Central Coast Divers is a family-run SSI dive centre based at Killarney Vale on the NSW Central Coast, just over an hour north of Sydney, established in 1987. The business is led by a father-and-son instructional team who bring decades of local diving and teaching experience, and it is best known for guiding divers to the ex-HMAS Adelaide, Australia's largest scuttled warship and one of the most diver-accessible wrecks on the Australian coastline, now covered in colourful sponges and soft corals. The centre runs the full range of SSI training from Try Scuba and Open Water through Advanced, bundled course packages, Extended Range technical diving and Mares Horizon semi-closed rebreather try-dives, alongside boat dives to local reefs and wrecks and organised local and overseas dive travel. It also stocks a large range of scuba, freediving, spearfishing and snorkelling gear, offers equipment servicing, hire and oxygen refills, and runs the Trident Scuba Club for social diving on the Central Coast.
