Despite its name, this is not a true cave but a dramatic 14 m-deep crevice in the reef wall, capped by a massive lodged boulder that creates a swim-through cavern. The site is accessed from a rock platform adjacent to the Skillion car park, with a short surface swim before descending along a kelp-covered slope. Inside the cave, walls blaze with jewel anemones and gorgonians, while schools of yellowtail scad, bullseyes, and ladder-finned pomfret swirl overhead. On the sandy floor, look for wobbegongs, Port Jackson sharks, and bull rays resting in the shadows. Outside the cave, a sheer wall drops to 15–18 m, rich with colourful fixed growth and macro life. This site is best attempted on flat, calm days — rough conditions make entry and exit over the slippery rock platform dangerous.","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],0.018218761427807158,0.010902664004321301,0.16094432055069532,0.031072246608811985,0.4982823639375277,0.007211225619638797,0.0028864951314464533,0.0027469950810933455,0.10982563793758199,0.09276734245657438,0.04741762937971225,0.015413610603990057,0.015791000027708165,0.1237878577300927,0.008055244902808087,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],280.23155433667563,8.082080116897089,327.3942141766802,315.29234340159445,307.40091328773053,259.15821180661345,235.3951041525401,88.18906400239575,295.3904247382072,297.7859539730283,322.1215536392267,271.71696978959386,318.53205159496423,314.42652875069564,262.91305723936534,"EOT20","1992-01-01T00:00:00Z",[110,116,119,123,126,129,132,135,138,142,145,149,152,156,159],{"name":111,"description":112,"severity":113,"season_start":114,"season_end":115},"Swell and surf surge","This site can ONLY be attempted on calm days.
