The 417-metre jetty sits over a sandy seabed fringed with green seagrass and offers a maximum depth of just 6–7 metres, making it exceptionally accessible for beginners and families. Each jetty pile hosts a vibrant micro-ecosystem of soft corals, sponges, and colourful encrusting life. Beneath the jetty's shaded structure, inquisitive cowfish greet snorkellers, while the debris and fallen piles at the jetty end are a macro-photographer's dream. This is one of South Australia's best jetty dives — calm, protected, and teeming with life.","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],0.0074419324137684735,0.014513001078227311,0.2885067196784633,0.05032550592433884,0.1616182536854474,0.0008594966928942572,0.004236377988048441,0.004555316791785769,0.009122633904575602,0.2030854897699873,0.08062778946734017,0.04865570685789389,0.019806693250351934,0.16755048141358597,0.017512068571694694,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],198.80445554766754,293.01258039636457,274.0902107776842,219.50698007462518,181.1868408327677,43.9700425037644,208.6561903302985,255.85228878578607,260.7712247653986,257.3115204264629,269.5674222551389,241.16567828726699,305.1567001266943,221.83898158076147,208.3357290708825,"EOT20","1992-01-01T00:00:00Z",[109,114,119,122,125],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Fishing gear entanglement","The jetty is popular with fishermen; snorkellers should stay directly under the jetty to avoid monofilament lines and hooks.","caution",null,{"name":115,"description":116,"severity":112,"season_start":117,"season_end":118},"Cold water temperatures","Winter water temperatures can drop to 13°C; even summer temps rarely exceed 24°C.
