Fish Soup is a small but intensely productive point on North Solitary Island, named with typical local bluntness for the sheer density of fish that pack into one compact area here, drawn by the way the point channels current and creates a feeding and shelter zone in what is otherwise open, current-swept water. Wooli Dive Centre, the only operator with regular access to the site, is candid that it is not always diveable — the same current that makes the fish life so spectacular can also make the site unworkable on a given day — but rates it as well worth the wait when conditions line up. When the site is on, divers report an almost overwhelming concentration of fish in a small area: large schools of bullseyes, sweep and trevally pack into the lee of the point, kingfish and mulloway move through hunting the baitfish, and grey nurse sharks are seen here as they are elsewhere around North Solitary Island, using the current-swept structure in much the same way they use the gutters at South Solitary Island further south.

Turtles pass through the area as well, and the general reef structure — rock ledges and low gutters in 8 to 22 m — supports typical resident species even when the current is too strong for the big schooling spectacle to be at its best. Because Fish Soup depends so heavily on getting the tide and current right, it is usually worked into a longer day at North Solitary Island alongside the more reliably diveable Anemone Bay, with the operator making a call on the day about which sites are workable. The site sits within the same 75-minute-each-way boat commitment from Wooli as the rest of North Solitary Island, and divers should be comfortable with moderate current and a negative or fast entry if conditions demand it, since Fish Soup's appeal is inseparable from the current that creates it.

Wooli Dive Centre is the only operator serving this section of coast and departs from the Wooli River wharf in the small village of Wooli, reached via Wooli Way off the Pacific Highway/Grafton-Wooli Road. The river mouth has a shallow, shifting bar that the operator's purpose-built jet-propulsion vessel (able to run in very shallow water) is specifically equipped to cross; private trailer boats should not attempt this bar without strong local knowledge. From the wharf it is roughly 25 minutes to North Solitary Island's southern sites and up to 90 minutes to Pimpernel Rock in the north of the marine park, weather dependent.

Wooli Dive Centre requires a minimum group size (around six divers) to run a charter to the more remote sites.

North Solitary Island and Pimpernel Rock sit fully in the open ocean north of the more sheltered Coffs Harbour grounds, so trips depend on a genuinely settled weather window — under about 1.5 m swell and light-to-moderate winds — and are cancelled more often than the South Solitary Island trips run from Coffs. The Wooli River bar itself is shallow and can be dangerous in a big swell or a strong outgoing tide; the dive centre's shallow-draft, high-powered vessel is built specifically to manage it, but the bar can still close the operation down on a bad day. Visibility offshore is normally excellent, in the order of 15-30 m, but summer brings warmer water (up to 25°C) with more current from the East Australian Current, while winter is cooler (down to about 18-19°C) but often calmer.

Cyclone-influenced swells from the Coral Sea can affect this coast in late summer/early autumn even without a direct cyclone hit.

Descend directly onto the point, hold position in the lee of the rock structure to observe the fish schools rather than swimming hard against any current, and work the edges of the current line where the density of fish is greatest before ascending.

Wooli Dive Centre includes Fish Soup on North Solitary Island trips when conditions and the state of the current allow; it is described by the operator as not always accessible.
