About this park
Carnac Island Nature Reserve is a picturesque limestone island 10km off Fremantle. What makes the island stand out from the crowd are some rather unusual visitors that pop in now and then.
Australian sea-lions use the island as rest area, before slipping back into the ocean to feed. This animal is the rarest sea lion in the world, and the only type found in Australia. See them basking on the beach and frolicking in the water. Do stay safe though and keep your distance. Despite looking cute and cuddly, sea lions are large creatures and can be aggressive if they feel threatened.
Talking about staying safe, when going onto the island visitors should not leave the beach and venture inland. Carnac has a significant population of tiger snakes, one of the world’s most deadly snake species. It is one of only two islands in Western Australia where tiger snakes are found.
Bird watchers will love the variety of seabirds here. Little penguins, wedge-tailed shearwaters, and crested terns are just some of the species that nest on Carnac. While birdwatching, please remember to stay clear of any nesting areas to avoid disturbing the birds.
Day tripping by boat is the best and only way to visit the island. You don’t have to go onto the island to enjoy its beauty just sit back and watch the activity from your boat or kayak. You can also explore underwater by swimming, snorkelling, or diving.
Plan when to visit. Read this safety information about swimming, paddling, kayaking, snorkelling and diving. Consider travelling with a personal location beacon (PLB). In the event you need to be rescued it could save your life!
Avoid venturing inland due to the significant population of tiger snakes.
Keep your distance from sea lions as they can become aggressive if they feel threatened.
