force, the loss of any of these aircraft in combat would have inflicted a heavy blow on Australia's reconnaissance capability. The second preference in the advice put to the government was to deploy a squadron of four to eight F-111Cs, though Defence did not support this. In the event, the government decided to not expand the Australian force. As a result, the F-111Cs' contribution to the war was limited to conducting intensive exercises with the Naval ships as they sailed through Australian waters en route to the Persian Gulf. The Australian-led INTERFET intervention into East Timor in September 1999 marked the closest Australia's F-111s ever came to combat. F-111s from both No. 1 and No. 6 Squadrons were deployed to RAAF Base Tindal, Northern Territory, on 28 August to support the international forces, and remained there until 17 December 1999. This was a maximum effort for No. 82 Wing, and up to 10 F-111Cs were available at Tindal; No. 1 Squadron's commitment peaked at six aircraft and about 100 personnel. No. 75 Squadron also maintained 12 F/A-18s at its home base of Tindal to support INTERFET if needed. From 20 September, when INTERFET began to arrive in East Timor, the F-111s were maintained at a high level of readiness to conduct reconnaissance flights or air strikes if the situation deteriorated. For the latter role two F-111s armed with concrete-filled bombs fitted with precision guidance kits were kept available at all times. INTERFET did not encounter significant resistance, however, and F-111 operations were limited to reconnaissance missions conducted by RF-111Cs from 5 November. Each of these sorties were made after gaining approval from the Indonesian government and normally focused on bridges and communications installations. The last RF-111C flight over East Timor took place on 9 December. War games had the F-111s achieving complete success if a strike was necessary against Indonesian military headquarters near the capital. Other roles and controversies The Royal Australian Air Force's F-111 fleet was at times controversial. The long delay to the delivery of the aircraft was a significant political issue in the late 1960s and early 1970s. This occurred around the same time that massive delays and cost blowouts to the Sydney Opera House were making headlines, prompting some commentators to dub the F-111 the "Flying Opera House". In 1983 the Hawke government tasked an RF-111 to take surveillance photos of the Franklin Dam project in
