The old jetty pylons are encrusted with marine growth, attracting a dense concentration of macro life. Snorkelers can explore the shallow, sheltered waters (average depth 6m) where the jetty structure acts as an artificial reef. It's renowned among underwater photographers for the sheer variety of small critters hiding among the pylons — hermit crabs, baby eels, octopus and the occasional friendly sea lion. The site offers an excellent, easy-access introduction to Western Australian marine life without needing a boat.","beginner",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],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,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],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",[110,115,119,122,126,129,132,135,138],{"name":111,"description":112,"severity":113,"season_start":36,"season_end":114},"Strong currents","Ocean currents can be strong around the offshore reef, especially near cave entrances and swim-throughs.
