Australia is defined in the Acts Interpretations Act 1901 and includes the following territories and Islands:

• Christmas Island
• Cocos (Keeling) Islands

Subsection 5Q(1) of the VEA provides specifically that the definition of Australia includes the external territories for many VEA purposes including Part III, IIIAB, some parts of Part IIIB, Parts IIID, VIIA, VIIC and sections 52ZO, 58A, and 132.  Norfolk Island is currently the only external territory of Australia. For the above VEA sections, which cover service pension, [glossary:income support supplement:118], pension bonus, pension loans scheme, Veterans supplement, pension supplement and Commonwealth Seniors Health Card purposes it is considered to be part of Australia. The test of residing in Australia does not by itself satisfy the full definition of Australian Resident, as residency also requires Australian citizenship or the holding of a specified visa.

Papua New Guinea and Nauru have both previously been external territories of Australia.  Lord Howe Island and Macquarie Island, formerly regarded as separate islands, are now part of mainland NSW and Tasmania respectively.

Veterans' Entitlements Act 1986.

A service pension is an income support payment broadly equivalent to the social security age and disability support pensions. It may be paid once a veteran or partner has reached the nominated age or is incapacitated for work.

ISS is an income support payment that may be paid to eligible war widows and widowers under the VEA and persons receiving wholly dependent partners' compensation under the MRCA, and who satisfy the means tests. It is an indexed rate, increased twice-yearly in March and September in line with changes to the cost of living and/or average wages. Income Support Supplement (ISS) legislation commenced on 20 March 1995. It is a payment created to replace the ceiling rate income support age, carer, wife and disability support pensions, paid to war widows/widowers by Centrelink.
