The sloping seabed is littered with massive granite-like coral boulders and coral bommies that rise from 20 metres to just below the surface. These formations create a labyrinth of swim-throughs, ledges, and gullies teeming with pelagic life. Strong tidal flow brings nutrient-rich water, attracting large schools of fish, mackerel, and the occasional hammerhead shark. Accessible only by boat from the Whitsundays, this site offers some of the most dramatic underwater topography in the region.","intermediate",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],0.03360802817104002,0.022305232038798025,0.35229800634273434,0.0989064931767836,0.9997816160650151,0.01631885049315954,0.0019581985509781012,0.007112496003746626,0.2519868153905829,0.17605215987753908,0.10708746436097331,0.03248259589168377,0.0052883293030253275,0.34592852210297004,0.020690990253708293,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],358.65642085760663,50.70534856221499,38.45334129998494,352.1049323048968,24.421366747044548,94.50471029125089,88.28251942120141,184.06082985730478,5.764252123768016,10.827199474818713,33.91328108718647,342.8397080364554,320.715162977178,355.1962017855585,314.7483820058508,"EOT20","1992-01-01T00:00:00Z",[110,114,120],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Strong Tidal Currents","Tidal currents can be strong around the boulder formations, especially during spring tides.
