3 mile Bommie is an offshore reef off The Entrance built around a broad bommie complex with shallow reef, caves, and channel features. It suits divers who want a boat day with lots of marine life, varied terrain, and a site that rewards steady pacing and good buoyancy more than heavy exertion. Boat access and changing sea conditions are part of the normal setup, so it works best as a relaxed offshore day rather than a rushed drop-in.

Scuba Diving
A boat run gives access to the reef, caves, and channels, with the best diving coming from a steady pace and clean buoyancy.
Freediving
Not a dedicated freedive site; the offshore profile and variable visibility suit scuba better.
Snorkeling
Snorkeling is limited to the shallower reef edge and is not the main use case.
