The site features a steep coral wall adorned with dense hard and soft corals, including large gorgonian sea fans, with excellent visibility averaging 25 m. The reef teems with pelagic life — grey reef sharks, dogtooth tuna, and trevally patrol the drop-off while turtles and manta rays glide through the blue. The pristine, uncrowded reef is part of the Cocos Keeling Islands Marine Park, one of the healthiest reef systems in Australia with minimal bleaching impact.","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],0.00826076325066531,0.00904887210623066,0.14336638260417275,0.030622844591985287,0.30531522332189864,0.0008740767418695095,0.01415360532379826,0.011120584129918593,0.0721012036918002,0.09215761131210151,0.045370939372370786,0.016935312766890368,0.006331318576814775,0.11278000557850175,0.010874441721726138,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],277.1915846456511,190.5235368806509,153.92418081881283,348.8255113283175,312.80137483714776,130.18073608833484,359.9500517924407,347.98934137186063,299.71936514378564,146.09361850575687,149.7840506376352,130.64552949034206,312.78414350539026,344.1203067739333,353.6926874934807,"EOT20","1992-01-01T00:00:00Z",[71,75,78],{"name":72,"description":73,"severity":74,"season_start":17,"season_end":17},"Tidal currents","The site can experience moderate to strong tidal currents, especially on the incoming tide which brings upwelling and active pelagic feeding.","warning",{"name":76,"description":77,"severity":74,"season_start":17,"season_end":17},"Deep drop-off","The site is located on the outer reef with a deep wall dropping to 30-40 m, requiring careful depth management.",{"name":79,"description":80,"severity":81,"season_start":17,"season_end":17},"Wind-dependent access","The site is only accessible on calm days when winds are low, typically during the summer months (November-March).","caution",{"directions":83,"parking":84,"facilities":85,"fees":88,"access_method":89},"Big Brother is a dive site in the Cocos Keeling Islands Marine Park, accessed by boat from West Island or Direction Island.
