Researchers observed ten other species, six of which used them on multiple occasions.
The intruders ranged from rock wallabies and bettongs to skinks and birds. Little penguins were recorded using burrows 27 times, while the black-footed rock wallaby was observed using wombat burrows more often than wombats, visiting nearly 2,000 times in eight weeks.
One of the reasons for this is that wombats often move between a number of homes, therefore leaving their space for squatters.
In fact, a 2012 study tracked one wombat to 14 different burrows.
While wombats are often regarded as quite sedentary, another study found the average home range size of common wombats is 172 hectares.
