Meet the site

Blue Holes is listed by Ningaloo Whaleshark Swim (whalesharks Exmouth) among west-side sites with caves, swim-throughs, huge bommies or walls, and diverse hard and soft corals. The name suggests deeper holes in the reef that appear blue from the surface.

Site-specific published detail is minimal. Holes in the outer reef typically concentrate fish and offer undercut walls and overhangs, with reef sharks, turtles and rays common. Treat depths as indicative.

About the west side: Ningaloo is a fringing reef, and the west side of North West Cape is where the reef faces the open ocean beyond the lagoon. Only a handful of boats dive it, launching from Tantabiddi, and much of it is rarely visited. Topography ranges from shallow cracked reef and ledges near Tantabiddi Passage to surge channels, bommies and walls further out, with 'caves, swim-throughs, huge bommies or walls, and a truly diverse range of hard and soft corals'. Whale sharks, mantas and humpback whales are seasonal visitors, and humpback song is commonly heard underwater in winter. The 2025 marine heatwave caused significant coral mortality in northern Ningaloo, so expect some dead or recovering coral. A typical west-side day combines two sites chosen by the skipper on the morning, with lunch on board inside the lagoon; because swell and wind decide everything, divers visiting Exmouth for a week should book early in their stay and keep a back-up day. The same boats often snorkel with whale sharks, mantas or humpbacks in season, so a west-side dive day can deliver megafauna on the way out or back.

Some details in this record need confirmation. Check the source information and speak with a local operator.

Topics flagged by the stored research

These are questions prompted by the existing notes, not a verified or complete hazard assessment.

Current and timing
Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
Water movement
Ask how swell and local exposure affect the proposed entry, exit and route.

Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
