That was one of the good things about the place, being able to walk the reef. Not sure but I was once told it is one of the very few places where the reef comes to the shore.
I was there at a time of zero tides and my mate was an avid shell collector, in fact he had one of the best shell collections in Australia, and we collected many shells from the area.
The other thing you could do was find pools at low tide and hand spear coral trout.
Marvelous place.
