The Australian sea lion (Neophoca Cinerea) is one of the rarest species of sea lion in the world and are only found in Western Australia and South Australia. Australian Sea-lions prefers the sheltered side of islands and avoids exposed rocky headlands that are preferred by the New Zealand Fur Seal (Arctocephalus Forsteri) which we see at Cathedral Rocks at Rottnest.
Dyer Island at Rottnest may be small and not that well known but it is the perfect place for a snorkel and is a regular haunt for the local sea lion colony. Located on the south-eastern corner of Rottnest Island in Western Australia, Dyer Island is a family favourite for our charter boat and we are often spoilt to have this secluded spot all to ourselves.
You can anchor directly in front of the island; however, there is only space for a few boats. If you are after an interesting snorkel and maybe a quiet picnic on the boat, then this is it. The waters around Dyer Island are relatively shallow and clear, so the kids feel reassured because they can always see the bottom.
It is rare to visit Dyer Island and not find Australian sea lions sunning themselves and sleeping the day away on the small stretch of beach.
