Petaj is a boat-access Milln Reef site with bommies, a sandy slope, and mild-current outer-reef conditions.
About Petaj
Petaj is a broad outer-reef bommie site on Milln Reef, with a shallow sandy slope, room to settle in, and enough structure to make a slow, readable circuit. It works best as a relaxed boat dive for divers who want turtles, reef sharks, barracuda, and plenty of macro subjects around the bommies and swim-through features, with the cleanest runs on calmer days.
