Boat-accessed, overhead-style swimthrough that rewards calm water, clean trim, and a slow read of the tighter section.
About Matts Crack
A surface-open crack in the Poor Knights with a bright blue interior, narrowing walls, and strong silhouette potential for photographers. The route is easy to follow but still feels like an overhead-style swimthrough, so it suits calm water, steady buoyancy, and a careful pace through the tighter section. It is best run as a boat dive when the skipper can pick a settled window.

Local Intel For Matts Crack
Community notes to help plan your visit.
Scuba Diving
The site is best as a guided swimthrough: follow the crack from the open end, keep your trim centered, and treat the tighter sections as a visual pass rather than a place to linger.
Freediving
Not a freedive-first site; the overhead-style crack and boat logistics make scuba the better choice.
Snorkeling
Not a snorkel-first target. The main feature is underwater, so snorkelers will get much less from it than scuba divers.
