Most divers at Rapid Bay perform the usual ritual of crossing the sand from the new jetty to the old before really starting to pay attention to their surroundings.

Granted, the old jetty is certainly the draw card here but take the time instead to head off in a different direction, over the seagrass beds and it is an entirely different experience.

The seagrass is home to all sorts of interesting critters most of which you have to look carefully for as they hide among the grasses but not the leatherjackets.
