Unexploded Ordnance (UXO) may still be found on this site. If you should find a suspicious item, that may be a UXO, do not touch or disturb it. It has been there for many years, it will not hurt you if you do not disturb it. There are no known instances, in Australia where UXO have caused injuries except when they were deliberately and intentionally disturbed. Contact police they will arrange for military experts to attend and dispose of it.

Advice: All land usage and development, within these areas, may continue without further UXO investigation or remediation.

Other

Defence records confirm that the area was used for military training but do not confirm that the site was used for live firing. UXO or explosive ordnance fragments / components have not been recovered from the site. Defence opinion is that it would be inappropriate to assess as either slight or substantial.

Warning: Allied Defence Forces used many areas throughout Australia, during and after World War II, for encampments, field training, live firing of weapons and other military activities. This property is on such a site; however no specific UXO contaminated site has been identified in the area. If you should find a suspicious item, that may be a UXO, do not touch or disturb it. It has been there for many years, it won’t hurt you if you don’t disturb it. There are no known instances, in Australia, where UXO have caused injuries except when they were deliberately and intentionally disturbed. Contact police they will arrange for military experts to attend and dispose of it.

Advice: These sites have been included for general information purposes only. Defence makes no recommendations in regards to this category.
