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.

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.

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.

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.

Bare Island offers something rare for beginners: a shore dive with genuine underwater variety right off the beach at La Perouse. You'll enter from the protected western side and immediately find yourself surrounded by various reef species exploring the rocky ledges and kelp beds. The site works well as a shallow reef dive in 5 to 10 metres, perfect for building confidence, but more experienced buddies can venture deeper to 21 metres along the island's walls. The real attraction here is the system of swim-throughs and small caves cut into the island's base. These aren't challenging overhead environments, but they do require awareness and good buoyancy control. Variable currents keep things interesting, and you'll occasionally feel surge pushing through the passages. Visibility ranges from 5 to 15 metres depending on recent weather and tides. Because you're diving around an island structure, conditions can change between the sheltered and exposed sides. Start shallow, get a feel for the current, and only explore the swim-throughs when you're comfortable with your buoyancy. Keep an eye on your air and your buddy, especially near any structure where entanglement with kelp is possible.

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.

Container Wall sits in the easy shallow waters of Botany Bay, running as a wall with an adjacent cave section that gives the dive a bit more structural interest than a flat reef. Depths stay between 8 and 9 metres throughout, making it a comfortable pick for intermediate divers who want to focus on technique and observation rather than managing a profile. Visibility swings considerably, anywhere from 5 to 20 metres depending on conditions, so timing your visit matters. Mild current keeps things manageable. Various reef species populate the wall, and the cave warrants a careful look inside. Boat traffic in the area means staying aware of your surroundings at the surface.

The Tribars is a shore entry wall dive off New South Wales that works best as a drift, letting the mild current carry you along the structure at a consistent 12 metres. Visibility runs between 3 and 10 metres depending on conditions, so timing your dive matters. The wall hosts a variety of resident reef species, and the format rewards a relaxed, observational approach rather than covering ground actively. Boat traffic is an ongoing hazard here, so surface less in the channel and always deploy a surface marker buoy before ascending. Check locally for current facility availability before heading out.
