Cairns was founded in 1876 and was named after William Wellington Cairns, the Governor of Queensland between 1875 and 1877. The city was formed to serve the miners heading for the Hodgkinson River goldfield; however, it fell into decline when a more accessible route was identified from Port Douglas. Cairns later developed into a railhead as well as a major port for exporting gold and other metals, sugar cane and agricultural products from the Atherton Tableland region. The site was gradually cleared of the swamps, and the sand ridges were filled with dry mud and ballast from Edge Hill quarry.
Cairns has grown by an average of 2.3% every year over the last decade. The reasons for this include the fact that the tourism industry has remained consistently robust over the years, and this has created a high number of job opportunities within the city. Cairns is a trendy tourist destination, and this is due in part to its tropical climate and the fact that the Greater Barrier Reef – one of the seven natural wonders of the world – can be found here. The city attracts more than two million visitors every year, making it one of the globe’s top tourist hotspots. A relaxed living style has also attracted many retirees from all over the world.
