In the 2021 census, the suburb of Main Beach had a population of 3,998 people. Historically, the Main Beach area was a narrow strip of coastal sand dunes separating the mouth of the Nerang River from the Coral Sea. Narrow Neck formed the southern boundary and to the north was a long sand spit terminated by the bar between the Broadwater and the sea. This created a natural basin for boats at the mouth of the river protected from the sea by the Main Beach area.
