Eucalypt of the year celebrates the beauty and importance of Australia’s iconic eucalypts. This annual event highlights the incredible diversity of these trees and their significance to our landscapes, biodiversity and heritage.

Eucalypt of the Year 2026 – Our Eucalypt Home 

Unique. Irreplaceable. Treasured.

Think it’s only humans that yearn to find their dream home? Ask a Koala, Swift Parrot or Murray Cod what they need to survive and you’ll find that a gum tree fits the bill. Eucalypts support our Australian wildlife in a surprising number of irreplaceable, ingenious and often invisible ways. With little fanfare, these quiet achievers keep our unique animals, plants and fungi fed, watered, sheltered and safe. And with an abundance of threats to our eucalypts, it’s up to us to protect these iconic trees and the irreplaceable role they play in Australia. After all, home is where the gum is!

Darwin Stringybark (Eucalyptus tetrodonta), NT

The Darwin Stringybark is one of the dominant trees in Australia’s tropical savanna, The straight trunks of this medium tree are favoured by termites, which hollow out the timber and return nutrients to the soil. The tree lives on, and threatened species like the Black-footed Tree Rat and Palm Cockatoo make their homes in the hollow. The straight tubes of termite-affected trees are perfect for making didgeridoos. An infusion of the bark can be used as a treatment for dysentery , while a mashed paste from the leaves can be used for headache and fever. The Darwin Stringybark is also a key nectar source for flying foxes, possums, tree rats, honeyeaters and parrots at a time of year when little other food is available.

Threatened by gamba grass burns, land clearing and unsustainable commercial harvest for cheap didgeridoos.

Mountain Ash/Swamp Gum (Eucalyptus regnans), Vic, Tas

The world’s tallest flowering plant and beloved by Australian forest wildlife. Mountain Ash Forests are home to the majority of the world’s population of tiny Fairy Possums (Leadbeater’s Possum), which make their communal homes in its hollows. Massive Powerful Owls, Greater Gliders, Mountain Brushtails and Yellow-bellied Gliders find hollows to suit them too. Joining their friends in these epic apartment blocks, colonies of Spencer’s Skinks have been spotted basking and hunting 50 metres above the ground!

Scribbly Gum (Eucalyptus haemastoma), ACT, NSW

Long have ecologists and artists alike been fascinated by the intricate patterns wending their way back and forth across the Scribbly Gum’s smooth, powdery bark. In the 1930s CSIRO scientists discovered the artist behind these works to be the larvae of the tiny Osmograptis moth. But it wasn’t until 2012 that they worked out how the moth larvae created their written messages, by tunnelling just below the bark and feeding on the next year’s growing wood.

River Red Gum (Eucalyptus camaldulensis) Vic, NSW, Qld, SA, NT, WA, ACT

Who doesn’t this tree provide for?! From bringing water up from deep water tables and channeling it across desert landscapes, to providing leaves, nectar, pollen, sap and wood for hungry wildlife, and playing host to hollow-nesting species from tiny pardalotes, microbats and budgerigars to massive Powerful Owls, Lace Monitors and black cockatoos! In rivers, fallen River Red Gums and living roots create sheltered zones for Murray Cod and Golden Perch to mate, spawn and ambush prey.

Manna Gum/ White Gum (Eucalyptus viminalis), Vic, Tas, NSW, SA

A wide-range of species use the Manna Gum’s hollows for nesting, including the endangered Forty-spotted Pardalote, which feeds almost exclusively within White Gum canopy. A sugary sap called ‘manna’ is produced by the bark in response to insect attack, and this is enjoyed by everyone from tiny pardalotes to humans! This manna can form up to 80% of the Forty-spotted Pardalote’s nestlings’ diet! Endemic to Tasmania, this tiny bird also eats invertebrates and sugary lerps on the leaves.

Forest Red Gum/ Queensland Blue Gum (Eucalyptus tereticornis), Qld, NSW, Vic

This is one of the most important food trees in Queensland and a primary food source for Koalas on the east coast of Australia. It produces masses of small, creamy flowers, which are attended by pollinators of all shapes and sizes, from tiny flies to honeyeaters and parrots by day, and moths, flying foxes and marsupials by night.

Mugga Ironbark (Eucalyptus sideroxylon), Vic, NSW, ACT, QLD

The Mugga Ironbark forms an important component of the winter-flowering Box-Ironbark Forests of eastern Australia. These trees and forests are favoured by Critically-endangered Regent Honeyeaters and Critically Endangered Swift Parrots, the latter of which are a migratory species and depend on Box-Ironbark Forests while wintering on the mainland. Interestingly, the brush tongues of Swift Parrots and lorikeet species have co-evolved with ironbark (and the closely-related Yellow Gum) flowers to get early access to nectar and spread pollen over wide distances during their nomadic foraging flights.

Kingscote Mallee (Eucalyptus rugosa), SA

This unassuming mallee eucalypt is emblematic of the many abundantly flowering southern and southeastern mallee eucalypts, whose predominantly white flowers reflect a generalist pollination strategy, attracting a wide variety of vertebrate and invertebrate predators. The nectar and pollen of the Kingscote Mallee have been shown to be favoured by the tiny Western Pygmy Possum over other eucalypts, plants and insects in Innes NP SA, perhaps due to differing sugar ratios between the nectar of this and other species.

Marri (Corymbia calophylla), WA

The white-flowering Marri is a keystone species in southwest Western Australia, where it provides pollen and nectar for native bees and other wildlife at a time when few other species are flowering. The fruit (gumnuts) and seeds of this species are staples in the diet of the Critically Endangered Baudin’s Cockatoo, the Endangered Carnaby’s Cockatoo, the Vulnerable Red-tailed Black Cockatoo and the Red-capped Parrot. Older Marri Gum’s bear wide and deep hollows for these large species to nest in.

Small-fruited Red-mahogany (Eucalyptus resinifera), QLD, NSW

The Small-fruited Red-mahogany is the favoured food of the Endangered Northern Yellow-bellied Glider, a large gliding possum. The gliders chew holes in the tree’s bark and feed on the free-flowing sap that flows out to try and block the wound. This makes the sap available to other bird and mammal species, including the Little Red Flying-fox and Spectacled Flying-fox, Broad-toed Feathertailed Glider, Common Brushtail Possum, Striped Possum and Krefft’s Glider.
