Observatory is a shallow artificial reef sitting in just 2 to 6 metres of water, making it an ideal first dive for beginners. The structure has attracted a settled community of marine life including grouper, sweetlips, clownfish, and the occasional wobbegong shark resting on the bottom. Stingrays and reef sharks pass through regularly, and if you slow down and look carefully, nudibranchs are tucked into the reef's quieter corners. Visibility ranges from 5 to 30 metres depending on conditions, and the current stays mild. Watch for jellyfish, particularly in warmer months, and check conditions before entering.
