Hastings Reef Blue Lagoon - Great Barrier Reef

Long Beach often gets overlooked for its flashy neighbours, but we think that’s a mistake. It sits just east of Piscadera Baai’s entrance, usually meaning calm surface conditions, a real bonus for easy entries. The draw here is that gentle drop-off, a wall that goes down to about 18 metres. You’ll find some lovely sponge formations clinging to the wall, mixed with pencil corals, and the shallow sections are surprisingly pretty. We particularly like the schools of surgeonfish that hang out in the shallows, a silvery flash against the sand. Keep an eye out for sea horses tucked into the coral; we’ve had luck spotting them here. Eagle rays glide past sometimes too, and the reef is home to plenty of common octopuses and blue doctors. Visibility averages around 14 metres, which is perfectly good for taking in the boulder brain coral and sunray lettuce coral formations. This site is a great pick if you’re looking for a relaxed dive with consistent conditions, especially good for newer divers or those who prefer a more leisurely pace.
