Weeds in Australia
Invasive weeds are among the most serious threats to Australia's natural environment and primary production industries. They displace native species, contribute significantly to land degradation, and reduce farm and forest productivity. Australia spends considerable time and money each year in combating weed problems and protecting ecosystems and primary production on private and public land.
About weeds
Invasive weeds are among the most serious threats to Australia's natural environment and primary production industries. Weeds have major economic, environmental and social impacts in Australia, causing damage to natural landscapes, agricultural lands, waterways and coastal areas.

Weed management
The first step in weed prevention, and the most cost-effective means of managing weeds, is to prevent potential weeds entering Australia. When a weed has taken hold, early detection and eradication are critical steps to reduce their impact.
