By-Pass Reef sits in deeper water off New South Wales, running to 30 metres with visibility that can swing anywhere between 5 and 20 metres depending on conditions. Moderate current is the norm here, but it can strengthen considerably, so solid buoyancy control and situational awareness are non-negotiable. The reef rewards careful exploration: sponge gardens dominate much of the structure, and the site draws an impressive cast of sharks including wobbegong, Port Jackson, and nurse sharks resting along the bottom. Eastern blue groper work the reef in their unhurried way, nudibranchs reward close attention, and Australian giant cuttlefish make appearances worth slowing down for.

Pistol Crack is a boat-access wall and cave site off New South Wales that rewards experienced divers with complex topography and a solid roster of temperate marine life. Depths run from 5 to 30 metres, and visibility swings between 5 and 25 metres depending on conditions. Moderate current, surge, and occasional swell make situational awareness essential throughout the dive. Gorgonians and sea sponges colonise the wall faces, while wobbegong and Port Jackson sharks tend to occupy the cave recesses and ledges. Australian giant cuttlefish, eastern blue groper, and kingfish work the mid-water, and nudibranchs reward anyone who slows down and looks closely at the substrate.

Dees Ditch is a shore entry reef and kelp forest dive in New South Wales that rewards divers who know how to read conditions. Depths run from 10 to 23 metres, and visibility swings considerably between 3 and 15 metres, so timing matters. Moderate current is the norm, with surge adding another variable to manage. The site holds a solid mix of temperate marine life including Port Jackson sharks, wobbegong sharks, and the occasional nurse shark resting on the bottom. Weedy sea dragons move through the kelp, while octopus, nudibranchs, Australian giant cuttlefish, eastern blue devilfish, gorgonians, and colourful sponges fill out the reef structure.

Henry Head is a boat dive combining reef, wall and drift diving along a site that rewards divers who read the conditions well. Depths run from 12 to 26 metres in the deeper sections, with visibility ranging widely from 3 to 25 metres depending on the day. Moderate currents can strengthen without much warning, so staying aware of your position matters here. The walls and reef structure are draped in sponges and sea squirts, and this is a reliable spot to find weedy sea dragons, red Indian fish and the striking eastern blue groper. Cuttlefish, old wife, morwong and schools of yellowtail round out a solid temperate reef encounter.

Dragons Lair earns its name from the weedy sea dragons that pick their way through the reef, and spotting one is the main draw for most divers here. The site runs from the shallows down to 26 metres, giving you room to explore at different depths depending on your air and interest. Visibility ranges considerably, from a murky 5 metres up to a clear 25 metres, so conditions vary by season and swell. Moderate current is typical, though it can strengthen, so keep an eye on it throughout your dive. Blue groper, giant cuttlefish, wobbegong sharks, and Port Jackson sharks round out a genuinely interesting mix of temperate reef species.

The Leap is a wall and reef dive with genuine drift potential, running from the surface down to 23 metres where deeper sections remain largely uncharted. Moderate current keeps conditions honest, and visibility swings between 3 and 15 metres depending on conditions, so timing matters. The marine life here rewards patience: weedy seadragons, pot-bellied seahorses, and pygmy pipehorses turn up for those who slow down and search the structure, while giant cuttlefish, wobbegongs, and Port Jackson sharks represent the larger residents. Bull rays, blue groper, anglerfish, and octopus round out a genuinely varied roster. Surge, entanglement risk, and depth demand solid buoyancy control and situational awareness throughout.

Cape Solander delivers the wild side of Sydney diving, where the Tasman Sea meets Botany Bay's southern headland. This exposed shore dive drops from 4 to 26 metres across a dramatic boulder field and rock walls that attract serious pelagic action. Moderate currents keep the water moving, bringing visibility between 10 and 30 metres and drawing in marine life you won't find in sheltered Sydney sites. Between June and October, humpback whales pass close enough to hear their songs underwater. Year-round residents include wobbegong sharks tucked under ledges, Port Jackson sharks cruising the reef, and southern eagle rays gliding over the sand channels. Look carefully in the kelp forests for weedy sea dragons, while blue groper and moray eels patrol the rock crevices. Giant cuttlefish make appearances during breeding season, and bull rays work the deeper sections. The surge can be significant on bigger swells, and the entry requires confident rock scrambling with full kit. This is challenging diving that rewards experience with encounters you'll struggle to find elsewhere along the New South Wales coast. The combination of depth, current, and exposure means proper planning and conservative profiles are essential.

Yena Extension is the deeper counterpart to the main Yena site, dropping to 23 metres along a wall structure that rewards intermediate divers willing to push beyond the shallows. Depths run from 15 to 23 metres, so you'll want to keep an eye on your air and bottom time. Visibility ranges from 5 to 20 metres depending on conditions, with the clearer days offering a proper look at the reef and wall. Various reef species make their home here, and the absence of current means you can take your time working the wall without fighting the water. Access is by boat, and boat traffic in the area is the primary hazard to stay aware of during ascents.
