Moon Island - Sydney & New South Wales

Proco House Reef in Halmahera is a surprisingly rich spot, right off the resort jetty. We've often found ourselves dropping in here for a relaxed afternoon dive, especially good for shaking off travel fatigue. It's not a deep dive, maxing out around 22 meters, with visibility typically hitting a clear 24 meters. The reef itself is heavily overgrown, creating plenty of nooks and crannies to explore. You’ll weave through schools of fusiliers, their silver bodies flashing, and we’ve spotted everything from little Blackbelly Pygmygobies to a couple of those elusive Largemouth Triplefins if you have a keen eye. The safety stop under the jetty is a nice touch, offering a final look at the critters clinging to the pilings before surfacing. It’s a solid pick for a low-key dive where you still want to see some action, a good site for building confidence or just unwinding.
