As Margaret says, Oz has a national clean up day despite the fact that the place is relatively clean from rubbish. Also what helps is the fact that we have on the spot fines of aus$150.00 or more (depending on the amount and state)dished out to anyone caught. This includes indicriminately throwing cigarette butts and lolly papers onto the ground or where ever. Maybe that would help
providing you got your local council off their butts and started imposing fines for littering
