In 1978, the Australian government decided to purchase two passenger jets for strategic transport, primarily to mitigate what it saw as the risk of terrorist attack inherent in carrying VIPs on commercial flights. Its attempts to procure one Boeing 727 each from domestic carriers Ansett and TAA were unsuccessful but, in December, Qantas agreed to sell the government two Boeing 707s for $14.5 million. Purchasing big jets for VIPs was controversial, but the 707s were also intended for general long-range transport, being capable of carrying cargo or up to 160 passengers. The first was transferred to the RAAF in March 1979, and its inaugural Air Force flight took place on 22 April. Located at RAAF Base Richmond, New South Wales, the 707s were initially operated by No. 37 Squadron. They were formed into No. 33 Flight under the command of Wing Commander J.D. Grierson on 2 February 1981. The flight's first mission took place the same day, when it ferried RAAF members and their families to RAAF Base Butterworth, Malaysia, a task that had previously necessitated a Qantas charter.
