The best time to dive and the best visibility can be achieved when diving on the high tide after the clean water has been brought in. You should add around 20 minutes to the tide charts for this dive site, and you should get a nice leisurely dive. This site is renowned for strong currents between slack tide, so care should be taken prior to jumping in.
Visibility will range between 5 to 10 metres depending on the tides, recent rainfall, etc. Once you enter the water, swim out about 10 metres until you pass the large yellow bouy. The water here is about 2-3 metres but if you swim in an easterly direction it will soon drop to a depth of 15 metres. Once you reach the wall, head south, keeping the wall on you right. After about 25 metres you will come across a small bubble cave. Avoid the temptation to breath the air as it can be quite stale. Moving along, the wall and the bommies situated away from the wall are covered by all kinds of marine life.
On the return trip, you can swim back at around 8-10 metres depth and examine the life clinging to the wall. The exit point can be found by taking the slope up after bubble cave.
