In an interview in 2001 for a history of the WA peace movement she said: "The
Quakers influenced me I suppose from the
Vietnam Moratorium days because I was a teacher then, in 1967-69, when the marches were getting going in Perth, and I can remember being a bit nervous because in those days if you were seen in a protest you might have lost your job on Monday when you went to work." At her first election campaign in 1984, media interest was focused on the NDP Senate candidate for New South Wales,
Midnight Oil's singer
Peter Garrett. However, under the Australian Senate's voting system of proportional representation, Western Australia was the only state to return an NDP senator. Soon after her election, Jo Vallentine resigned from the NDP, held her Senate seat as an independent and was re-elected in the 1987 election. She also marched on the American
Clark Air Base in the
Philippines in 1989. In 1990, as the inaugural
Greens WA Senate candidate, she was re-elected again but resigned on health grounds before completing her term. The casual vacancy was filled by
Christabel Chamarette. Her efforts took a toll. After resigning from the Senate, Vallentine took time to recuperate from ill health. By 1994 she was helping found
Alternatives to Violence Project in Western Australia, focused on sharing
nonviolent skills with people in prisons. She also travelled with the 1997
peace pilgrimage, was involved in the
Jabiluka campaign, successfully campaigned to keep the estuary at
Guilderton free from urban development on the south side of Moore River, and continues to oppose the 2003
Iraq War, the use of
depleted uranium in Iraq (and its possible use by the US at
Lancelin) and expansion of nuclear power and weapons. She later participated in protests against Woodside's
North West Shelf Project, and pled guilty to a charge of trespassing. She attempted to ask the court for a community service order, but received a fine. == Legacy ==
