Best place for wreck diving in Australia
Highlights:
Explore one of the best wreck sites in the world
Dive alongside minke and humpback whales
A challenging deep dive destination
Located just off the coast of Townsville, the Yongala wreck is widely regarded as one of the best wreck dives in the world. Sinking in 1911 after a devastating cyclone, the Yongala now rests at a depth of 33 metres (108 feet), its hulking steel frame and superstructure having become a thriving artificial reef over the past century.
Gorgonian sea fans sway gently in the current while giant groupers patrol the wreck, alongside graceful eagle rays that glide effortlessly through the water.
