Dive-site story
Located off the northern flank of Broughton Island within the Port Stephens-Great Lakes Marine Park, Shark Gutters cuts through rocky volcanic reefs to form submerged channels where pelagic and coastal predators shelter. Sand-bottomed trenches weave between vertical rock walls draped in sponge gardens and kelp, creating natural thoroughfares for large aggregations of sharks.
Cruising alongside aggregating grey nurse sharks patrolling the sandy channels
Rocky gutters layered with encrusting sponges, ascidians, and kelp forests
Encounters with large resident eastern blue gropers and resting wobbegongs
Location

Seasonality
