Gunnamatta Beach is an exposed, high energy beach with a wide, rip dominated surf zone. It is located in the Mornington Peninsula National Park and is part of the 30 km long sandy and rocky coast that extends from Cape Schanck to Point Nepean. The Gunnamatta section is 3 km long, with extensive intertidal calcarenite reefs and rocks forming the boundaries, with some smaller reefs on the beach and in the surf. Truemans Road runs out through the dunes to the beach, where there is a large car park and the surf lifesaving club.
The beach faces south-west, exposing it to high westerly winds and waves. The waves average 1.9 m and combine with the medium sand to produce a 150 m wide single bar surf zone. The bar is cut by strong rips every 300 m, together with additional permanent rips next to major reefs and rocks. The rips intensify around low tide.
The Gunnamatta Surf Life Saving Club was founded in 1966. This is a very hazardous beach, with an average of 113 rescues a year, second only to its neighbouring Portsea Beach.
