The Kangaroo Route is a term coined by Qantas, referring to the commercial passenger air routes flown between Australia and the United Kingdom via the Eastern Hemisphere.
The route has been operated since 1934, but found its name in 1944 from the unique mode of travel of the kangaroo, as the route's "hops" were reminiscent of a kangaroo's hops both use to cover long distances. The term is trademarked and traditionally used by Qantas, although it is often used in the media and by airline competitors to describe all Australia to United Kingdom flights.
In addition to Qantas, by 2003, over 20 airlines operated routes connecting Australia and the UK, including: Air New Zealand, British Airways, Cathay Pacific, Emirates, Japan Airlines, Lauda Air, Malaysia Airlines, Thai Airways, United Airlines and Singapore Airlines, with most involving a change of plane. As of 2023, only two airlines continue offer through direct flights (not requiring passengers to change plane en route): British Airways and Qantas.
Qantas commenced operating non-stop flights from Perth to London with Boeing 787s on 25 March 2018. This ended the era of the continents of Europe and Oceania not being connected by non-stop flights, marking the first time that all of the world's continents, excluding Antarctica, are connected by non-stop flights.
Qantas operated the Australian part of the Kangaroo Route for 9 years before coining (and later trademarking) the name.
After starting airmail operations between Brisbane and Singapore in 1934, Qantas began operating passenger flights connecting Brisbane to Singapore in 1935 following successful awarding of the Australian government's tender.
After disruption to the route due to the emerging hostilities of World War II, the connectivity was famously restored by Qantas with its "Double Sunrise" service connectivity between Perth and Ceylon on the Indian Ocean Route with Catalina flying boats in 1943.
