Voo Doo is a boat-accessed wall and cave site off New South Wales that rewards experienced divers willing to push into deeper water. The dive runs to 24 metres, where the wall and cave structure demand solid buoyancy control and a genuine awareness of the overhead environment. Visibility ranges from 10 to 20 metres, giving you a decent read of the terrain. Despite no current being typical, the listed hazards of strong currents and depth mean conditions can shift, so check locally before gearing up. Various reef species work the wall, and the cave sections add a navigational dimension that keeps the dive engaging throughout.

Osborne Shoals is a reef and wall site off New South Wales that rewards experienced divers with a solid mix of pelagic and benthic life across 11 to 24 metres. Moderate current runs across the structure consistently, so drift technique matters here. Visibility ranges from 5 to 12 metres depending on conditions. The shark life is a genuine drawcard, with Port Jackson, wobbegong and nurse sharks all common residents along the reef. Bull rays and Australian giant cuttlefish work the shallower sections, while kingfish and yellowtail scad move through in open water. Eastern blue groper are reliable throughout. May and September offer the most settled conditions.

Xanadu Reef drops from 26 to 44 metres along a wall structure that puts you firmly in deep diving territory, so gas management and buoyancy control matter here. Moderate current runs across the site, and surge can push you around on the wall, but that same water movement feeds the sponge gardens and draws in pelagics. Yellowtail scad and kingfish work the mid-water column while wobbegong sharks and Port Jackson sharks hold tight to the structure below. Keep your eyes on crevices for Eastern blue devilfish and weedy seadragons, and scan the reef face for nudibranchs and Australian giant cuttlefish. Visibility ranges from 5 to 15 metres depending on conditions.

Shark Island combines a reef, wall, and drop-off in a single site, giving intermediate divers a varied underwater landscape to work through. Depths run from 5 metres on the shallower sections down to 27 metres where the wall and drop-off reach deeper water. Visibility swings dramatically, anywhere from 3 to 40 metres depending on conditions, so you may get an intimate close-up dive or wide open water on a good day. The site regularly turns up wobbegong sharks resting on the bottom, Port Jackson sharks, Australian giant cuttlefish, and octopus among the sponge gardens. Nudibranchs reward divers who slow down and look carefully, while eastern blue groper and leatherjackets are common throughout. Current is variable, and surge near the wall warrants attention.

Boat Harbour's main draw is its cave system, which shelters a surprisingly varied mix of temperate species in depths ranging from 3 to 17 metres. Visibility runs 5 to 15 metres depending on conditions, and a moderate current keeps the water clean but demands you pick your timing carefully. Inside and around the cave, wobbegong sharks and octopus tuck into ledges, while Port Jackson sharks are a reliable find. Weedy sea dragons and giant cuttlefish patrol the shallower areas, and eagle rays pass through the wider sections. Surge and surf at the shore entry require a confident, controlled entry and exit.

Wanderers is a deep reef and drop-off site that demands respect. Depths run from 34 to 46 metres, putting this squarely in technical diving territory where bottom time is limited and decompression planning is non-negotiable. Visibility swings wildly, anywhere from 5 to 30 metres, so conditions on the day will shape your dive significantly. A moderate current runs through, which can work in your favour for drift diving but requires solid buoyancy control over the drop-off. The sponge gardens are the visual centrepiece down here, and the shark life is genuinely varied: Port Jackson sharks, wobbegongs, and nurse sharks are all realistic sightings. Eastern blue groper and Australian giant cuttlefish round out the encounters worth planning for.

The 4th-5th Reefs sit at 15 to 17 metres off the New South Wales coast and offer a solid mix of temperate reef species that reward patient, observant divers. Visibility typically runs 5 to 10 metres, giving you enough range to scan the bottom for resting angel sharks and wobbegong blending into the substrate. Keep a closer eye on rocky ledges and crevices for Port Jackson sharks and the vivid eastern blue devil. Weedy sea dragons and cuttlefish appear regularly, while schools of yellowtail, luderick, and old wife move through mid-water. There is no significant current, so you can take your time. Boat traffic is the main hazard, so a surface marker buoy is essential.

Windy Point is a shore dive combining a reef, wall, and cave system in easy shallow waters of 3 to 10 metres, making it a solid choice for beginner divers building confidence. Visibility runs 5 to 10 metres, and the current is generally mild. The site rewards slow, patient exploration. Wobbegong sharks and Port Jackson sharks rest on the bottom, while weedy sea dragons drift close to the reef. Blue groper, cuttlefish, and octopus are regular sightings. Schooling fish including sweep, yellowtail, and ladder-finned pomfret move through the water column above. Watch for rip currents and breaking waves on entry and exit.
