Shelly Beach can be well explored in a couple of dives. One dive can be spent swimming up the northern peninsula, south into the bay and then east back towards the beach as you try to track down the submerged motorcycle. Keep an eye out for weedy sea dragons amongst the kelp.
Dive two could be well spent as a slow swim alongside the promenade, towards fairy bower before heading north and back I to the beach through the bay. Swim through the maze of boulders and soar over the fields of sea grass.
