Dive Site: North Rock

About North Rock

North Rock is a premier dive site located off Broughton Island, approximately 20 kilometers north of Port Stephens in New South Wales, Australia. This protected area within the Port Stephens - Great Lakes Marine Park is celebrated for its healthy marine ecosystems and significant biodiversity, making it a crown jewel among Australia's accessible diving destinations. The underwater topography combines kelpy bommies, distinct rocky ledges, and sandy gutters, creating varied habitats. While the rock appears unremarkable above the water, below the surface, depths range from 5 meters at the top to a median of 14 meters, extending down to 16 meters. This structure offers numerous vantage points for divers to observe marine life. The site is home to a rich variety of marine species, with 12 documented species observations, including numerous nudibranchs. A major highlight is the aggregation of over 30 grey nurse sharks, which find shelter in the natural, cliff-like rock formations. Divers can also encounter Port Jackson sharks and a wide array of other critters thriving within and above the kelp beds. This rich marine life is present year-round, although specific seasonal events can enhance encounters. North Rock is well-suited for beginner divers and offers shore entry options, making it family-friendly. It is a year-round diving location, often dived from Port Stephens. Divers can expect a relatively easy and rewarding experience, exploring the unique underwater landscape and its resident marine inhabitants.
