It is part of the City of Lake Macquarie local government area. The locality is named for the large number of caves on the nearby coastline.

The traditional custodians of the land were the Awabakal people.

Caves Beach approximately covers 43 km2 (16.6 sq mi). The west side of the suburb is mainly all residential. To the east, there are more shops, cafes and restaurants. To the far east is the beach.

To the north is Swansea Heads and Ham's Beach, named after a family living on a hill behind the Surf Lifesaving Club. The rocky section of Ham's is dubbed Frenchie's Beach by the locals. To the south is Pinny's Beach.

The Plains were covered with grass trees and the Awabakal people went there to collect the resin, used in spear-making. There were campsites at Ham's beach because of the good fishing and availability of a fine-grained quartzite for making stone implements.

Originally, Caves Beach was known as The Plains. After the name was changed to Plains Beach and then Caves Beach. In 1960 it was named Mawson but the community objected and the name Caves Beach was restored in 1965.

The Swansea-Caves Beach Surf Life Saving Club was founded in 1929 by a group of men from Swansea wanting to establish a Surf Lifesaving Club between Swansea Heads and Pinny Beach.

Early surveying for [Land Grants] occurred in 1864 and early subdivisions in 1935. in the 1940s Mr. Mawson, initiated the development of Caves Beach. At one stage he involved a Japanese consortium in a mining venture called Silver Valley Minerals but it failed to develop. The breakwater at Spoon Rocks remains from this venture, constructed to load coal into ships.

In 1958 plans were approved for a new hotel on Caves Beach Rd called The Mawson. The pub was famous and very popular throughout the 60s and 70s and attracted the attention of bands such as [Midnight Oil], [Cold Chisel] and [The Angels] who performed there. The hotel was beloved by the locals but The Mawsons eventually sold the hotel for a reported $1.2million and on 9 October 1981. In 2018 a restaurant called Mawson opened up, with the name being an obvious reminder of the old hotel.

Swansea High School opened at Caves Beach in 1964 and Caves Beach Public School was opened in 1968 beside the high school.
