Surrey Hills (postcode 3127) is part of City of Boroondara, which sets bin collection days by street rather than by suburb — so the exact day varies address to address within Surrey Hills itself.
Yellow-lidded bin — collected every week, more often than most Victorian councils.
Green-lidded bin for food and garden organics, also collected weekly.
Red-lidded bin — collected fortnightly on an A/B week roster that depends on which zone your street is in.
