This purpose-built shipwreck is one of Australia's best-known snorkelling spots. Back in 1963, fifteen boats were deliberately sunk off Moreton Island, creating both a break wall for small vessels and an appealing new home for sea creatures. 

Just off Amity Point Jetty — the northernmost point of North Stradbroke Island — is a series of rock walls, where all sorts of marine creatures gather to feast and socialise. 

Once a quarantine station for people with leprosy, Peel Island — named Teerk Roo Ra National Park since 2007 — is now a serene natural haven frequented by sailors and sea kayakers. 

In the mid-80s, the Southport Seaway was created to help vessels safely enter Moreton Bay and the Gold Coast Broadwater from the Pacific Ocean. This involved building two rock walls, which now offer adventures a-plenty for snorkellers. 

Mudjimba Island (Old Woman's Island) lies 1.2 kilometres off the mainland, directly west of Mudjimba Beach. Unlike most other reefs on the Sunshine Coast, its is just three metres below the surface, which makes for perfect snorkelling.
