This is a non-flying replica built by Qantas. It is of the airline's first aircraft . That was an Australian made 504K fitted with a Sunbeam Dyak engine. Became G-AUBG. and later VH-UBG. Withdrawn from use in 1932. In 1965 Qantas fitted a Dyak engine to a borrowed 504K, A3-4, owned by the Australian War Memorial. It was painted like the replica. Returned in 1987 with its rotary engine refitted and in RAAF markings. Qantas by then had built two replicas of G-AUBG, one of which is pictured.

G-AUBG prior to receiving its registration. It remained with QANTAS until November 1926 when it was sold. Became VH-UBG when Australia adopted that prefix in 1929 and was struck off the register in April 1932 after the CoA expired. The engine is a Sunbeam Dyak. RAAF 504K A3-4 was lent to Qantas in 1965, fitted with a Dyak and painted to represent G-AUBG. This aircraft was returned to the Australian War Memorial in 1987. It had been replaced by a replica of G-AUBG now displayed at the Qantas Founders Museum at Longreach. Photo from: National Library of Australia

One of the most important aircraft in Australian aviation history, VH-UER was the first air ambulance. It graces the Australian $20 note along with a portrait of John Flynn, the founder of an air ambulance service in outback Queensland that evolved into the Royal Flying Doctor Service. -UER was sold in 1934 and wrecked when it ditched near Caloundra on December 8, 1935.

Built by Qantas under licence from de Havilland. Reregistered VH-UHE by August 1930. Crashed near Winton, Queensland, October 3, 1934. Photo from: Hudson Fysh Collection/State Library of New South Wales

One of the first aircraft in the Qantas fleet, G-AUBF served until its certificate of airworthiness expired in 1926. Hudson Fysh, the founder of the airline, described it as the best aircraft used by the fledgling airline. Photo from: Hudson Fysh Collection/State Library of New South Wales

Camooweal, population 200, has an airport in 2019 but back when VH-UJM visited it likely landed at the racecourse and taxied up the main street to the pub. The aircraft passed through several hands after Qantas before ending up in Papua New Guinea where it was destroyed by enemy action during World War II. Photo from: State Library of Queensland

Qantas sold G-AUFW in 1931 by which time it was VH-UFW. Crashed at Capella, Queensland, on July 19, 1936. Qantas liked the DH.50 and built several some, like FW, with Siddeley Puma engines and others with Bristol Jupiter radials. Photo from: Hudson Fysh Collection/State Library of New South Wales

Became G-AUBF, one of about 50 aircraft placed on the British-Australian G-AU** register on its first day, June 28, 1921. It served with Qantas until 1926 when its Certificate of Airworthiness expired. From its base in Longreach, C6986 undertook joy flights at many towns in western Queensland as the fledgling airline prepared to start regular services.

Qantas disposed of VH-UJB in 1935 to an operator in Papua New Guinea, where it crashed on May 6, 1938. Qantas photo.

Using Avro 504 parts, the 547 was a five-seater with an extra set of wings to lift the heavier load. Proved unsuitable for Australian conditions and ended up as a chicken coop in Sydney. May never have been used on Qantas services. A second more powerful 547 for the UK Air Ministry was deemed too slow and too unstable and was quickly scrapped. Photo from: State Library of Queensland

VH-ULG was one of three DH.50s built by Qantas with Bristol Jupiter engines. Qantas also built four Puma powered DH.50A models. -ULG was sold in Papua New Guinea in 1935 and crashed at Chimbu on November 10, 1937. Photo from: State Library of Queensland
