Townsville, Ayr & the SS Yongala · Queensland
Scuba Diving at SS Yongala
A 100-metre passenger steamer lost in 1911, now carrying possibly the densest marine life in Australia.
The SS Yongala is one of Queensland's most important individual dive attractions and is regularly described as among the best wreck dives in the world.
The wreck is around 100 metres long and lies at depths reaching roughly 30 metres. Queensland tourism material treats the site as an advanced diving attraction.
Marine life around the wreck can be exceptionally dense because the wreck provides substantial structure away from major surrounding reef systems. It sits on an otherwise featureless seabed, which concentrates every structure-dependent species in the area onto it.
The ship was lost in a cyclone in 1911 with all 122 people aboard. It is a protected historic site and a gravesite, and penetration is not permitted.
Recommended: Advanced Open Water Diver. Parts of the site reach 30 m, which needs Advanced Open Water, ideally with the Deep specialty. What can I dive with my cert?

These are guidance categories, not guarantees. Conditions on the day, and an operator’s own requirements, override any classification here.
- Queensland groupers, often very large
- rays including eagle rays and bull rays
- turtles
- sea snakes
- dense schooling fish including trevally and barracuda
- pelagic species
- bull sharks occasionally
Possessing an entry-level certification does not automatically make every diver equally prepared. Operators may impose additional experience or supervision requirements, and those requirements exist for good reasons.
- recent depth experience
- comfort managing current
- ascent control without a reference
- gas consumption at 25–30 metres
- boat diving experience
- comfort with no nearby reef rising toward the surface
The Yongala is protected under historic shipwreck legislation. Penetration is not permitted, nothing may be removed, and divers are asked to avoid contact with the structure.
None of this limits the dive meaningfully. The marine life is on the outside.
The wreck is an isolated structure on a sand plain roughly 20 kilometres offshore. Every species that needs structure — for shelter, for hunting, for cleaning — concentrates here.
The result is a density of large animals that reef diving rarely produces, in a comparatively small area.
Access
- Boat access from Ayr (shorter transit) or Townsville.
- Exposed offshore location — trips are weather-dependent.
- Descent is typically down a mooring line against current.
Hazards
- current, which is frequently significant
- depth with limited no-decompression time
- no shallow reef to ascend onto
- blue-water ascents without a fixed reference if the line is missed
- marine life encounters requiring calm behaviour
