The swamp wallaby (Wallabia bicolor) is a small macropod marsupial of eastern Australia. This wallaby is also commonly known as the black wallaby, with other names including black-tailed wallaby, fern wallaby, black pademelon, stinker (in Queensland), and black stinker (in New South Wales) on account of its characteristic swampy odour.
The swamp wallaby is the only living member of the genus Wallabia. Historic names for the swamp wallaby include Aroe kangaroo. The swamp wallaby is known as banggarai in the Dharawal language. The swamp wallaby is found from the northernmost areas of Cape York Peninsula in Queensland, down the entire east coast and around to western Victoria and south-eastern South Australia, where it has greatly expanded its distribution over the past four decades. Advances in rabbit control appear to have resulted in extension of the swamp wallaby's distribution, which has expanded since the time of European settlement.
It inhabits thick undergrowth in forests and woodlands, or shelters during the day in thick grass or ferns, emerging at night to feed. They have been found to inhabit diverse habitats such as open farmland... Wikipedia →

Possible
About 20% of wildlife watchers report a Swamp Wallaby sighting in Blue Mountains National Park on a given day, based on 75 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 21 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Swamp Wallaby in Blue Mountains National Park on a given day, against about 10% in April, the lowest month. That is one of Blue Mountains National Park's driest months, with about 40 mm of rain against 150 mm in March.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Swamp Wallaby sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 11
Of the 11 parks where we can rate Swamp Wallaby sightings, Blue Mountains National Park ranks 9th at about 20%. The best odds are in Wilsons Promontory National Park (Australia, about 80%), Grampians National Park (Australia, about 70%) and Booderee National Park (Australia, about 60%). All parks ranked.
Same family: Macropodidae
The closest relatives of the Swamp Wallaby that you can see in Blue Mountains National Park (family Macropodidae, Kangaroos, Wallabies and Allies) are Eastern Grey Kangaroo (about 30%), Red-necked Wallaby (about 20%) and Wallaroo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Swamp Wallaby is recorded against all the mammals logged in Blue Mountains National Park (75 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
