surrender on 2 September 1945. The Pacific Star was instituted by the United Kingdom in May 1945 for award to those who had served in operations in the Pacific Campaign from 8 December 1941 to 2 September 1945. Award criteria The eligibility criteria for the award of the Pacific Star were different for service at sea, on land and in the air. General No recipient could receive both the Pacific and the Burma Stars. A clasp inscribed 'Burma' was instituted to be worn on the Pacific Star's ribbon by those who earned the Pacific Star and who subsequently qualified for the Burma Star. The award of a gallantry medal or Mention in Dispatches qualified the recipient for the award of the Pacific Star, regardless of service duration. Those whose qualifying service period was terminated prematurely by their death or disability due to service were also awarded the Star. Service afloat Naval personnel qualified for service at sea within certain specified boundaries.

In 1994, the Australian government conducted a review of the conditions for award of the Pacific Star, as set out in Command Paper 6833 of June 1946. As a result, the conditions for award were amended to include any member of the Australian military who was on board the Australian Hospital Ship Centaur when it was torpedoed and sunk on 14 May 1943. The Pacific Star can be awarded to these men and women regardless of whether they had been awarded or were eligible for the 1939–1945 Star, the Australia Service Medal 1939–1945 or any other campaign award. Certain special conditions applied governing the award of the Pacific Star to those Naval personnel who entered operational service less than six months before the end of the war. Those who entered operational service in the qualifying area on or after 7 March 1945 and who did not thereafter serve in the area qualifying for the Burma Star, could qualify for the Pacific Star by entry into
