Meet the site
Cosy Corner is a small sheltered cove on the Leeuwin coast near Augusta, and one of the few easy shore dives this far south. Marinelife.org.au describes reef platforms close to shore in about 7 m, with overhangs full of smaller fish such as scalyfin, blue devils, morwong, foxfish and harlequin fish, and warns about the steep hill from the car park when fully loaded with gear.
The overhangs are the attraction: western blue devils and harlequin fish are two of the most colourful temperate reef fish in Australia, and finding them in a few metres of water close to shore is a treat. Weed and kelp cover the reef tops, and the cove's shelter makes it pleasant on calm days.
It suits Open Water divers and snorkellers who are prepared for the climb back to the car. The offshore islands and reefs nearby (listed separately as Cosy Corner Offshore Reefs) are better reached by boat from Hamelin Bay.
There are no facilities at the site; Augusta has shops, fuel and accommodation.
The coast around Cape Leeuwin is where the Indian and Southern oceans meet, and it is one of the most exposed shorelines in Australia. The sheltered coves and bays near Augusta are the exceptions, which is why local divers value them. There is no dive shop in Augusta, so bring filled cylinders from Busselton or Perth, and remember that the nearest recompression chamber is at Fiona Stanley Hospital in Perth, about four hours' drive away. Ngari Capes Marine Park zoning includes sanctuary zones at Cape Leeuwin and East Flinders Bay, so check the maps before fishing or collecting.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Cosy Corner is recorded as Shore/Rock Platform in Margaret River & Augusta. The listed access is shore. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
