Rusa is the Malay word for deer and they are medium sized, rough-coated deer which are biologically allied to the sambar. However, the two species are quite different in size, appearance and behaviour. There are two subspecies established in the wild in Australia and the Javan rusa (Cervus timorensis russa) is the larger. Stags stand up to 110cm at the shoulder and may weigh around 136kg while hinds are considerably smaller at 95cm and 60kg.
