Cairns

Cairns is considered "the Gateway to the Great Barrier Reef." The city is much smaller than places like Sydney, Brisbane, or Melbourne, however it is still famous due to its proximity to one of the natural wonders of the world. The city is right next to the ocean, however people do not swim in the ocean because of the high prevalence of crocodiles in the area. Instead, the government created an enclosed area of ocean water called the "Lagoon," in the central business district of Cairns.
