Bellambi Point is located at Bellambi, Wollongong. Bellambi Point is a beach used for many recreational activities such as surfing and fishing. Bellambi beach has sewer works nearby and an outlet pipe crosses the northern end of the beach, with a vegetated dune to the south.
There are several rocks in the waves due to rocks and reefs reducing waves to less than 1 metre, combined with the sewer, potentially hazardous for beach users such as swimmers or surfers.

Bellambi Point is a dune-capped shale point, which extends 600 m seaward as Bellambi Reef. Either side of the point are two rock and reef-dominated beaches. The northern Bellambi Harbour beach is a narrow 400 m long strip of high tide sand fronted by 50 m wide rock flats grading into reefs which extend 200 m offshore. It faces northeast and is sheltered by the point and reefs, as well as by an attached breakwater, which shelters a large boat ramp and car park at the eastern end. It is backed by an access road, parks and the Bellambi sewer works.
Bellambi Point beach commences at the tip of the point and trends southwest for 900 m; the first 400 m in lee of shallow reefs, with a southern 400 m long section open to the sea and linking to a salient in lee of a low reef called Sandspit Point.

The aim of the Bellambi Point field study is to use tools and techniques to examine abundance and distribution of species across the rock pools of Bellambi point. To measure abiotic features in ecosystem using the appropriate instruments and to relate the data to organism distribution. To also identify the variety of marine species, and to analyse and construct a food chain/ food web and relate the information to the abundance of organisms.
