Dive-site story
The SS Tuggerah, a coastal coal carrier lost during heavy seas south of Port Hacking in 1919, lies inverted on a sand seabed off the Royal National Park coast. Its stern retains an intact propeller and rudder assembly, whereas the collapsed midsection exposes boilers, steam machinery, and hull plating. Given the bottom profile and open-ocean exposure, this site demands technical decompression and mixed gas.
