Even though wallabies are native to Australia, you'd be hard-pressed to find them casually hopping around in the city.

It's perhaps why police got quite the surprise when a swamp wallaby was found bouncing along the Sydney Harbour Bridge, one of the city's busiest roads, early Tuesday morning.

Traffic controllers and police monitored the wallaby's trip down the highway, where it made an exit at the Cahill Expressway. 

Police finally took the startled animal into custody near the Conservatorium of Music, where it was taken to Taronga Zoo for treatment. It's thought that the wallaby came from a golf course in Cammeray, located in the city's north.

"The Swamp Wallaby remains in a stable condition at Taronga Wildlife Hospital's Intensive Care Unit," Taronga’s Senior Veterinarian Larry Vogelnest said in a statement via email. 

"At this stage, it doesn't appear to have any serious injuries, however, it will be carefully assessed over the next 24–48 hours. As with all wildlife brought into our care, our hope is that the wallaby will be able to be released back into the wild. An assessment will be made on the best location for this release in due course."

Only in Australia, once again.
