Swamp Wallaby

Wallabia bicolor

Also known as Black Wallaby, Black-tailed Wallaby, Fern Wallaby, Stinker

Swamp wallabies hop through dense undergrowth with a distinctive low-headed, horizontal posture and their tails held straight out behind them. Unusually among marsupials, females can conceive a new embryo while already carrying a developing fetus in an adjacent uterus, allowing continuous reproduction throughout the year. They are solitary and cryptic browsers that thrive on coarse, fibrous vegetation, even tolerating plants toxic to domestic livestock.

What to do
Never corner, touch, or attempt to handle a wild individual; give injured animals space and contact licensed wildlife rescuers.
Responsible observation
  • Road Caution: Watch roadsides carefully at dawn and dusk when individuals frequently feed near road shoulders.
  • Quiet Approach: Move slowly along trail edges, as they rely on dense cover and freeze or flee upon sudden movements.
  • Pet Control: Keep dogs leashed in bushland reserves to prevent distress or violent defensive kicks.
