Known for its intricate swim-throughs, caverns, and ledges, the reef offers incredible underwater topography with depths from 10–22 metres. Schools of western blue groper, dhufish, samson fish, and buffalo bream patrol the structure, while western rock lobsters, wobbegong sharks, octopus, cuttlefish, and Port Jackson sharks hide beneath ledges and in crevices. The warming Leeuwin Current nurtures sponge gardens, gorgonian fans, and soft coral cover, making this one of the Perth region's most popular and productive snorkel and dive sites.","intermediate","published",{"name":58,"amplitude":74,"phase":90,"latitude":22,"model":106,"epoch":107},[59,60,61,62,63,64,65,66,67,68,69,70,71,72,73],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[75,76,77,78,79,80,81,82,83,84,85,86,87,88,89],0.004246646050641868,0.00929715593939091,0.16671990024248595,0.013763551056940972,0.05442926686434654,0.004831037571235754,0.005031046440380575,0.004593391224684983,0.013459586396300377,0.12210902263225695,0.05066823186019397,0.023037956390366602,0.013620958504661312,0.04165109266427433,0.002988107938348202,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],38.07168459976013,226.5547116816707,181.76307460570933,39.03973987574349,58.69595906491372,131.53454162642942,33.33911075183571,222.96465763182368,105.85905092868404,176.01364000372735,171.0963195429075,173.02286853875765,319.8592487484466,64.23281584403975,227.84649155086737,"EOT20","1992-01-01T00:00:00Z",[109,115,119,125,128,133,136],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":114},"Exposure to wind and swell","The reef is exposed to wind, swell, and surge from the Southern Ocean.
