Meet the koala
They represent the only surviving species of an entire mammal family and have been depicted in Indigenous rock art for millennia, but koalas are under pressure like never before. In the wake of the 2019-20 bushfire catastrophe, we need to do everything we can to ensure this national icon's survival for generations to come.
“I've always loved koalas. They have a front-facing gaze that makes them almost human-like; they look directly at you, with emotions, with personality," says Meghan Halverson, Ambassador and co-founder of Koala Crusaders that helps the animals throughout South East Queensland and beyond. "They have something that's deeper spiritually where I really feel like it's like they look into your soul."
Perhaps it's this mystical quality that's ingrained the animal in the Australian psyche; koalas are a national treasure. But they're not bears. Let's just get that out of the way. Like the vast majority of other native Australian mammals they're marsupials, the last extant species of the family Phascolarctos. Okay, admittedly 'Phascolos' and 'arctos' means 'pouched bear' in Greek, but they're actually more closely related to wombats; you should think of them more as tree-climbing wombats.
But their claws are bear-like nonetheless: long and sharp to enable them to cling to the eucalyptus trees they inhabit along eastern stretches of New South Wales and deep into Queensland, and throughout the forests of southern Victoria.
The eucalyptus leaves they feed on aren't very nutritious, so they have to eat a lot of them to achieve not very much at all; they spend around 20 hours a day relaxing in the treetops. Indeed, the name koala is derived from the Dharug people's word gula, meaning 'no drink', since they so rarely appear on the ground it appears they have no need for water. In fact, their diet of leaves has a high water content, enabling them to stay up in the canopy.
However, (presumably after they've eaten several tonnes of eucalyptus leaves) they do eventually spring into life, and move from their home ranges during the mating season. Unfortunately this is when they are at most risk from dog attacks and car strikes, as they increasingly have to cross roads and backyards to find a mate. Koalas have inhabited Australia's forests for millions of years and yet the rate of urban expansion in parts of New South Wales and Queensland continues apace with little consideration for their wellbeing.
Strengthening protections for koalas is key to their survival - something the Wilderness Society is working hard to achieve with its New Nature Laws campaign. The koalas' plight has been made much worse by the recent bushfires; they've lost precious habitat that they simply cannot afford to lose, making efforts to save them more important than ever. “We have this animal that we know is in real trouble, a national icon, and yet the government is not protecting them," says Meghan.

Koalas are under threat
The 2019-20 bushfire crisis has prompted Environment Minister Sussan Ley to suggest that koalas could become listed as Endangered nationally, rather than Vulnerable, along with other species that have been severely affected.
“With fires reaching up into the canopy, very few animals have survived. And those that have been lost mark significant drops in population. So with the decline of a species already under threat, that has now just been exacerbated. Probably tenfold,” says Meghan Halverson, who has been assisting with koala rescues with her group Koala Crusaders.
On Kangaroo Island alone, over half the 50,000-strong population has been lost, a particularly bad blow because the island's koalas represent an important population free from chlamydia. The bacterial infection can lead to blindness, bladder inflammation, infertility and eventually death, and is widespread in groups of koalas around the country.
On top of being susceptible to bushfires and disease, urbanisation is a major issue. Development projects in places of rapid urban growth like south-east Queensland encroach on critical habitat, with weak environmental laws enabling developers to move into areas that have been home to koalas for millennia.
Urbanisation in areas with koalas has meant the fragmentation of their habitat, and as a result they increasingly have to cross busy roads and backyards to find new food sources and mates, leading to car strikes and dog attacks.
What you can do to help
Following a catastrophic bushfire season, koalas need our help now more than ever. We simply can't afford to have weak environmental protections any longer. The Environment Protection and Biodiversity Conservation Act (the EPBC) is Australia’s national environment law and it has failed to look after our world-famous biodiversity.
The EPBC Act is undergoing a once-in-a-decade review. It provides us with a golden opportunity to put strong protections in place to safeguard animals like koalas.
“We've lost so much habitat, and now we have [the unprecedented] fires, so there's climate change in there as well," says Koala Crusaders' Meghan Halverson. "We need to re-evaluate pre-approved development applications, anywhere where koala habitat is being cleared; you can't keep clearing trees and the connectivity between areas of habitat, it's critical for their survival. New environmental laws are needed to address that.”
In a positive step for koalas, last year the Queensland Government moved ahead with its South East Queensland Koala Conservation Strategy. If accompanied by stronger laws to protect all remaining koala habitat, it has the potential to deliver meaningful protections for South East Queensland’s koalas.
