Kogarah took its name from Kogarah Bay, a small bay on the northern shore of the Georges River. The suburb originally stretched to the bay but has since been divided up to form the separate suburbs of Kogarah Bay and Beverley Park.
Kogarah has a mixture of residential, commercial and light industrial areas. It is also known for its large number of schools (including primary school, high school and tertiary education) and health care services (including two hospitals and many medical centres). The NRL side, St George Illawarra Dragons have their Sydney office based at nearby WIN Jubilee Oval, often referred to as Kogarah Oval. Kogarah features all types of residential developments from low density detached houses, to medium density flats and high density high-rise apartments.
