It is hard to guess what a Brush-tailed rock-wallaby weights. But we have the answer:
An adult Brush-tailed rock-wallaby (Petrogale penicillata) on average weights 6.94 kg (15.3 lbs).
The Brush-tailed rock-wallaby is from the family Macropodidae (genus: Petrogale). They can live for up to 14.33 years. When reaching adult age, they grow up to 19.2 cm (0′ 8″). Usually, Brush-tailed rock-wallabys have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The brush-tailed rock-wallaby or small-eared rock-wallaby (Petrogale penicillata) is a kind of wallaby, one of several rock-wallabies in the genus Petrogale. It inhabits rock piles and cliff lines along the Great Dividing Range from about 100 km north-west of Brisbane to northern Victoria, in vegetation ranging from rainforest to dry sclerophyl forests. Populations have declined seriously in the south and west of its range, but it remains locally common in northern New South Wales and southern Queensland. However due to the large bushfire event currently occurring in South-East Australia around 70% of all the wallaby’s habitat has been lost as of January 2020.
