Mandurah residents march to parliament over years of industrial odour
Mandurah residents are staging a parliament protest on November 10 over persistent, severe odours from nearby C-Wise (composting) and CM Farms (piggery).
Years of complaint over industrial odours are bringing Mandurah residents to Western Australia's State Parliament on November 10 at noon. C-Wise and CM Farms, confirmed by government in 2024 as the odour sources, have made millions in infrastructure upgrades, but residents say the smell remains frequent and severe enough to prevent opening windows and using backyards in summer.
Activist Wendy Bouquet, who runs the Facebook group Lakelands And Surrounds Stink, says the stench forces families inside even with air conditioning running and that some residents feel nauseated. C-Wise has invested over $6 million in facility upgrades and is undergoing pond work meant to reduce long-term odours, though some of this work has temporarily worsened the smell.
Both businesses had their operating licences amended at the end of 2025 with stricter odour monitoring, planning and infrastructure requirements. Advocacy groups remain unconvinced the core problems have been solved and want government assurances that the odours pose no health risk.
