Managing weeds

  • Some weeds can threaten agriculture, human health, and the environment including bushland areas, roadsides and waterways.
  • To reduce weeds, the whole community needs to help. Many weeds can travel across property boundaries and in some cases, landowners may need to take action on their land to stop the spread of weeds. 
  • Find out how we are helping to tackle weed issues through our weed control grants program, Weed Management Strategy 2019-29, Weedbusters Week annual event and support of local weed control projects including the Hills Ragwort Action Project. 
  • Our weed directory will help you identify common weeds in Cardinia Shire. We also have  tips on removing weeds and suggestions for plants you can replace them with.
  • You are responsible for managing weeds on your property (under Local Law 17 and the Catchment and Land Protection Act) and we are responsible for land and water areas under our management.
  • We have the authority to ask landowners to control weeds on their property and to issue fines as needed under Local Law 17.
