Your First Dives After Open Water in South Australia: Where to Go, Who to Ring, What to Hire
The 5 easiest, most rewarding dive sites in South Australia for a newly certified diver, plus what a first boat day is like, what to hire, when to go and the next course.
South Australia may be the best place in the world to be a new diver, because its signature sites are jetties: shallow, sheltered, shore-entered by stairs, and home to leafy seadragons, giant cuttlefish and sponge gardens that experienced divers travel across the country for. The gulfs are cool (13–22 °C) and calm on the right days, and a dodge tide every fortnight gives a day with almost no water movement at all.
The 5 dives to do first
| Site | Access | Depth | Why first |
|---|---|---|---|
| Rapid Bay Jetty | Shore | 3–10 m | The leafy seadragon site: stairs off the new jetty into seagrass, the old jetty's pylons beside it, and the animal you came to South Australia to see in 6 m of water. |
| Port Noarlunga Reef & Jetty | Shore | 3–12 m | Adelaide's most popular shore dive: stairs from the jetty into a sheltered reef lagoon with a marked underwater trail, thirty minutes from the city. |
| Edithburgh Jetty | Shore | 3–9 m | Arguably the best jetty dive in the country, with 150-year-old piles covered in sponges and every small creature of the southern reefs; flat water and a ladder entry. |
| Ewens Ponds, Mount Gambier | Shore | 3–10 m | A guided drift through three spring-fed ponds in near-perfect visibility; freshwater, 15 °C, and open to Open Water divers with a booking. Nothing else looks like it. |
| Stony Point cuttlefish, Whyalla | Shore | 2–8 m | May to August only: hundreds of giant cuttlefish displaying and mating in 3 m of water off the rocks. A snorkel or a dive, and one of the great wildlife events. |
What your first boat day is like
Boat diving in SA is mostly the ex-HMAS Hobart out of Wirrina, the Adelaide metro wrecks and the Eyre Peninsula's sea lion swims. The Hobart's superstructure at 5–18 m suits Open Water divers with a guide, and the charter will pair you with one. Sea lion swims at Baird Bay and Hopkins Island need no certification at all and are worth the drive.
What to hire and what to buy
Full kit with a 7 mm suit $80–100 a day; Adelaide shops also hire drysuits for the sinkholes. Buy a 7 mm semi-dry and hood; the gulfs are cold from June to October.
When to go
February to May for the gulfs; the cuttlefish are a winter event; the sinkholes are the same all year.
Habits that make the first twenty dives safe
Dive with someone who knows the site for your first visit anywhere; every state has clubs and shop-run social dives for exactly this. Check the swell and wind against the site page's conditions section the night before, and have a sheltered alternative. Stay within your certification depth (18 m) and above your comfort depth, which is usually shallower. Do a proper buddy check every time, carry a surface marker on any boat dive, and log everything: operators ask how many dives you have and when the last one was, and honest numbers get you better sites.
The next step
Advanced Open Water for the Hobart's decks, then the CDAA Deep Cavern course if the sinkholes get under your skin.
