The site features both shallow and deep wreck trails — including a 12-metre wooden boat, a 19-metre yacht, and a 21-metre barge — connected by pole markers through the riverbed. Visibility typically ranges from 3–4 metres but can open up beneath the freshwater layer in the saline tidal wedge. This protected river location makes it a popular all-weather alternative to ocean snorkelling, though divers must contend with boat traffic and mooring lines. The grassy reserve provides a pleasant spot to gear up before entering the calm waters of Mosman Bay.","intermediate",null,"published",{"name":20,"amplitude":36,"phase":52,"latitude":13,"model":68,"epoch":69},[21,22,23,24,25,26,27,28,29,30,31,32,33,34,35],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[37,38,39,40,41,42,43,44,45,46,47,48,49,50,51],0.004069325823909827,0.009580000548645941,0.16611524296546198,0.014440773295855464,0.054810839874245496,0.004814749443883301,0.004811842523596494,0.004765109170341946,0.013737111875289554,0.12162132956348988,0.05054214454923644,0.02301955323559473,0.015695631430451714,0.04187806720123667,0.002783104438818689,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],42.10913576643702,226.59353320467483,181.78257235747367,35.716919813675986,58.15611909694036,137.3296854619773,31.286949502097734,226.83045619214965,106.35504050734063,176.18030674893157,170.98156153344047,173.28370864095223,311.95285072805956,62.99541932275986,232.04190429418964,"EOT20","1992-01-01T00:00:00Z",[71,75,79,82],{"name":72,"description":73,"severity":74,"season_start":17,"season_end":17},"Boat traffic and mooring lines","The Coombe is located in a busy mooring area.
