While serving in the Tasmanian parliament, Brown successfully campaigned for a large increase in the protected wilderness areas. Brown led the Australian Greens from the party's foundation in 1992 until April 2012, a period in which polls grew to around 10% at state and federal levels (13.9% of the primary vote in 2010).[1] From 2002 to 2004, when minor parties held the balance of power in the Senate, Brown became a well-recognised politician. In October 2003 Brown was the subject of international media interest when he was suspended from the parliament for interjecting during an address by United States president George W. Bush.
