This platform-accessible reef system features impressive coral bommies, expansive plate corals, and vibrant marine gardens in crystal-clear oceanic waters. The reef's position on the outer continental shelf delivers excellent water clarity, making it ideal for spotting colourful reef fish, rays, and turtles. Day tours from Airlie Beach bring snorkellers to a floating pontoon or mooring, where they can spend hours exploring the coral gardens that surround this less-visited gem of the southern Great Barrier Reef.","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],0.027484273036861677,0.02128512453026419,0.3212183778550258,0.07723903440310285,0.6272410196757127,0.012445844307729978,0.003641450819200105,0.0023658929077567947,0.1852791326268051,0.16309107912737703,0.09515006373463336,0.028775039442543972,0.006133522009812735,0.2745057180809082,0.018263038804483166,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],326.7061687250718,46.30865207651983,33.211471866083784,319.4455238902375,357.67448660998303,57.74353570573508,23.39253304612021,122.83450450771888,341.14052324476404,6.827592478878696,29.106510023980334,341.53720365171176,326.66122656996197,320.7838071257821,285.9001805052609,"EOT20","1992-01-01T00:00:00Z",[110,115,119,124],{"name":111,"description":112,"severity":113,"season_start":36,"season_end":114},"Outgoing tide current","Strong currents can sweep across the outer reef, particularly on falling tides.
