During the 1980s the annual Open Days at the Watsonia Army Base in Melbourne were always well-supported by an air element, including RAAF Chinooks of 12 Squadron. A15-012 was present at the 1981 display. Delivered new to the RAAF in March 1974, it was returned to the USA in September 1993 in a remanufacturing deal with Boeing and upgraded to CH-47D standard for the US Army, serial 93-934.
