It was dedicated in the presence of Peter Hollingworth AC OBE, Governor General of the Commonwealth of Australia; John Howard, Prime Minister of Australia; and Air Marshal Angus Houston AC AFC, Chief of Air Force.
[citation needed] The central sculpture was designed by Inge King to commemorate the 50th anniversary of the formation of the RAAF, and was unveiled in 1973.
It symbolises the aspirations and achievements of the RAAF; the three upturned wing shapes representing the endurance, strength and courage of RAAF people, while the bronze flight sculpture in the centre embodies man's struggle to conquer the elements.
The RAAF motto is inscribed on the base: PER ARDUA AD ASTRA : Through struggle to the stars.
