This is the most common macropod in Australia's wet tropics. It is especially abundant on the coast flood plains of Arnhem Land. In the wet season floods drive wallabies off the coastal plains and back to the base of the escarpment where grasses are sparse. Despite the fluctuations of the food supplies, the wallabies breed all year. The young leave the pouch at seven or eight months and are weaned about ten months.
Females mature at one year.
Males weigh up to 27kg and are about 1.2 metres high when sitting on their haunches. Females are smaller. Both sexes are a light sandy fawn, paler on the chest and belly, with a distinct pale hip stripe and a pale cheek stripe beneath a darker eye line. Males develop longer more heavily muscled areas and broader shoulders. Agile wallabies are commonly preyed upon by dingoes.
