Fish Rock Cave offers one of the most thrilling drift dives on Australia's east coast, combining a genuine cave swim-through with encounters that include grey nurse sharks and occasional hammerhead sharks. The cave itself runs 125 metres through Fish Rock, starting at 24 metres and emerging at around 14 metres on the northern side. Most of your dive happens between 10 and 14 metres, where moderate currents sweep you through the main passage. The 30-metre visibility lets you spot marine life well before you reach it. Grey nurse sharks often hover in the cave entrance and around the exits, whilst black cod lurk in darker recesses. Outside the cave, you'll find bull rays and eagle rays cruising the surrounding reef, with kingfish and crayfish common along the rock face. Sea turtles pass through regularly, and leopard sharks appear during winter months. The overhead environment demands solid buoyancy control and torch skills. Surge can push you around near the entrances, particularly on rougher days. The moderate current helps with the swim-through but requires you to time your entry properly. Most operators run the dive as a drift, picking you up after you've completed the cave traverse and explored the outer walls.

The Fish Market is a shore dive off New South Wales that runs from a manageable 12 metres down into deeper water reaching 30 metres, giving intermediate divers room to explore at their own pace. Visibility swings considerably, anywhere from 3 to 30 metres, so conditions vary significantly between visits. Variable currents add another layer to factor in before you enter. The site rewards patience, with various reef species making use of the structure across the depth range. Summer months from December through March tend to offer the most reliable conditions. Check surf reports before heading out, as breaking waves and surge can make the entry and exit demanding.

Foggy Shark Cave sits in deep diving territory off the New South Wales coast, where a dramatic pinnacle rises from 35 metres to within 6 metres of the surface. The site combines overhead environments with wall diving and reef structures, attracting an exceptional variety of shark species. Grey nurse sharks congregate here year-round, often joined by hammerheads, leopard sharks, and wobbegong sharks resting in crevices along the wall. The cavern systems require careful navigation through moderate currents, with visibility ranging from challenging to 15 metres depending on conditions and depth. Bull rays cruise the sand channels between reef sections, while giant cuttlefish, black cod, and blue groper inhabit the rocky outcrops. Moray eels peer from holes in the wall, and sea turtles pass through on hunting runs. The moderate current keeps the site clean but demands strong buoyancy control, particularly when entering and exiting the overhead sections. Boat access handles the depth and current requirements, though shore entry is technically possible for those who prefer it. The site's year-round diving window means shark encounters remain consistent across all seasons, though current strength and visibility vary with weather patterns and swell direction.

Black Rock is a reef dive off New South Wales that rewards beginners with a genuine mix of reef life at manageable depths. The shallower sections sit around 8 metres, making it easy to get comfortable before venturing into deeper waters reaching 22 metres. Visibility swings considerably, from 3 metres on murky days up to 30 metres when conditions align. Current runs moderate, so stay aware of surge near the reef. Look carefully along the reef structure for wobbegong sharks resting flat, octopus tucked into crevices, moray eels, scorpion fish, and the delicate detail of nudibranchs and egg cowries. Grey nurse sharks and turtles also pass through. Give lionfish and sharp coral a wide berth.

Green Island offers a straightforward boat dive combining a wall, reef, and the option to drift with a mild current. Depths run from 10 metres on the reef to 21 metres in the deeper sections, and visibility in these crystal clear waters typically reaches 30 metres, so you can see clearly across the reef without any difficulty. The wall is a good feature for beginners to follow, keeping your orientation simple while you take in the various reef species along the way. Currents are generally mild, but they can strengthen, so stay close to your dive guide and keep an eye out for boat traffic on the surface.

The Training Wall is a shore dive in New South Wales suited to new divers, offering shallow, calm waters and visibility that can reach 25 metres on a good day. The site combines a wall structure with an artificial reef, giving you varied terrain to explore without venturing deep. Currents can be variable and occasionally strong, so check conditions before you get in and stay close to the wall if flow picks up. Keep an eye out for turtles, rays, and grey nurse sharks moving through the area. Boat traffic is an ongoing hazard, so always surface with a safety sausage and stay aware of your surroundings.

Trial Bay Gaol (Front Beach) offers an ideal introduction to diving, with easy shallow waters between 5 to 10 metres and excellent visibility ranging from 10 to 20 metres. You can enter from the shore or arrive by boat, making it flexible for your first dives. The reef here supports a diverse cast of marine life that keeps every dive interesting. Watch for moray eels tucked into crevices, curious cuttlefish changing colours, and fiddler rays gliding over the sand. Nudibranchs decorate the reef walls in surprising colours, while pineapple fish hide in darker spots. You might spot shovel nose rays cruising the bottom, and if you're lucky, green turtles pass through the area. Between April and September, humpback whales migrate along the coast, sometimes visible from the surface. The site experiences mild current and some surge, which is manageable for beginners but good to be aware of. Boat traffic does pass through, so stay alert and use a surface marker buoy. After your dive, you'll find parking, toilets, showers, and a cafe nearby. The combination of accessible conditions, varied marine life, and proper facilities makes this an excellent spot to build your confidence underwater.

Korogoro Creek is a calm, shallow estuary snorkel and dive spot sitting within Hat Head National Park. With depths of just 0 to 2 metres, this is a gentle introduction to underwater exploration, though visibility can vary considerably depending on conditions. The seagrass beds are worth slowing down for: flatheads rest motionless on the sandy bottom, octopus tuck themselves into crevices, and wobbegong sharks lie camouflaged and still. Mullet move through in loose schools, and hermit crabs go about their business in the shallows. Check conditions before entering, as rip currents and breaking waves can develop near the creek mouth.
