The world's biggest blue gum is 500 years old. This 80 metre tall giant is in a Tasmanian logging coupe. Tap on the photo below.
The tree — considered to be the world's biggest known remaining blue gum — is named Lathamus Keep for its role as a stronghold for the endangered swift parrot or Lathamus discolor.

This Tasmanian blue gum, Eucalyptus globulus, was discovered by giant-tree hunters in the Huon Valley in 2021 in an area of forest slated for logging.
