The Regiment was formed on 26 April 1966 as the 1st Division Army Aviation Regiment and was re-designated the 1st Aviation Regiment on 31 March 1967. The regiment had historically operated a mix of fixed-wing and rotary aircraft. On 15 January 2021, Minister for Defence
Linda Reynolds announced that the
Boeing AH-64E Apache Guardian had been selected for Project Land 4503 to replace the Tiger ARH. A fleet of 29 Apaches will be acquired with a planned
initial operational capability of 12 helicopters in 2026 and
full operational capability in 2028. The
Defence Strategic Review in April 2023 stated that coinciding with the introduction of the new Apache fleet, the regiment would be relocating to
RAAF Base Townsville, where it would be based alongside C Squadron of the
5th Aviation Regiment who operate the
CH-47F Chinook. The regimental headquarters and 161 Reconnaissance Squadron relocated to Townsville in 2025. 162 Reconnaissance Squadron will remain in Darwin until the Tiger helicopters are retired. As of November 2025, four AH-64Es had been delivered. ==Current organisation==
