A sugar glider is being dragged outside by two cops. It has just dumped a pile of woodchips inside the Victorian Treasury Office and yelled, ‘Stop woodchipping the water catchment, Brumby!’As you might have guessed, this is no ordinary marsupial. Rather, it’s an activist in costume, an activist with a sense of humour – an activist with the guts to cross the thin blue line, to challenge the police, fight for a cause and make the government look silly.
