Rottnest Island Airport (IATA: RTS, ICAO: YRTI) is a small airport for light aircraft, situated about 800 metres (2,600 ft) from the main settlement at Thomson Bay, Rottnest Island and 19 kilometres (12 mi) northwest of Fremantle.

The airport opened in November 1930 and has been used regularly since then for private and small commercial operations, ferrying workers and holiday makers between Perth and the island.

[2] At one stage, the 32-kilometre (20 mi) Perth to Rottnest flight was the world's shortest scheduled air route.

[4] The service closed in 1961 after concerns about the safety of the ageing aircraft[5] and recurring conflict with the Department of Civil Aviation over minor infringements of regulations.

[11] On 12 November 2006 a light twin engine charter aircraft carrying the pilot and five passengers crashed on the edge of the salt lake adjoining the airport.
