Australia Zoo made a joke on its Facebook page after a second woman in a week was bitten by a wild snake at the venue.

The Queensland zoo posted "oops ... She did it again!" when a woman aged in her 30s was taken to hospital on Monday after she stepped on a small green tree snake, a week after a woman in her 20s was bitten by the same species in the park's wetlands area.

"Today a visitor at Australia Zoo didn't see a small, non-venomous green tree snake on the pathway and received a bite to the leg after accidentally stepping on it," the Facebook post said.

"Following protocol, the guest is now being checked over at the hospital.

"P.S. Snake is fine too."

The woman was taken to Caloundra Hospital after being bitten about 1.30pm.

After the first woman was bitten last Monday, Australia Zoo issued a statement and said the green tree snake was a common occurrence in the wetlands "as it is the perfect environment for their favourite food, frogs".

That was the first time a guest had been bitten by a snake in the zoo's 46-year history.

Australia Zoo is on Queensland's Sunshine Coast and was established by wildlife warrior Steve Irwin, who died in 2006 from a stingray barb.

Green tree snakes usually live along the north or east coast of Australia and often lurk within gardens. They have no fangs or venom and can grow up to two metres.

According to the Queensland Museum, they are usually green but sometimes black, blue or yellow.

Green tree snakes in Queensland's southeast are usually green with bright yellow throats.

Bites are usually harmless to humans as they only have small teeth.
