Unlike a true enclosed cavern, this limestone formation creates a dramatic tunnel beneath the seabed — like a natural stadium passage — where shafts of sunlight pierce through openings above. Divers and snorkellers glide through the cavern while schooling fish flit past the walls. The site sits within the Jurien Bay Marine Park, renowned for its resident Australian sea lion colony and vibrant reef ecosystems, making Marty's Cave a unique geological and marine highlight of the region.","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],0.0010993250214843273,0.00893134580769481,0.17161879758227755,0.017722011743893994,0.05551672252212398,0.0049411692395705375,0.006802237875647502,0.004013548202907803,0.01354321012905716,0.12247229419292487,0.04634027896376775,0.02691613462386949,0.019369634219004304,0.04172859183616169,0.002657088629366009,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],33.271594690438036,223.54177187892844,180.25460584496534,43.6191551257018,60.2464010572059,161.44411737550763,45.99185489938913,187.62418553482541,92.04351509528976,175.21783809669887,170.72208864628885,172.61485572024253,4.292793337911974,70.98928775046255,341.26283785131665,"EOT20","1992-01-01T00:00:00Z",[110,114,120,123],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Enclosed swim-through","The cave is a tunnel-like swim-through with limited overhead clearance; snorkellers must be comfortable in enclosed spaces and should not enter if claustrophobic.","warning",{"name":115,"description":116,"severity":117,"season_start":118,"season_end":119},"Surge and swell inside cave","Swell can push snorkellers into rock walls inside the cave.
