The Island’s Ecosystem
Lady Julia Percy Island has a special ecosystem due to its volcanic past and isolation. The rocky cliffs and scrub provide habitat for seabirds such as fairy prions, short-tailed shearwaters and crested terns. These birds make the island a key site for bird conservation in Australia. The surrounding waters are home to marine life, an important habitat for Australian fur seals often seen on the island’s rocky shoreline. The underwater environment is just as diverse, with kelp forests, colourful reef systems and various fish species, all contributing to the island’s high marine biodiversity. As part of the Island Wildlife Reserve, the area is managed by Parks Victoria to protect the island’s flora and fauna.

The island is of great cultural significance to the Eastern Maar & Gunditjmara people, who have been using it as a sacred site for thousands of years.
