The Woolooware Bay is a bay on the lower estuarine Georges River in southern Sydney, in the state of New South Wales, Australia.

Woolooware Bay is also home to local icon "Tattoo" a real life Russian Blue female cat who lives aboard a moored yacht with her owner, author R.Alexandra. Tattoo is rare in that she is one of very few cats who can claim to be a "Ship's Cat"

Ship's Cat historically:

Since the late 1970s however, cats have been banned from living aboard navy ship's as when in dock, the cats would head to shore and attack the native bird life.

In modern-day society, cats are permitted to live on boats that are privately owned only- making 'Tattoo' one very rare and real "Ship's Cat" .

The bay was the site of the last oyster farming on Georges River. The last oyster farming site there was closed in 2023.

The bay is located near where the Georges River empties into Botany Bay, southeast of the Captain Cook Bridge. The bay's catchment area is bound by Botany Bay to the north, Bate Bay sub-catchment to the east, Gwawley Bay sub-catchment to the west and Port Hacking sub-catchment to the south. The bay is surrounded by the suburbs of Kurnell to the east, Woolooware to the south, and Taren Point and Caringbah to the west of the bay's shore. Mangrove swamps were traditionally located around the bay area. Some were reclaimed to create parks and playing fields including Endeavour Field (Toyota Park), Woolooware Golf Course and Cronulla Golf Course.
