The offshore reefs and coastal waters surrounding the islands feature fringing coral reefs, rocky headlands, and white-sand bays with excellent visibility. This is a wild, undeveloped marine environment where you can explore untouched reef systems teeming with tropical fish, turtles, and rays. Snorkeling here is typically accessed via guided fishing or snorkeling tours from Darwin, as the islands are Aboriginal-owned land requiring a permit. The surrounding waters are famed for their bluewater, reef, and estuary ecosystems, offering a truly off-the-beaten-path adventure into one of Australia's most remote snorkeling destinations.","intermediate","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],0.030894284193651304,0.036216004005850934,0.59570148172185,0.23619383476746714,1.781389344787536,0.05603660864888884,0.015853699106739092,0.008172097276337333,0.33203296875459803,0.3304322625898226,0.14928454328417415,0.0773986278917326,0.03552953744574751,0.8577199259863106,0.044119563949201746,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],199.12531484238764,237.20585931102073,200.26387843858151,294.3770318598433,249.81308046112366,72.25717971553044,8.16215413971517,321.2471797217089,225.55556616522358,188.79264228523368,201.1838808518653,180.44604104202608,10.087109934375805,297.856486135382,295.5078891475907,"EOT20","1992-01-01T00:00:00Z",[109,114,119,124,127,130,133,137,140],{"name":110,"description":111,"severity":112,"season_start":36,"season_end":113},"Saltwater Crocodile Presence","Crocodile sightings are possible in nearshore and estuarine waters around the Tiwi Islands, particularly during the wet season.
