Noxious Weeds

Weeds pose a significant threat to the wellbeing of the Australian economy, the community and environmental sustainability

In NSW, Local Government is bound under the Noxious Weeds Act 1993 to ensure, as far as practicable, that occupiers of private land carry out their obligations to control noxious weeds imposed under the Act.

Weeds in our area

Inverell Shire is geographically diverse. Rising some 1400 metres above sea level (ABS) in the Maybole/Ben Lomond region and falling to less than 250 metres ABS around Yetman in the north.

As a result, the Shire lends itself to a wide range of cool and warm temperate weeds. Our more temperate areas provide ideal conditions for noxious weeds like Blackberry, St John's Wort, Chilean Needle Grass, Serrated Tussock, Sweet Briar, Nodding Thistle, and Paterson's Curse; while the warmer regions grow Green Cestrum, African Boxthorn, Mother of Millions, Silverleaf Nightshade, and a variety of prickly pears including Tiger Pear, Harrisia Cactus, Velvety Tree Pear and Common Prickly Pear. Other non noxious weeds of interest include Blue Heliotrope, Mimosa Bush, Mulga/Rock Fern and Coolatai Grass. (Follow the links for Council's factsheets on these weeds and their control).

Council's role

Inverell Shire Council Council is committed to preventing the introduction of new weed species and reducing the negative impact of noxious and other environmental weeds, by conducting a strategic private property inspection program, roadside surveillance and treatment, and building weed awareness through field days and media on local weed issues (see our Weed of the Week page).

One of the main roles of Council in weed control is to respond to and prevent the introduction of new high risk weeds (which if suspected have to be reported to Council or the NSW Department of Primary Industries within 24 hours).

Recent incursions in the Inverell Shire include Water Hyacinth, Water Lettuce and Tropical Soda Apple. New incursion weeds are defined as either not yet established in NSW or in parts of NSW, and significantly threaten the social, economic and environmental prosperity of the State.
