Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Defined by its distinct bottom topography, Grey Nurse Gutters, locally known as Shark Gutters, features channels radiating out from South Solitary Island's shoreline. These natural formations vary in depth from 10 meters (33 ft) to 18 meters (59 ft), presenting diverse exploration opportunities for certified divers.
A primary mooring typically sits at 12 meters (39 ft), serving as a central starting point for dives and allowing immediate access to key features. Most plans involve heading north from the mooring to explore deeper sections, which can extend to 23 metres (75 ft) and incorporate a small wall feature, offering a different profile. Returning toward the island, divers navigate through progressively shallower areas, encountering the main shark gutter.
It leads directly to the island's shore and narrows significantly, culminating in a large boulder. A swim-through opportunity into a small, dead-end gully is offered by this particular boulder, providing a brief, intimate encounter with the site's geology.

Dive Experience & Conditions
Conditions at Grey Nurse Gutters typically favor divers comfortable with a structured environment, characterized by sand gutters, rocks, and boulders carving the seabed. Divers typically begin near the mooring, which sits at approximately 12 meters. Heading north from this point leads to deeper sections, where a maximum depth of 23 meters can be reached along a small wall. Navigating westward then turning south brings divers into progressively shallower water, typically around 10 meters. Here, a primary shark gutter unfolds, leading right up to the island's edge where waves may break overhead. Entering the narrowest part, a large rock presents a swim-through into a small gully. Exploring beyond this confined passage into the island's interior is only feasible on exceptionally calm days.
Dive Difficulty & Safety Guidelines
Grey Nurse Gutters is accessible to divers holding Open Water certification, with opportunities for those with Advanced Open Water to explore deeper sections more thoroughly. Given the site's natural topography, including gutters and potential swim-throughs, having good buoyancy control is beneficial. While specific hazards are not consistently reported, always be aware of surrounding conditions, particularly when exploring the narrower sections of the gutters. For those interested in marine life interaction, the site also supports an Aware Shark Conservation Diver specialization. Always dive with a buddy and follow standard safe diving practices, especially when navigating the more structured underwater environment near the island.
