1. Korean war veterans

For the purposes of the study, 'Korean War veterans' were defined as:

All members of the Royal Australian Navy, Australian Army, Royal Australian Air Force (including those airmen based in Japan who flew operational missions over Korea), who landed in Korea or entered Korean waters, including those who were seconded to the Army of the Republic of South Korea, the United States Air Force (USAF), the United States Navy (USN), the British Army, Navy or Air Force and any other allied Service; all members of philanthropic organisations; all members of the Australian Forces Overseas Fund and all official entertainers and war correspondents who saw service in Korea during the period between 27 June 1950 and 19 April 1956.

This definition excludes:

members of the diplomatic corps;
entertainers other than those who were regarded as 'official';
members of the Army of the Republic of Korea or of any other army who have become Australian citizens subsequently;
Australian citizens employed in Korea by overseas business organisations or governments;
civilian non-medical aid and charity workers other than members of philanthropic organisations who were accredited to the Australian Defence Force; and merchant mariners

2. 'Allotted for Duty' and 'Operational Service'

Under the Veterans' Entitlements Act 1986 (VEA), the terms 'Allotted for Duty' and 'Operational Service' have the following meanings:

Allotted for Duty means a person or unit of the Defence Force that was allotted for duty in an operational area. Allotment may be retrospective or prospective, and occurs via a written instrument issued by the Defence Force; and
Operational Service is rendered where a person is allotted for duty and serves in an operational area. Current use of this term is not the same as normal posting procedures used in the Defence Force to move members from one unit to another.

3. Tours and visits

For the purposes of this study, a visit is defined as service of less than 28 consecutive days on land in Korea or on ships operating off the Korean coast. In contrast, a tour is defined as service equal to or more than 28 consecutive days on land in Korea or in ships operating off the Korean coast.
