    StandoutExceptional marine biodiversity

    Bikini Bottom is one of those sites that just feels like home. We love it for its laid-back vibe, perfect for a long, easy dive where you’re not constantly checking your computer. The main draw is that big sand patch around 5-6 metres, ringed by a lovely top reef that slopes gently to about 12 metres. This is where you slow down and really look. Our favourite thing to do here is hunt for the small stuff. We've spent entire dives watching Mottled Jawfish tend their eggs, or spotting a well-camouflaged Plumed Scorpionfish tucked into a crevice. Keep an eye out for those tiny Dusky Blennies peeking from their holes, too. The reef itself might not be dramatic walls, but it’s healthy, with some good stands of Ten-ray Star Coral. It's a fantastic spot for newer divers to build confidence, or for experienced eyes to just chill out and macro-focus. Visibility usually sits around 20 metres, and currents are generally mild, making it a truly relaxing cruise.

    Safety Notes

    Drift dive - carry a surface marker buoy (SMB) and stay with your group. Brief the current direction before entry.
