The inner and outer reefs, separated by a sheltered channel called 'The Gap', support vibrant kelp gardens, intertidal rockpools, sponge beds and soft corals. Snorkellers can explore shallow gutters and ledges teeming with wrasse, zebra fish, globe fish, abalone and sea urchins, while Australian Fur Seals haul out on the outer island. The site offers easy shore-entry snorkelling from the southern end of Marengo Beach on calm days, with deeper, more exposed areas for advanced exploration.","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],0.010885873073581147,0.012727418842047143,0.2027092200004056,0.0418036233451588,0.4856872033397414,0.03672382059058758,0.005519615596314503,0.006391837954696599,0.09596112599718604,0.14396466595022472,0.06244959630039474,0.029025122609636092,0.020591364349564198,0.1871690959814815,0.016066996219755308,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],280.4475382006379,289.6626579793081,262.74646226635065,141.6362994734847,24.024007223593262,125.4701924523149,164.95941118384616,231.4156568249466,339.1925848735346,243.33860916389153,257.2010462759959,231.1152755665329,12.591760610157422,137.39189002141939,146.44988441749638,"EOT20","1992-01-01T00:00:00Z",[110,114,117,121,124,127,130,133,136,139,142,147,151,154],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Strong currents and undertows","Sudden changes in weather can create strong currents and undertows when snorkelling, especially near the reef edge.","warning",{"name":115,"description":116,"severity":113,"season_start":56,"season_end":56},"Large unexpected waves","Swell can produce large unexpected waves on the rock platforms and reef, posing a risk of being swept off.",{"name":118,"description":119,"severity":120,"season_start":56,"season_end":56},"Slippery rock platforms","Intertidal reef rocks can be very slippery — wear shoes with good grip when walking at Hayley Point or the inner reef.","caution",{"name":122,"description":123,"severity":113,"season_start":56,"season_end":56},"Aggressive Australian Fur Seals","Seals on Henty Island can be aggressive if approached.
