Botany Bay

Botany Bay is situated in the Greater Sydney region of New South Wales. It is an oceanic embayment with an open entrance.

Botany Bay and its surrounding areas have important recreational, commercial, colonial and traditional heritage values. The bay and its foreshore areas provide opportunities for a variety of recreational activities, serves as Greater Sydney’s main sea port and hosts.

Australia's busiest airport is on the north-western side, with 2 runways that extend into the bay.

First Nations people have lived in the Botany Bay area for thousands of years.

Port Botany was where Captain James Cook made landfall in 1770, signalling the early beginnings of present-day Australia.

Water quality

Botany Bay has not been sampled as part of our monitoring program. We monitor water quality in the Cooks River and the Georges River, the main tributaries to Botany Bay, which were last sampled in 2020.

Local government management

Local councils manage estuaries within their area, unless the estuary is attached to a marine park. This estuary spans multiple local government areas and is therefore managed by Bayside, Sutherland Shire and Randwick City councils.

Protected species

This estuary provides habitat for the protected weedy sea dragon, which is the only known sea dragon in NSW waters.
