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.

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.

Inscription Point offers one of Sydney's most accessible shore dives, perfect for building confidence in open water. You'll enter from the sandy beach and swim out over a shallow reef system that slopes gently to 12 metres, giving you plenty of bottom time to explore at your own pace. The kelp forests here create a distinctly Australian underwater landscape, swaying columns that provide shelter for an impressive variety of marine life. Keep your eyes open for weedy sea dragons drifting among the fronds, one of the site's signature species. You'll likely encounter Port Jackson sharks resting on the sand, along with curious blue groper that often approach divers. Look carefully in the kelp for well-camouflaged boxfish, octopus tucked into crevices, and colourful nudibranchs on the reef. Visibility ranges from 5 to 20 metres depending on conditions and recent weather. The mild current makes navigation straightforward, though you'll need to watch for occasional surge near the entry point and stay aware of boat traffic in the bay. The site rewards careful observation. Giant cuttlefish, moray eels tucked into rocky holes, and the occasional eagle ray all make appearances, while hawksbill turtles patrol the reef.

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.

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.

The Cutting at Farkernell is a wall and cave dive that drops to between 24 and 29 metres, making it strictly advanced territory. Visibility ranges from 10 to 30 metres depending on conditions, and while currents are typically mild, they can strengthen without much warning. The wall and cave structure provides excellent habitat for wobbegongs, Port Jackson sharks, and moray eels tucked into crevices, while southern eagle rays and bull rays cruise the deeper water. Giant cuttlefish, blue groper, and nudibranch add detail to the reef sections, and schools of yellowtail are a regular presence mid-water. August tends to bring the clearest conditions.

Tabbagai Gap combines natural reef structure with artificial reef elements to create a varied dive across 18 to 24 metres of water. Visibility swings considerably, anywhere from 10 to 30 metres, and current can run hard through the gap, so reading conditions before dropping in is essential. The sponge gardens are a highlight, providing dense cover that attracts wobbegong sharks resting on the substrate and Port Jackson sharks wedged into crevices. Weedy seadragons move through the structure alongside eastern blue groper, while nudibranchs and Australian giant cuttlefish reward slower, methodical searches. Surf entry makes a boat the only sensible approach.

Located on the southern tip of Botany Bay, Kurnell snorkeling spot allows the exploration of a unique underwater world, made of seaweed and seagrass. While this environment is well known for hosting seahorses and seadragons (they are nevertheless difficult to spot while snorkeling), Kurnell has even more surprises to offer! While swimming along the shore, you may come across colorful wrasse, octopuses huddled among the rocks, and, sometimes, a stingray resting on the sand.
