The opening of Parliament House, Canberra, in 1927. In early 1924, a cleared paddock (now playing fields near the Canberra suburb of Dickson) was the designated airfield for Canberra; known as the Northbourne Aviation Ground. Canberra was not a scheduled destination for very early airlines and pilots, so the aviation ground was mostly used for emergency landings for aircraft on domestic routes. In late 1926, Parliament House was almost complete and celebrations were to include a Royal Australian Airforce (RAAF) flying display. The Dickson airfield was considered unsuitable to host the variety of aircraft expected.
