Cairns Airport (IATA: CNS, ICAO: YBCS) is an international airport in Cairns, Queensland, Australia. Formerly operated by the Cairns Port Authority, the airport was sold by the Queensland Government in December 2008 to a private consortium. It is the seventh busiest airport in Australia. The airport is located 2.3 nautical miles (4.3 km; 2.6 mi) north northwest of Cairns or 7 kilometres (4.3 mi) north of the Cairns central business district, in the suburb of Aeroglen. The airport lies between Mount Whitfield to the west and Trinity Bay to the east.
The airport has direct flights to 18 international and 30 domestic destinations and many general aviation flights including a number of helicopter operators. Flights are operated to all major Australian cities and tourist destinations, regional communities in Far North Queensland, and a number of international destinations in the Asia-Pacific region with connections to the rest of the world. The airport formed the main base for Australian Airlines prior to its ceasing of operations in June 2006 (the airport remains a major port for parent company Qantas). It is also a base for the Royal Flying Doctor Service of Australia and the search and rescue helicopters of the State Emergency Service. In the 12 months ending 30 June 2013 Cairns Airport had 4.1 million passengers, up 263,532 from the previous year.
