It goes without saying that the world’s largest reef system touts many natural wonders. But what might surprise you are the few man-made wonders the reef is home to as well — and, one, in particular, is well worth exploring: the wreck of SS Yongala.
After she sank in a cyclone in 1911, killing all 122 people onboard (as well as a racehorse named Moonshine and a Lincolnshire bull), the SS Yongala became enshrined with coral. Today, the wrecked ship is home to rays, sea snakes, octopuses, turtles, bull sharks, tiger sharks and hundreds of species of fish.
Per law, you are forbidden from entering the ship, so be sure to enjoy the sights from the outside — the penalty for entering is a fine and arrest.
