Grampians ranger in charge David Roberts said a quoll was spotted in the central Grampians this month.

“We’re pretty confident that what we saw on the cameras in early February was a healthy quoll,” he said.

The endangered species had not been seen in the Grampians since 1872 – when pastoralists considered it a pest –  before it turned up in Parks Victoria’s surveillance footage late last year.

In the video, an animal deftly navigated the narrow passage of a 15-metre-deep cave.

Mr Roberts said staff had since been on alert for any further sightings.

“One of the things we’re trying to find out now is if an individual found its way into the area or if we are talking about a small colony,” he said.

Parks Victoria wants to verify the quoll’s genetic origins and 

habits.

Mr Roberts said staff also wanted to see how it interacted with other animals in the area, including predators such as foxes.
