About Waterfall Bay

Suicide Cliffs is made up of reef and walls good to do in conjunction, and optimal in a northerly. Studio Two is the perfect novice spot. Kelp and seadragons being the main features here. Dragon City as the name suggests - weedy sea dragon capitol. Horseshoe Cave stunning cave to explore when the ocean is flat, enter on the left the view is incredible. Dogleg Cave has lots of swim throughs and crevices and another section leading to a bigger cave don't go in unless the water is very flat this isn't a joke. When you head back on this one do it along the cliff back to the small cave over the boulders lots to see! Cathedral Cave ranks on the top of Tasmania's cave diving list needs to be dived more than just once to be fully appreciated. Knome Cave and the Bluff enter from the Cathedral's mooring. The 21m depth can be dived by all grades but watch the vis it can be really bad and don't go in too far in a swell its gets shallower the deeper you venture and you will get stuck. Headbanger Cave and the Dragons Lair can be dived in a northerly when the Cathedral is weathered out - lots of weedy sea dragons. Patterson's Arch: Great dive for everyone - canyon and baby cave with amazing walls -18m deep.

Dive Site Hazards

  • Hidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.

  • Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.

  • Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.

  • Remote Silt Disturbance — Silt can be disturbed metres away from the source.

  • Rapid Stress Escalation — Stress can increase sharply when visibility or navigation degrades.

  • High Cognitive Load Navigation — Complex passages increase mental workload even on a line.

  • Unstable Visual Ascents — Relying on wall visuals can destabilise ascents.

  • Gradual Depth Creep — Lack of visual bottom reference can cause unnoticed descent.

  • Unsignalled Downcurrents — Downcurrents can form without visible indicators.

  • Bubble Trapping Under Overhangs — Rock overhangs can trap exhaled bubbles, reducing visibility and causing disorientation.

  • Reflected Surge Patterns — Surge reflecting off rock faces can create irregular and unpredictable water movement.

  • Current Funnel Effect — Narrow gaps between rocks can accelerate water flow unexpectedly.
