This mid-shelf reef rises from the sapphire-blue Coral Sea, its broad shallow reef flat crowned with coral gardens and bomboras that break the surface at low tide. The reef's position near the Endeavour River mouth funnels nutrients that sustain dense coral communities, making it a vibrant underwater destination. Snorkellers drift over table corals, branching Acropora thickets, and sandy gutters where marine life converges. Access is exclusively by boat tour from Cooktown, typically a 30–40 minute ride, and the site is prized for its relative solitude compared to more crowded outer-reef pontoon locations.","intermediate",null,"published",{"name":20,"amplitude":36,"phase":52,"latitude":13,"model":68,"epoch":69},[21,22,23,24,25,26,27,28,29,30,31,32,33,34,35],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[37,38,39,40,41,42,43,44,45,46,47,48,49,50,51],0.02885689231588927,0.024323129051350752,0.30984762181113484,0.0937079698302015,0.5329650201046704,0.004737811412332346,0.011650386673577415,0.013268332963792017,0.1840076329262965,0.14787418200947644,0.09489272612621437,0.026222276591027476,0.010959423760539239,0.3274177441866257,0.023652099351281486,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],328.7373037628649,49.01931971718109,41.31008507197065,301.5355119021957,346.1887549111476,182.00824125895832,18.264976431421434,45.93634295873805,330.8119188386139,10.600799891437617,35.28551015364809,1.2984567591459115,330.8177575267797,306.0500960854347,294.7432960137712,"EOT20","1992-01-01T00:00:00Z",[71,75,81,85,88],{"name":72,"description":73,"severity":74,"season_start":17,"season_end":17},"Strong tidal currents","Tidal flows can be vigorous around the reef edge and over the flat, particularly on spring tides.
