Carnac island is home to Australian sea lions, bottlenose dolphins and a large range of marine bird life and is perhaps the best location for snorkelling in Perth. It is particularly noted for the abundance of snakes, particularly tiger snakes, which live there. For this reason, very few people venture there. There is no permanent fresh water, providing a challenge for the animals that live there. The origins of the tiger snake colony has attracted significant debate and research into how that species has adapted to a harsh island habitat.
Carnac is classified as an Important Bird Area because it supports a large colony of the vulnerable fairy tern, as well as small numbers of other nesting seabirds,
All Sea Charters travels to Carnac Island everyday from Fremantle aboard Tradewinds III. Here you can partake in a multitude of activities ranging from Eco Tours of the Island to a full day Corporate Charter where your guests can have a good time on the boat or swim / snorkel in the waters around the Island.
