Helicia australasica

Helicia australasica, also named Austral oak or creek silky oak, is a species of rainforest trees, and constitutes part of the flowering plant family Proteaceae.

Its everyday name in the local northeast Queensland Dyirbal language was miyabur, though a more general word gurruŋun "oak tree" (also applied to Darlingia ferruginea and Cardwellia sublimis) was used in the taboo [Dyalŋuy] vocabulary.

They grow naturally through New Guinea and in Australia in central and north eastern Queensland, Cape York Peninsula and the Northern Territory, from about 0 to 1,100 m (0 to 3,609 ft) altitude.

They are threatened by habitat loss.

They have been recorded growing up to about 20 m (66 ft) tall.
