What is the maximal age a Brush-tailed rock-wallaby reaches?
An adult Brush-tailed rock-wallaby (Petrogale penicillata) usually gets as old as 14.33 years.
Brush-tailed rock-wallabys are around 30 days in the womb of their mother. When born, they weight 56 grams (0.12 lbs) and measure 1 cm (0′ 1″). As a member of the Macropodidae family (genus: Petrogale), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 15.2 cm (0′ 6″).

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.
