5 October 2016

Project team:  Sonia Graham, Nicholas Gill, Rebecca Cross,  Viveka Simpson, Eli Taylor and Sarah Rogers Weed hygiene supports weed control efforts and prevents the spread of weeds.  Weed management guidelines emphasize the importance of weed hygiene. However, little is known about the weed hygiene knowledge and practices among private landholders, public land managers, weed contractors and agricultural transport companies in NSW. This research explores the extent to which these key weed management stakeholders know about and implement weed hygiene practices. Download the full paper here.

Environmental contractors Total Earth Care have completed a project to remove the invasive weed Kudzu from a site in Penrith, Hawkesbury River County Council (HRCC) General Manager, Chris Dewhurst announced today. “Costing nearly $70,000 the project was funded from a number of sources including the NSW Government’s Weeds Action Program,” Mr Dewhurst said. “Kudzu is one of the world’s worst weeds because it can grow up to 30cm per day and has the ability to completely smother houses, buildings as well as all other vegetation “Kudzu has been present at Boundary Creek, Penrith, between Castlereagh Rd and the Nepean River, for more than 10 years. “Unless controlled it has the potential to spread into the main river and establish in other areas,” Mr Dewhurst said. Total Earth Care Director Andrew McGahey said controlling the plant has been difficult due to severe bank instability compounded by continuous discharges from the upstream sewage treatment plant. “Controlling the weed required a combination of herbicide applications and physical removal. “We have also revegetated the site with native plants and undertaken additional works to stabilise the banks. “After two years of intensive works the site at Boundary Creek is largely free of Kudzu, Mr McGahey said. Mr Dewhurst praised the co-operation amongst the three landowners which has been critical to the success of the project. “I would especially like to thank Virbac Animal Health who have demonstrated a long-term commitment to managing the Kudzu under challenging circumstances. “Virbac also showed real community leadership by agreeing to act on behalf of all three landowners and avoid the need for three separate projects. Mr Dewhurst said HRCC will need to monitor this site and sites downstream in the Nepean River for many years to come before we can be sure the Kudzu has been completely eradicated. “Any new plants or new growth must be immediately controlled to ensure this weed does not re-establish or spread to other areas,” Mr Dewhurst said.

Final NRC Report now released. “Weeds-Time to get Serious” – a review of weed management in NSW.

The Minister for Primary Industries, The Hon. Katrina Hodgkinson MP has requested the Natural Resources Commission (NRC) to undertake an independent evaluation of the effectiveness and efficiency of weed management arrangements in NSW with a view to inform the further development of the proposed NSW Biosecurity Act, and other relevant strategies under the NSW Biosecurity Strategy. As an initial step in the review the NRC has prepared an issues paper now available for public comment based on initial consultation and research. The purpose of this paper is to:

  • clarify priority issues
  • get stakeholder and community views about barriers and opportunities for more effective weed management
  • seek to identify any additional issues
  • identify relevant evidence to inform the review.

Hawkesbury River County Council made a submission during the review.

HRCC Media Release – Weed Authority Tackles e-Weeds

27 Feb 2014

Hawkesbury River County Council (HRCC) has moved its battle against noxious weeds on-line. The Weed Authority’s inspectors have noticed a number of people setting up business selling plants over the internet using services such as eBay. HRCC Operations Manager, Mr Chris Stanfield says “We routinely inspect traditional plant outlets such as nurseries and aquariums, but we now have to keep watch on the sale of live plants over the internet”. “These plants can cause devastating impact on our agriculture and natural environment”, Mr Stanfield said. “Noxious species such as Salvinia and Water Hyacinth can be sealed in plastic and shipped to the buyer within two days. However, Weed Authority inspectors have found good will amongst plant retailers, in both traditional and online forms. “Most are small business people only too happy to do the right thing if provided with good advice”, Mr Stanfield said. “The small number of people selling illegal weed species has stopped immediately once they have been contacted by our staff, and in most cases it appears to be a case of mistaken identity. HRCC Chairman, Clr. Bob Porter said “This is an example of how our weed authority is adapting to the modern market place.” “The County Council is continually on the lookout for new weed incursions, so if you think you have spotted one, please report it immediately.” Hawkesbury River County Council (HRCC) is the local weed authority for the Council areas of Blacktown, Hawkesbury, Penrith and The Hills Shire. HRCC has a list of all Noxious Weeds on its website at, or call 4574 9600 to report a weed. For media enquiries please contact: Mr Chris Dewhurst, General Manager T: 4574 9603 E: ebay plants

HRCC Concept for a “Biosecurity County Council”

Agnes Banks - June 2013 April 2013. Local Land Services (LLS) are the new NSW Government regional service delivery organisations that will replace Catchment Management Authorities (CMAs), Livestock Health & Pest Authorities (LHPAs) and incorporate agricultural advisory services currently provided by Agriculture NSW (DPI). The HRCC proposal utilises existing structures of local government to deliver the operational aspects of the LLS. A short one page brief can be found here.
