Also naturalised in other parts of Queensland, in the coastal districts of northern and central New South Wales, in the north-eastern parts of the Northern Territory, on Christmas Island, and in the Kimberley region in northern Western Australia.
Widely naturalised in other parts of the world, including on several Pacific islands (e.g. Fiji, Nauru, Hawaii, Palau, New Caledonia and Tonga).
Red convolvulus (Ipomoea hederifolia) is regarded as an environmental weed in northern Queensland and as an emerging or potential environmental weed in northern Western Australia and the Northern Territory. It is has escaped cultivation and is an occasional weed of bushland and riparian areas, as well as sugarcane, roadsides, gardens, disturbed sites and waste areas.
Red convolvulus (Ipomoea hederifolia) is becoming increasingly abundant in northern Queensland, and it is now regarded as a pest plant by the Cairns City Council. It is also listed as an environmental weed of the Burdekin Dry Tropics region in central Queensland. This species has been recorded in the Bowral and Kyogle districts in New South Wales, and is also present in the Narran Lake Nature Reserve in the North-Western Plains region of this state.
