Coolangatta is a coastal suburb in the City of Gold Coast, Queensland, Australia. It is the Gold Coast's southernmost suburb and it borders New South Wales. In the , Coolangatta had a population of 5,948 people. Geography Coolangatta and its immediate neighbouring "Twin Town" Tweed Heads in New South Wales have a shared economy. The Tweed River supports a thriving fishing fleet, and the seafood is a local specialty offered in the restaurants and clubs of the holiday and retirement region on both sides of the state border. There are three hills in Coolangatta: Kirra Hill ( ) at above sea level on the coast, which was named in 1883 by surveyor Schneider (1883) using an Aboriginal word which might mean white cockatoo or fire Greenmount Hill ( ) at above sea level on the coast, which was named for the Greenmount Guest House, operated from 1905 by Patrick J. Fagan, and named after his birthplace in County Meath, Ireland Murraba ( ) at above sea level on the border with New South Wales Point Danger is a headland on the Queensland/New South Wales border (). It was widely believed to be named by Lieutenant James Cook on his 1770 exploration of the eastern Australia coastline in HMS Endeavour, but this is only partially correct. Cook did create the name, but he applied it to another headland further south (now known as Fingal Head). This was confirmed in the 1823 map produced by explorer John Oxley. However a map published in 1831 based on the 1828 survey conducted on HMS Rainbow applied the name Point Danger to the headland north of the Tweed River. So while Cook created the name, he did not assign it to the current location. Rainbow Bay is offshore from the south-east of the suburb (). It was originally called Shark/Sharks Bay until 1926 when the Coolangatta Town Council decided to rename it after HMS Rainbow, a sixth-rate frigate, commanded by Captain Henry John Rous, used in surveys of the area in 1828. There are three neighbourhoods within Coolangatta: Kirra () which takes its name from Kirra Hill Greenmount ( ) named after the guest house Rainbow Bay ( ) named after the bay Point Danger Lighthouse is located on the Point Danger headland (). There are three beaches in the suburb, from west to east: Kirra Beach () Coolangatta Beach () Greenmount Beach () There
