Peter Garrett

Midnight Oil's frontman moved from musical and environmental campaigning into elected government. He represented Kingsford Smith in Australia's parliament from 2004 to 2013 and held cabinet responsibilities covering the environment and, later, school education. Those offices involved the machinery and accountability of government rather than a celebrity advisory title. Start with the parliamentary record to distinguish the stages of his public life. The continuity of his concerns is interesting, but the change in what he was responsible for is what makes this a second career.
