Scawfell Island is an uninhabited gem in the Southern Whitsundays, fringed by coral gardens and rocky edges that come alive with tropical fish. The most popular snorkeling site is Refuge Bay, a sheltered anchorage at the island's western end offering calm, clear waters. The fringing reef here presents an unusual underwater landscape of patterned hard corals and swaying soft corals in sandy shades, rather than towering coral heads. For wreck enthusiasts, the historic Llewellyn shipwreck lies off the island's shores, discovered in 1997 and now encrusted with soft corals, attracting large schools of fish, coral trout, and sea turtles. Crystal-clear visibility and easy access from the beach make this a rewarding spot for snorkelers seeking uncrowded, pristine reefs away from the main Whitsundays tourist trail.

Small white-tip reef sharks have been reported circling in the shallows. Generally non-aggressive but can startle snorkellers.
Low risk: Shallow reef and coral channels
The reef near Refuge Bay has some shallow areas and channels that can be tricky to navigate; at low tide reef flats sit just below the surface.

Low risk: Reef Sharks
White tip reef sharks have been sighted in the area, though they are not typically aggressive.
Low risk: Shallow Reef Flats
Shallow reef flats at low tide can be just under the surface, making it difficult to swim over without scraping.
