The SS City of Sydney, a 713-ton iron paddle steamer launched in 1853, sank off the rugged NSW South Coast near Twofold Bay on the night of 5-6 November 1862 after striking a reef during a storm. The wreck now rests in 15–21 metres of water, remarkably close to shore, with the hull structure and paddle-wheel remnants still discernible amid the kelp and sandy gutters. Only accessible in calm conditions due to its exposed position, this historical wreck dive offers a rare window into Australia's colonial maritime history, with the broken iron skeleton encrusted with sponge and soft coral growth.

Moderate risk: Swell exposure
The wreck lies close to shore in an exposed position and is only diveable in calm seas. Swells can create surge and poor visibility.
Moderate risk: Ocean Swell and Surge
The wreck lies on the southern side of Haystack Rock, fully exposed to ocean swell. Surge conditions can be strong even on otherwise calm days.
Moderate risk: Strong ocean currents
Open ocean site exposed to East Australian Current flows, which can be powerful and unpredictable around the wreck structure.
Moderate risk: Boat traffic
The wreck lies in an area used by fishing and recreational vessels; snorkelers must be aware of overhead traffic.
Low risk: Limited visibility
Visibility can vary significantly depending on sea conditions and recent weather; may drop below 5 metres after storms.
Low risk: Sharp wreckage
The iron hull is broken and corroded with sharp edges and protruding metal that can cut skin or damage equipment.
Low risk: Depth range
The wreck lies between 15 and 21 metres, requiring careful depth and air management for snorkelers transitioning to freediving.
Low risk: Variable Visibility
Visibility can change rapidly after weather events or swell. Viz may drop to 3-5 m in rougher conditions.
Low risk: Cold water temperatures
Temperate NSW waters can drop to 14-18°C, requiring a wetsuit for extended snorkeling.
