They dig a burrow system with multiple exits in the ground or under limestone rocks. Burrows are dug with their front paws equipped with long and sharp claws. The length of the passages can reach up to 20 meters. Recent fires in eastern and southeastern Australia have shown that burrows are often much longer than initially thought. Some have more than 20 entrances, and many wombats' burrows were used by other species, including rock wallaby and swamp wallaby, to shelter from the fire. Whether this was done with the consent of the burrow's "owner" is not known.
