Much of Woollahra's native animal biodiversity has been lost to development, road mortality and attack by domestic and feral pest species. Some species still live on however.

Mammals include brush-tailed and ring-tailed possums, larger reptiles include the blue-tongue lizard and eastern water dragon, and there are still species of frog inhabiting watercourses, including the leaf-green tree frog, brown-striped marsh frog and the eastern froglet.

Penguins still visit our bays, and the fish, crabs and crustaceans which inhabit our foreshores are the same species our traditional Indigenous land owners hunted for thousands of years.

The beautifully patterned eastern quoll, now only found in Tasmania, inhabited Woollahra until the mid 1960s and there is still available habitat for this species, if it were protected from dog and cats. Suitable habitat and food supply for bandicoots and other small native mammals is also still available within Woollahra.

Some species have been lost, but perhaps not forever!
