The Main Beach area is defined by the narrow coastal dune between the sea and the mouth of the Nerang River. Narrowneck formed the southern boundary and to the north a spit of sand terminated in a break or bar between the Broadwater and the sea. A natural basin for boats existed at the mouth of the river.
Main Beach property has developed as a high rise area only relatively recently and is focused on the exclusive, luxury car-lined Tedder Avenue which is packed with upmarket eateries and boutiques. It has a sense of more permanent residential neighbourhood than other parts of the high rise coastal strip. The restaurants and coffee shops service this use. Most of the apartment buildings along the foreshore are more modest in scale. The isthmus at Narrowneck acts as a natural barrier to the more intensively developed area to the south.
