Widely naturalised, particularly in the wetter parts of mainland Australia. It is most prominent in the coastal and sub-coastal regions of New South Wales and in south-eastern Queensland. Relatively common in Victoria, the ACT, south-eastern South Australia and south-western Western Australia. It also has a scattered distribution in other parts of these states.
Widely naturalised overseas, including in North America (i.e. southern Canada, the USA and Mexico), Central America, South America, south-eastern Asia (i.e. the Philippines, Thailand, Indonesia and Papua New Guinea), New Zealand and on numerous Pacific islands (e.g. Fiji, French Polynesia, Guam, Hawaii, New Caledonia, Palau and Tonga).
