Aviation in Australia began in 1920 with the formation of Qantas, which became the flag carrier of Australia. The Australian National Airways (ANA) was the predominant domestic carrier from the mid-1930s to the early 1950s. After World War II, Qantas was nationalised and its domestic operations were transferred to Trans Australia Airlines (TAA) in 1946. The Two Airlines Policy was formally established in 1952 to ensure the viability of both airlines. However, ANA's leadership was quickly eroded by TAA, and it was acquired by Ansett Transport Industries in 1957. The duopoly continued for the next four decades. In the mid-1990s TAA was merged with Qantas and later privatised. Ansett collapsed in September 2001. In the following years, Virgin Australia became a challenger to Qantas. Both companies launched low-cost subsidiaries Jetstar and Tigerair Australia, respectively.
Overseas flights from Australia to United Kingdom via the Eastern Hemisphere are known as the Kangaroo Route,[1] whereas flights via the Western Hemisphere are known as the Southern Cross Route. Qantas began international passenger flights in May 1935. In 1948, the first commercial flight from Australia to Africa was flown by Qantas, launching what is known as the Wallaby Route.[2][3] In 1954, the first flight from Australia to North America was completed, as a 60-passenger Qantas aircraft connected Sydney with San Francisco and Vancouver, having fuel stops at Fiji, Canton Island and Hawaii. In 1982, a Pan Am airplane first flew non-stop from Los Angeles to Sydney. A non-stop flight between Australia and Europe was first completed in March 2018 from Perth to London.
