Old Man's Hat is a boat dive off New South Wales that rewards beginners with a genuine cave feature and an impressive mix of temperate marine life. Depths run from 5 to 25 metres, so newer divers can stay shallow while still exploring comfortably. Visibility reaches 10 to 25 metres in clear conditions, making it easy to spot creatures like weedy sea dragons, eastern blue devil fish, and flying gurnards. The site also shelters Port Jackson sharks, wobbegong sharks, and crested horn sharks resting on the bottom, along with cuttlefish, nudibranchs, blue groper, and pygmy leatherjackets. Current is moderate, so stay aware of your position, particularly near the cave.

This shallow New South Wales reef suits beginners well, with calm water and visibility that can reach 25 metres on a good day, though it can drop to around 2 metres after rough weather. Keep an eye out for weedy sea dragons drifting among the reef growth, and wobbegong sharks resting on the bottom (give them space and they are not a concern). Blue groupers are often curious and approachable. Cuttlefish and octopus are regulars here too. Fur seals, dolphins, and manta rays pass through on occasion. Watch for surge near the reef, boat traffic above, and always approach marine life calmly and without touching.

Store Beach is one of the few places in New South Wales where you can reliably encounter fairy penguins underwater. The site sits in easy shallow waters between 5 and 10 metres, making it a comfortable choice for beginner divers. Visibility typically runs 5 to 10 metres, and the current is mild, so you won't feel pushed around. Much of the bottom is covered in seagrass beds, which is exactly the kind of habitat fairy penguins hunt in. Watch them dart through the water hunting small fish. Entry is by boat, and boat traffic in the area is an active hazard, so stay aware of your surroundings.

Flag Staff is a shore-entry site in Tasmania that suits beginners thanks to its shallow, calm waters. You can expect to find various reef species as you explore, though visibility here is variable, so conditions can change from one visit to the next. Current is also variable, so it pays to check local conditions before you get in the water. Because visibility can be limited, this site rewards a slow, patient approach rather than covering distance. Take your time near the bottom and you will have a better chance of spotting what lives among the reef.

Quarantine Station is a gentle, sheltered dive that suits beginners well. Depths run from 3 to 16 metres, so you can stay shallow and comfortable while you build confidence. Visibility typically ranges from 4 to 10 metres, giving you enough to spot the site's highlights: seahorses and pipefish tucked among the bottom, cuttlefish drifting in open water, stingrays resting on the sand, and old wives moving in loose groups. Lionfish are present and beautiful to look at, but keep a respectful distance as their spines are venomous. Currents are mild, which makes navigation straightforward for newer divers.

South Head drops you into deep diving territory where the continental shelf meets the Pacific, creating a dramatic underwater landscape that sorts the weekend divers from the committed. Descending through 22 to 37 metres, you'll navigate a site that demands respect and rewards experience. Visibility ranges from 5 to 25 metres depending on conditions, so planning around settled weather and favourable tides makes the difference between a memorable dive and a challenging one. The depth brings nitrogen narcosis into play, whilst boat traffic overhead and potential surge add layers to your dive planning. What draws advanced divers back is the quality of encounters rather than quantity. Weedy seadragons drift through kelp forests, cuttlefish materialise from rocky outcrops, and blue devil fish stake their territory amongst sponge gardens. Yellowtail kingfish patrol the blue, whilst moray eels and groupers hold station in deeper crevices. Fiddler rays rest on sandy patches between rock formations, and patient divers spot seahorses anchored to holdfasts. Crayfish occupy the darker recesses. The mild current keeps things manageable for experienced divers, though you'll want solid buoyancy control and proper decompression planning. This isn't a site for exploring limits but rather for applying well-honed skills in a demanding environment.

Harrys Hill Beach is a shore entry site suited to beginner snorkellers and divers exploring shallow, calm waters over seagrass beds and reef. The mix of habitats draws a good variety of animals, including bream, flathead, mado, sweep, drummer, and blue groper moving through the reef areas, while octopus, sea hares, and nudibranchs reward slower, more careful searching in the seagrass. Green sea turtles visit the site too. Visibility is variable, so conditions can shift, and despite the sheltered feel, moderate currents and rip currents are present. Always check conditions before entering, and stay aware of boat traffic in the area.

Centurion is a boat dive off New South Wales that suits beginners well, sitting at a comfortable 16 to 18 metres with mild current. Visibility swings widely, anywhere from 1 to 30 metres, so conditions vary from murky to crystal clear depending on the day. The site rewards slow, patient divers who look carefully rather than cover distance. Keep an eye out for red indian fish and pineapple fish tucked into crevices, wobbegong sharks resting flat on the bottom, and giant cuttlefish patrolling the area. Octopus, eels, and blue groupers round out the regular cast. Be aware of boat traffic overhead, surge near structures, and the possibility of reduced visibility.
