Cairns City, QLD
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Cairns is a tropical city on the far north Queensland coast, the main hub for the region and the gateway most visitors use to reach the Great Barrier Reef and the Daintree Rainforest. It stands on the country of the Gimuy Walubara Yidinji people, whose name for the area is Gimuy. The town was founded in 1876 as a port to ship out gold from inland fields, and was named after William Cairns, then governor of Queensland. After serving as an Allied base in the Second World War, it grew into one of Australia's busiest tourist destinations, especially once its international airport opened in 1984. Its economy now leans heavily on reef and rainforest tourism.
