The Royal Australian Air Force purchased 57 F/A-18A fighters and 18 F/A-18B two-seat trainers to replace its Dassault Mirage IIIOs. Numerous options were considered for the replacement, notably the F-15A Eagle, the F-16 Fighting Falcon, and the then new F/A-18 Hornet. The F-15 was discounted because the version offered had no ground-attack capability. The F-16 was considered unsuitable largely due to having only one engine. Australia selected the F/A-18 in October 1981.[55] Original differences between the Australian and U.S. Navy's standard F/A-18 were the removed nose-wheel tie bar for catapult launch (later re-fitted with a dummy version to remove nose wheel shimmy), addition of a high frequency radio, an Australian fatigue data analysis system, an improved video and voice recorder, and the use of instrument landing system/VHF omnidirectional range instead of the carrier landing system.

The first two aircraft were produced in the US, with the remainder assembled in Australia at Government Aircraft Factories. F/A-18 deliveries to the RAAF began on 29 October 1984, and continued until May 1990.[58] In 2001, Australia deployed four aircraft to Diego Garcia, in an air-defense role, during coalition operations against the Taliban in Afghanistan. In 2003, 75 Squadron deployed 14 F/A-18s to Qatar as part of Operation Falconer and these aircraft saw action during the invasion of Iraq. Australia had 71 Hornets in service in 2006, after four were lost to crashes.

The fleet was upgraded beginning in the late 1990s to extend their service lives to 2015. They were expected to be retired then and replaced by the F-35 Lightning II. Several of the Australian Hornets subsequently had refits applied to extend their service lives out further to a new planned retirement date of 2020. Australia has also purchased 24 F/A-18F Super Hornets, with deliveries beginning in 2010.
