Emus remain common in most of the more lightly settled parts of mainland Australia. Overall population varies from decade to decade according to rainfall; as low as 200,000 and as high as a million, but a typical figure is about half a million individuals. Although emus are no longer found in the densely settled southern and south-western agricultural areas, the provision of permanent stock water in arid regions has allowed the mainland species to extend its range.
