Australasian Gannets are common throughout the year over inshore waters in eastern, southern and south-western Australia. They breed in noisy colonies, usually on islands or artificial structures, such as beacons. However, a colony at Point Danger, near Portland in south-western Victoria, is situated on a promontory that protrudes from the mainland. There are just two other mainland colonies, both in New Zealand. Gannets forage by plunging headlong into the water from great heights to catch fish in their bills, before resurfacing to eat their prey.
