Their probe-and-drogue configuration allowed them to refuel the RAAF's F/A-18 Hornets and the Royal New Zealand Air Force's Douglas A-4K Skyhawks, but not the RAAF's General Dynamics F-111 bombers, which required a boom system; the other two 707s continued to be used purely for long-range transport. The RAAF had argued for an air-to-air refuelling capability for both the and the , but the Australian government refused to fund the latter, considering the F-111's existing range sufficient for deterrent purposes. Observers such as journalist Frank Cranston speculated that aside from any cost issues, the government was concerned that extending the bombers' range would signal to the region that Australia was adopting a more aggressive defence posture. In April 1989, one of the 707s transported 300 Australian Army personnel in two flights to Namibia as part of the Australian contribution to UNTAG, the United Nations Transition Assistance Group policing the country's transition to independence. Later that year, the squadron helped ferry members of the Australian public when the two domestic airlines were grounded during an industrial dispute; it was similarly employed in 1991 following the demise of Compass Airlines. On 29 October 1991, one of the transport-configured 707s crashed into the sea during a training flight out of East Sale, Victoria; all five crew members were killed. The coronial inquest into this accident found that training in the asymmetric handling manoeuvre that caused the crash was deficient, and that the RAAF lacked a proper understanding of the handling characteristics of its 707s. The Coroner's first recommendation related to the need for appropriate simulation for this type of training, an area not properly recognised or addressed by the RAAF at the time. No. 33 Squadron transported Australian troops to and from Somalia as part of Operation Solace in 1993. In January 1998, still based at Richmond, No. 33 Squadron joined Nos. 32 and 34 Squadrons under No. 84 Wing. Two of No. 33 Squadron's aircraft were soon employed to form No. 84 Wing Detachment A in Kuwait, as part of Operation Southern Watch. On 5 March, one of the 707s undertook the first operational aerial tanker mission since the squadron's re-formation in 1983, when it refuelled six Panavia Tornados of the Royal Air Force (RAF) over Saudi Arabia. The detachment subsequently refuelled US F/A-18 Hornets, Northrop Grumman EA-6 Prowlers and McDonnell Douglas AV-8 Harriers, and RAF British Aerospace Harriers, as well as the
