Chadstone (postcode 3148) is part of City of Monash, which sets bin collection days by street rather than by suburb — so the exact day varies address to address within Chadstone itself.
Red-lidded bin — collected fortnightly, not weekly. Monash reduced general waste collection to encourage more food and garden waste recycling.
Yellow-lidded bin, collected every second week.
Green-lidded bin — collected every week, the opposite pattern from landfill waste.
