Naturalised in the coastal districts of southern and central Queensland, in the coastal districts of northern New South Wales and on Lord Howe Island. Sparingly naturalised in south-eastern South Australia and near Melbourne in southern Victoria. Possibly also naturalised in south-western Western Australia and in the coastal districts of central and southern New South Wales. The distribution of this species is probably underestimated by herbarium records, as it is difficult to collect and preserve.
A weed of bushland, waterways, gullies, forest margins, pastures, forestry plantations, urban areas, abandoned homes, disturbed sites, waste areas, roadsides and railways in the humid and sub-humid temperate and sub-tropical regions of Australia.
