"Fred O'Mallee" as it is nicknamed can be found near Swan Reach Conservation Park on private property. According to the nominees, Fred Mallee is reportedly the largest mallee tree in Australia, at 19m in height with a canopy spread of some 29m.

It is estimated to be some 2,000 years old. You can find out more about this special tree here.

20 Metre Trees

Last Year's Winner

This character Dingley Dell gum (Eucalyptus leucoxylon subspecies megalocarpa) can be found in Port MacDonnell and was voted by you as the winner of the 2021 competition!

This sub species, has a larger nut than its smaller fruited 'cousins', found roughly 100km to the north. It is found in several forms of habit in the SE of South Australia, from prostrate along cliff tops, to tall and/or twisted. The one pictured, is colloquially known as the Port MacDonnell gum, found near the town of the same name, at the southern most point of SA. I am nominating this tree, as there aren't many mature examples of this tree left, due to the development of farmland in the area. The species is also South Australia's southernmost gum. She's twisted and beautiful, especially in the mottled light of a setting sun!
