An enormous natural tower made of coral has been discovered in the northern Great Barrier Reef that is taller than the Auckland Sky Tower or the Empire State Building.
Closer to Queensland's Cape York than New York the natural reef tower was uncovered during a 12 month research mission by the Schmidt Ocean Institute.
The discovery made last Tuesday is said to be the most significant find on the reef in 120 years.
Data returned from their unmanned submarine – named SuBastian – showed images of a spire-like reef that rises over half a kilometre to a peak just 40 metres below the ocean surface.
