Eligibility based on service in Namibia is designed to recognise that members of the Australian Defence Force could be required to undertake operations of a warlike nature in areas where there were incidents of a local sporadic nature rather than continuing operations. Accordingly, eligibility is based on the principle that benefits should stem from a period of service in which the member was exposed to hazards of a warlike nature beyond those of normal peacetime duty and depended upon allotment for duty in a prescribed “operational area”.
An eligible person therefore, is a person who, as a member of the Defence Force (which by definition includes any Reserve Force), rendered service as a member of the United Nations Transition Assistance Group (UNTAG) Namibia, in the area described in item 9 in Schedule 2 to the Veterans' Entitlements Act 1986, between 18 February 1989 and 10 April 1990 inclusive.
A list of all individuals allotted for duty can be found on CLIK[Legislation / Service Eligibility / Service Determinations / Schedule 2 — Operational Areas / Item 9: Namibia (1989–1990)]
A person with otherwise appropriate service may be ineligible if that service ended due to misconduct or misbehaviour (please see Eligibility GO 11 for full details). However, this exclusion does not apply to the widow, widower or dependent parent of a person whose service ended due to misconduct or misbehaviour.
