I am lucky enough to have red-necked wallabies visit my place and I love the way they stand very still looking at me to make sure I am no threat. I’m not but vehicle drivers on the streets around my place often are. I’ve pulled off a dead wallaby and a friend helped me to get another badly-injured one to the vet where it was put down. Other neighbours have had similar experiences. What a terrible feeling it is to see these and other beautiful native animals dead by the side of the road. If cars weren’t bad enough, wallabies face other threats.
Australia’s larger kangaroos are generally widespread, mobile, able to use a range of open habitats and capable of fending off predators. Our wallabies are far more particular. Some depend on rocky ranges and escarpments. Others need dense woodland or particular patches of arid-country vegetation. Their smaller ranges and more specialised habitats make them especially vulnerable when Country is cleared, fragmented, overgrazed, or affected by climate change and catastrophic bushfires.
Many smaller wallabies also fall within, or close to, Australia’s notorious “critical weight range”: mammals weighing roughly 35 grams to 5.5 kilograms that are particularly devastated by foxes and feral cats.
