The historic L-shaped jetty's weathered pylons are encrusted with colourful algae and sponges, creating artificial reef habitat in shallow 2–4 m waters. A netted swimming enclosure off the side offers safe, calm conditions for beginners, while the surrounding rocky reef and seagrass beds teem with crabs, nudibranchs, garfish, and the occasional sea horse, rays, pyjama squid, or harmless Port Jackson shark. Guided snorkel tours led by marine biologists make this an educational as well as scenic underwater adventure.","beginner","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],0.005156300723018576,0.014698814320388942,0.30295803080772865,0.039204530965086117,0.15031793066686414,0.003120864363831429,0.005539919596089502,0.003039744250707542,0.008490106712638328,0.21357268684219202,0.08283914192015526,0.051000859253579306,0.022672325458079214,0.14525530188350358,0.018133861179083072,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],208.6030075617756,294.164410290647,277.83633996915455,250.8959997417711,206.4328963244539,96.06582082885262,218.6095689520406,251.2010438310257,296.31774211643346,261.5216827920577,272.7176280448664,244.30175491917868,306.6125991867919,247.06656180649207,218.16567529522547,"EOT20","1992-01-01T00:00:00Z",[109,114],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Rocky reef and pylons","Submerged rocks, reef, and jetty pylons can cause cuts or stubbed toes — wear reef shoes.","caution",null,{"name":115,"description":116,"severity":112,"season_start":113,"season_end":113},"Boat traffic near jetty","Boats may approach the jetty area; snorkellers should stay within the swimming enclosure for maximum safety.",{"directions":118,"parking":119,"facilities":120,"fees":123,"access_method":124},"Approximately 165 km west of Adelaide via the Port Wakefield Road and Copper Coast Highway.
