Its standout feature is the extensive fringing reefs that wrap around the south-eastern and northern sides of the island, offering exceptional snorkelling and diving in calm, protected waters. At low tide, the reefs are exposed, allowing for incredible reef walking among hard and soft corals, tropical fish, and sea turtles. With only one campsite (max 6 people), this is a true off-grid island escape — untouched, remote, and utterly pristine, with the Southern Great Barrier Reef's vibrant marine life right at your feet.","intermediate","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],0.04612934918048467,0.022019278167772414,0.3050194133538998,0.1505826523095552,1.4604513161915227,0.00859060510722147,0.004234766832191878,0.00357731546746329,0.3159842567887136,0.15229155148436707,0.08768147311561372,0.023731951271224995,0.012080395790755337,0.4731240911238416,0.027379296498603167,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],325.4082963075989,36.10640216021538,14.217668169841524,349.0138596836601,357.4962177054015,6.46617963184359,15.744813376095157,106.34752875965633,347.2857446013168,346.1136425094816,10.320296391467604,309.5137103117079,310.2639246091949,356.65036181413984,331.5487143327777,"EOT20","1992-01-01T00:00:00Z",[109,114,118,121,124,127,130,133,136,139,142,145,148,151],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Sharp coral and reef walking hazards","At low tide, the fringing reefs become exposed with sharp coral edges.
