Three Sisters

Three Sisters is an intermediate dive site at Milln Reef on the outer Great Barrier Reef. This site features three prominent coral bommies rising from 30 meters, creating a dramatic underwater seascape. Each bommie supports its own micro-ecosystem with distinct coral formations and resident marine life. The channels between the sisters create current flows that attract schooling fish, reef sharks, and pelagic visitors. It's considered one of the most scenic multi-bommie dives in the Cairns section.
