Byron Bay is a beachside town located in the far-northeastern corner of the state of New South Wales, Australia. It is located 772 kilometres (480 mi) north of Sydney and 165 kilometres (103 mi) south of Brisbane. Cape Byron, a headland adjacent to the town, is the easternmost point of mainland Australia. At the 2011 census, the town had a permanent population of 4,959. The town is in turn the nucleus of Byron Shire, which had 29,209 residents.
The local Arakwal Aboriginal people's name for the area is Cavvanbah, meaning "meeting place". Lieutenant James Cook named Cape Byron after Naval officer John Byron, circumnavigator of the world and grandfather of the poet Lord Byron.
