Like other shipwrecks in shallow tropical seas, it has been colonised by coral, sponges, fans and other sessile (fixed in one place) marine life.

As an oasis and shelter rising from the sandy sea floor, it has also become home for a myriad of fish, as well as turtles and other marine animals.

Then in early February 2011, almost 100 years after SS Yongala sank, she encountered another cyclone.
A category 5 monster, Severe Tropical Cyclone Yasi, tore into the coast driving huge seas. Would the SS Yongala survive another cyclone?

The first divers to revisit SS Yongala after the cyclone discovered something extraordinary.
Whilst the wreck was still there, most of the encrusting marine life had been scoured away by the terrible storm.

Once again the SS Yongala looked like a recent shipwreck, stripped and laid bare..

testament to the incredible power of Cyclone Yasi.

But here and there, in protected areas, some encrusting marine life remains.
Almost immediately the ocean’s inhabitants again had begun taking over the wreck.
Before long this unique opportunity to see “SS Yongala revealed” came to an end, with only photos to remember the amazing impact of SS Yongala’s second cyclone.
