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.

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.

Voodoo is a reef and wall site that drops away to 28 metres, combining a shallow reef top with a proper wall and drop-off that rewards divers who push deeper. Visibility runs 10 to 25 metres, with the clearest conditions typically in June and August. Moderate current is the norm, but it can build quickly, so solid buoyancy and drift experience matter here. Wobbegong and Port Jackson sharks rest along the wall, bull rays cruise the sandy transitions, and Australian giant cuttlefish are a reliable find. Sponge gardens dominate the deeper structure, with nudibranchs scattered throughout. Kingfish and Eastern blue groper work the mid-water column.

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.

Voodoo Wide is a multi-feature site combining wall, reef, cavern, and drop-off terrain that rewards divers who can work with moderate currents and surge. Depths run from 20 to 30 metres with visibility reaching 15 to 25 metres on good days. The site's structure creates sheltered pockets where Australian Giant Cuttlefish, Weedy Seadragons, and various nudibranchs congregate, while Port Jackson Sharks, Wobbegong Sharks, and Nurse Sharks favour the deeper sections and cavern recesses. Yellowtail Scad and Eastern Blue Groper round out the fish life. Rip currents, strong surge, and depth make this a boat-access site suited to experienced divers only.

Whale Of A Time is a shore entry reef dive in New South Wales sitting at 18 to 22 metres, with visibility swinging between 5 and 25 metres depending on conditions. Moderate to strong current and surf entry demand solid buoyancy control and situational awareness, and decompression management is a real consideration at depth. The reef rewards methodical divers who slow down and look closely. Weedy seadragons and pygmy pipehorses are among the standout finds, alongside anglerfish, nudibranch, and octopus. Giant cuttlefish, moray eels, blue groper, eagle rays, and Port Jackson sharks round out a genuinely varied temperate assemblage.

Osbourne Shoals is a reef dive with enough variety to keep intermediate divers engaged across multiple visits. Depths run from 9 metres on the shallower sections to 24 metres in the deeper waters, with visibility ranging from 5 to 20 metres depending on conditions. Mild current keeps things manageable. The resident marine life leans distinctly temperate: blue groper and red morwong are reliably present, Port Jackson sharks rest on the bottom during winter months, and cuttlefish are well worth slowing down for. Schooling species including mado, stripey, bullseye, old wife, and striped seapike add movement to the water column, while leatherjackets pick around the reef structure.

The Hilda is a wreck dive sitting in 21 to 27 metres off New South Wales, rewarding advanced divers who can manage moderate to strong current with solid bottom time on an intact structure. Visibility ranges from 10 to 30 metres, so on a clear day you can take in the full scale of the wreck from mid-water before descending. The hull and superstructure are colonised by sponges and ascidians, while nudibranchs work their way across encrusted surfaces. Wobbegong sharks and Port Jackson sharks rest in the shadows, and Eastern Blue Groper, Red Morwong, Sea Pike, and Yellowtail Scad move through the water column. Nurse sharks occasionally shelter beneath the wreck.
