This calm, protected shoreline provides easy shore-entry access to the sparkling waters of Shoalwater Bay, where a patchwork of limestone reefs, seagrass meadows, and sandy patches teems with marine life. From here, snorkelers can swim towards nearby Penguin Island and the chain of islands that define this marine park, enjoying clear, shallow waters ideal for spotting fish, stingrays, and the occasional playful sea lion. The Point's gentle conditions and convenient parking make it a favourite launch pad for families and snorkel tour operators alike, offering a quintessential Perth-region marine adventure.","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],0.004138255641140625,0.009100934676354215,0.16712810092975103,0.014615285462913732,0.05287839209855107,0.004532580355073513,0.0043761610059752445,0.004658670296748399,0.01395122398217303,0.12144491362904936,0.05124507917871472,0.023338793184845205,0.012680799720642446,0.0411397135029236,0.00262858239039233,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],51.440990170955466,224.07046495493967,181.38993203477355,34.1184239872897,57.3134776224858,139.95715412737724,28.57387552934816,232.08145044492517,108.19639413611452,175.70225030214988,170.9042552168189,172.95596287067735,321.16277221407677,61.83143503496228,245.3368145548592,"EOT20","1992-01-01T00:00:00Z",[109,114],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Current around reef channels","Strong tidal currents can develop between the islands and around reef channels, especially during outgoing tides.","caution",null,{"name":115,"description":116,"severity":112,"season_start":113,"season_end":113},"Boat traffic","The area is used by tour boats and private vessels launching nearby; keep watch for boats near the entry point.",{"directions":118,"parking":119,"facilities":120,"fees":124,"access_method":125},"Located off Safety Bay Road in Shoalwater, approximately 50 km south of Perth CBD.
