The site features a dramatic pincer-shaped reef formation that juts into Bass Strait, creating a protected northern bay with a sandy and rocky floor. Snorkellers can explore towering Giant Kelp forests, swim-throughs, and shallow rocky bommies fringed with Bull Kelp. The site sits within the Barwon Bluff Marine Sanctuary, renowned for its incredible intertidal diversity including colourful sponges, sea squirts, and abundant reef fish.","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],0.014363225805707668,0.014061530311070677,0.21493894154805687,0.04633988165595081,0.6938710367553813,0.049448729223001496,0.006372342433336643,0.005963525655015214,0.1424753020081663,0.15095726522854191,0.0656115914379758,0.032938667145294094,0.01579019156767787,0.2064022990393771,0.020563528150482673,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],301.8701855856734,297.22967114912194,269.6579605792015,155.36691651275282,30.193797044089198,140.08230358184466,169.16882591978106,228.6434266796457,350.5551357737894,249.97849091286207,262.52990610589825,239.103555277471,4.802309689570763,153.48697809745943,157.85464202104924,"EOT20","1992-01-01T00:00:00Z",[110,115,118,124,129,134,137,140,143],{"name":111,"description":112,"severity":113,"season_start":36,"season_end":114},"Cliff Instability \u002F Rockfall","Recent rockfall events at the Barwon Bluff — keep clear of cliff bases and stay away from fallen rock debris.
