The standout site is Olive Point headland on the island's northern side, where a healthy fringe of hard and soft corals drops off into deeper water teeming with tropical reef fish. Protected by the reef, the waters are typically calm and clear, making it easy to explore the underwater gardens. The entire island is within a Marine Park 'green zone' (conservation park), so fishing is prohibited and marine life is abundant. Camping is available behind the dunes, giving snorkellers a true island escape just a short boat ride from the Capricorn Coast.","beginner","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],0.04605587831492387,0.021920580719936727,0.30453161864049516,0.14997015031026764,1.4531557727041113,0.0096415200439523,0.004209323191012395,0.0035944843634647303,0.3146966158034493,0.15207308748181464,0.08747331392634199,0.023822576719618575,0.012340792255859741,0.47075317219740465,0.02717125952732583,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],325.15786414171225,36.193614404101595,14.110535909707139,348.8183555515227,357.2506890152998,5.511109868441135,15.748813494548374,108.93541543664493,347.0651268000009,345.9825113039547,10.2843570200306,309.2583650842123,311.73996514519376,356.4748152019967,331.15045078081226,"EOT20","1992-01-01T00:00:00Z",[109,114,117,121,125,128,131,134,137,140,143,146,149,154,157],{"name":110,"description":111,"severity":112,"season_start":36,"season_end":113},"Tidal currents","Moderate currents can run through the channels between islands, particularly around Olive Point headland.","caution",12,{"name":115,"description":116,"severity":112,"season_start":36,"season_end":113},"Boat traffic","Access is by boat only; swimmers and snorkelers should be vigilant around vessel channels.",{"name":118,"description":119,"severity":112,"season_start":120,"season_end":120},"Outgoing tide current","Swift tidal currents can develop around the headland at Olive Point, especially on an outgoing tide.
