One of my favourite things about diving in Western Australia is the stunning turquoise water, and the best place to see it is at Rottnest Island.
Located 19kms off shore of Fremantle, Rottnest Island is an easy day trip. Ferry’s travel to an from all day, and once reaching the island you can easily walk around or rent a bicycle for your time on the island.
The best diving at Rottnest is in the deeper waters surrounding the island, unfortunately a little out of reach for shore diving. Dive boats depart from Fremantle for a day on the water at Rottnest and usually include two dives with a fantastic lunch in between.
What makes Rottnest Island different? The limestone typography! It’s a very volcanic sea floor scattered with swim throughs and holes to explore. The warm Leeuwin current runs south down the West Australia coast and brings with it a huge array of marine life. It’s because of this current that you can expect the water temperature to be a little warmer than shore dives in Perth.
Diving through the waters of Rottnest you’ll see cray fish, port jackson sharks, hundreds of bullseyes, schooling ***yellow fish***, Western Australian Dhu Fish, Western Blue Devil, and Grey Nurse Sharks! At times of the year Rottnest has been known to host turtles, manta rays and even a baby whaleshark!
I was lucky to join the Destination WA crew diving at the Opera House dive site – in 35m of water we observed the Grey Nurse sharks in their natural habitat. Have a look at the episode snippet here (spot me with my camera swimming through the cave)
Not a scuba diver? Don’t worry you don’t have to miss out. The snorkelling off the beach on the island is really good – the water is clear and a lot of small reef fish make home in the shallow waters. You can hire snorkelling equipment on the island, or better yet take your own so you know you’ll be comfortable 🙂
If you’re travelling over to Rottnest in the autumn months, make sure you keep your eyes open for Humpback Whales! Families of Humpbacks migrate through the Perth waters over this time of year and are amazing to see.
