Kerbs, footpaths and median islands
The City sprays weeds on kerb lines, footpaths and hard stand median islands twice a year, and from the start of November for up to six weeks.
The City advertises in PerthNow Cockburn four to six weeks prior to spraying with the organic herbicide, which gives people the opportunity to put themselves on the 'do not spray' register for their own property. An advertisement will appear in the 17 March 2022 PerthNow Cockburn edition, with spraying commencing 4 April 2022.
The contractor marks the kerb directly outside the property in yellow and does not spray directly outside that property between the yellow arrows placed.

What weed killer will be used?
The City ensures the safe use of herbicides is an integral part of weed management practices for staff and residents. The City minimises chemical use where possible.
Weed management is undertaken in parks, streetscapes, natural areas and on roads, footpaths and median strips. The City does not apply herbicide to residential verges – that is the verges adjacent to private property.
While the APVMA approved glyphosate is the most commonly applied herbicide in the City, especially for road surfaces, organic herbicide products are used at some locations. Slasher Weedkiller is used for pedestrian paths. Roundup Bioactive 360 – is the herbicide applied in aquatic areas and wetlands within the City because it has been approved for use in these environments by the Australian Pesticides and Veterinary Medicines Authority.

We are limited in relation to other effective methods of weed control that can be undertaken economically in natural areas.
Glyphosate with its current constituents is considered safe, subject to compliance with the manufacturer’s safety guidelines for application, storage and cartage. Glyphosate has been approved for use by the Federal Department of Health’s Australian Pesticides and Veterinary Medicines Authority (APVMA).
The City uses low pressure spray units where possible.
Signage is installed as per the Department of Health Guidelines when chemicals are being applied. In large grassed areas, contractors display signs, use flashing beacons and use a foam residue marker to show where spraying has occurred.
The contractor spraying the kerb drives until he spots a weed and sprays directly on to the weed. They do not spray if people are in the vicinity.
All City officers are required to wear the appropriate Personal Protective Equipment and are restricted to spraying on days when conditions are favourable Favourable conditions relate to wind direction, wind speed and weather.
International and Australian considerations of glyphosate
The Australian Pesticide and Veterinary Mediciines Authority (APVMA) has indicated that glyphosate is a registered pesticide and it has been deemed safe to use as per the manufacturers instructions on the label.
The APVMA concluded that glyphosate does not pose a cancer risk to humans and that products containing glyphosate are safe to use as per the label instructions. It has not made any change to this stance since the release of the assessment outcomes on 23 March 2017.
APVMA undertook a detailed assessment of the human health risks associated with glyphosates in late 2016, following concerns raised by the International Agency for Research on Cancer (IARC).
