The Nobbies sits off Phillip Island and delivers one of Victoria's more engaging temperate dives. Depths run from 10 to 20 metres with visibility reaching 8 to 15 metres on a good day. The real draw here is the Australian fur seals, which are genuinely curious and will often approach divers on their own terms. Weedy seadragons, rays, and Port Jackson sharks make regular appearances, and reef fish are present throughout. Plan for moderate current that can strengthen, plus surge and cold water, so a drysuit or thick wetsuit is worth packing. Entry is by boat only.
