No. 30 Communications Unit was headquartered at Iwakuni, along with the rest of No. 91 Wing's components except No. 77 Squadron, which was based on the Korean peninsula. It was initially commanded, unofficially, by Flight Lieutenant (later Air Commodore) Dave Hitchens. According to Hitchens, "Having commanded the communications flight in No. 77 Squadron, I assumed control but had no formal authority to do so, but nobody told me to stop." The transport aircraft included the personal Dakota of the BCOF commander, Lieutenant General Sir Horace Robertson, operating under his direction. During November 1950, the unit received another four Dakotas from No. 38 Squadron (of No. 90 (Composite) Wing in Malaya), giving it a total strength of eight Dakotas and two Austers. It supported all Australian forces in Korea. One of its key functions was medical evacuation, but it was also responsible for supply drops, search and rescue, reconnaissance, and mail delivery, as well as transporting cargo, troops, and VIPs. Unlike No. 77 Squadron, it was not tasked by the US Fifth Air Force but instead operated under Australian control, exercised through BCOF headquarters in Japan. In December 1950 the unit undertook "Operation Haggis", the delivery of of haggis to the Argyll and Sutherland Highlanders based in Suwon, Korea. The same month, a United States Air Force Mustang taking off from Suwon smashed into the cockpit of one of the Dakotas; none of the Australian crew was injured but the aircraft had to be written off and stripped for components by No. 491 Squadron.
