At low tide, the sea withdraws to expose a basalt reef shaped like a giant mushroom, with a cobblestone 'stalk' and branching reef 'cap' that create a mosaic of sheltered bays, rock pools, and seagrass meadows. The ancient basalt cracks and crevices form micro-habitats teeming with marine life — from Weedy Seadragons (Victoria's state marine emblem) and Cowfish to Saddled Wrasse, Magpie Morwong, and the rare Black and White Sea Star. The shallow, calm pools make it ideal for beginners and families, while more experienced snorkellers can explore the outer reef edges.","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],0.018970764293892082,0.014618583028574711,0.21946877518460609,0.049339004868379215,0.7606865076299535,0.04942631611257367,0.006839750325907816,0.0062986371170131,0.15977024061863374,0.1520109033163613,0.06691886619029873,0.03428419873222401,0.011758736965787107,0.20793310636084633,0.022789730240178385,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],307.0048413681543,301.94838068116314,273.85627972883725,163.5882969752522,33.046575762046594,147.44087821836794,175.3400552668627,236.2159117465423,354.31208854703027,253.32687877353453,265.73764111470854,244.16449958491842,359.84682764570687,161.34287964547127,163.44323990986732,"EOT20","1992-01-01T00:00:00Z",[109,114,118,121,124,127,130,134,137,140,143,146,149,152,155,158,162,165,168],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Strong currents and undertows","Strong currents and undertows can occur when swimming and snorkelling, especially around the reef edges and at higher tides.","warning",null,{"name":115,"description":116,"severity":117,"season_start":113,"season_end":113},"Slippery rock platform","The intertidal rock platform can be very slippery, especially when wet.
