The site features a dramatic underwater archway over a narrow sandy gutter, creating a natural amphitheatre where Grey Nurse Sharks gather in impressive numbers. Thanks to the East Australian Current pushing warm tropical water south, the reef flourishes with an extraordinary blend of tropical and sub-tropical marine life — think clownfish (Nemo), blue tangs (Dory), and vibrant hard and soft corals draped over the rocky substructure. Depths range from 5–20 metres, making it a must-visit for competent snorkellers.","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],0.027081769754098126,0.009297528801829135,0.18494575571082753,0.03336276149301931,0.5339266572395216,0.0035549498245619282,0.0038044069617792493,0.004332179907136025,0.11248396915671652,0.09498617004889383,0.05709507008010678,0.020727185168253497,0.012555317061360692,0.14021896601068295,0.01126041923907555,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],293.80676584544096,5.264344068278009,342.415507352856,294.8391252784765,302.49761032396987,280.98059142905333,202.55376175344333,24.03505494427603,294.98870465759717,315.31356905305296,341.28609661169696,278.11435898284424,317.64170169047287,314.155994560082,339.87698074213483,"EOT20","1992-01-01T00:00:00Z",[110,114,118,121],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Strong Ocean Currents","The East Australian Current can create strong, unpredictable currents around the island and through the arch, especially on an outgoing tide.","warning",{"name":115,"description":116,"severity":117,"season_start":56,"season_end":56},"Boat Traffic","Access is by boat only and the site is near a transit lane; snorkellers must stay aware of vessel movements.","caution",{"name":119,"description":120,"severity":117,"season_start":56,"season_end":56},"Variable Visibility","Visibility can change rapidly due to swell, currents, and plankton blooms, ranging from 5–20+ metres.",{"name":122,"description":123,"severity":113,"season_start":56,"season_end":56},"Deep Water Entry","The site drops to 20 metres with no shallow shore entry; snorkellers should be confident in deep, open water.",{"directions":125,"parking":126,"facilities":127,"fees":131,"access_method":132},"Manta Arch is located at South Solitary Island, approximately 12 km north-east of Coffs Harbour.
