The island group consists of South Muiron and North Muiron islands, which are separated by a deep-water navigable channel and both run in a north-easterly direction, and Sunday Island, which is smaller and lies further east.
The Cod Hole
The ‘cod hole’ runs parallel to South Muiron Island and is one of the most magnificent dives in the Exmouth area. At this reef cleaning station the limestone reef, in deep water, is covered in thousands of golden cardinalfish. Large potato cod are also frequently seen. Many other smaller cod and emperor species gather around divers. Watch for the colourful coral cod and enormous graceful manta rays.
Another spot known as ‘The Spit’ has numerous swimthroughs along a rocky ledge, where divers are enveloped by hundreds of tiny baitfish and may discover a grey nurse shark or turtle sleeping peacefully under a ledge. Large manta rays are also common.
The Gap and The Bastions
Lying between the South Muiron and North Muiron islands, The Gap provides an amazing drift dive over colourful soft corals, hard corals and sponges.
On the western side of the South Muiron Island a rocky outcrop offers an amazing dive to 16 metres. Numerous reef sharks lie under the overhangs and ledges and on top of the ledges, large plate corals sprawl out to capture the available light, providing shelter for colourful reef fish.
Safe not sorry
Remember that there are strong currents at the Muiron Islands and conditions may be unpredictable. It is recommended that you visit with an experienced local charter operator. En route you may see dolphins, pilot whales, dugongs, humpback whales (during the migration season), turtles and other wildlife.
