Operator review of The Sisters' rock profile, lee-side use, and current.
Offshore rocks off Cape Brett with a current-driven canyon dive.
Offshore rocks off Cape Brett with a current-driven canyon dive.
Boat-only, current-sensitive site that is best handled by a Bay of Islands operator.
The Sisters are a pair of offshore rocks off Cape Brett that form a compact canyon-style dive. One side drops quickly into boulder-strewn water while the inshore line is a little easier to read, but the site still suits experienced boat divers. Current and surge can reshape the dive, and the rocks usually hold schooling fish, nudibranchs, perch, scorpionfish and the occasional shark.

Depth Note
Split rock with a canyon around 10m, a seaward drop into the mid-40s, and boulder structure around 30m.
Best Season
Year-round in settled weather.
Typical Conditions
Current and surge are the main variables; the lee side can be workable when more exposed sites are out, but the site still wants a careful plan.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Strong current can be present; plan the dive for conditions and depth accordingly.
Access Restrictions
Boat access only.
Community notes to help plan your visit.
Scuba Diving
Experienced divers can work the canyon and boulder slopes, using the lee side when conditions allow and keeping an eye on current and surge.
Freediving
Not a practical freedive target because the site is deep and current-sensitive.
Snorkeling
Not a practical snorkel target; the main relief is deeper and better handled by scuba.
