Electoral history
Cunningham by-election
The federal division of Cunningham has been a safe Labor seat since its creation in 1949. On 16 August 2002, the sitting member, Dr Stephen Martin, unexpectedly resigned, causing a by-election. The ALP preselected a TAFE teacher, Sharon Bird, by decision of the party executive rather than the usual rank-and-file nomination procedure, and the Liberal party opted not to contest the by-election. Organ was endorsed by the South Coast Labour Council and received strong preference flows from two popular independent candidates, David Moulds and Peter Wilson. He gained 23% of the primary vote and 52% after allocation of preferences, defeating Bird and becoming the first Green elected to the House of Representatives, at the same time making Cunningham a marginal seat. During his term, he was one of three Greens federal parliamentarians.
Subsequent elections
Organ ran for a full term as member for Cunningham in the 2004 general election. He received 20.1% of the primary vote, placing third behind the Labor and Liberal candidates. This was a swing of 13.5% to the Greens compared to the 2001 federal election, but a 2.9% swing away from Organ compared to the 2002 by-election. Organ was eliminated on the ninth count, with his voters' preferences flowing overwhelmingly to Labor's Sharon Bird, allowing her to win with a 61.5% two-party-preferred vote. He was again selected as the Greens candidate for Cunningham in the 2007 federal election, but failed to regain the seat from Bird, who was re-elected on first preferences. Organ won 14.6% of the primary vote.
In his first speech, Organ credited his win to community opposition to a planned development by the Stockland Trust Group at Sandon Point. The campaign included a tent embassy by the local Kuradji nation, and a community blockade of around 300 people which was confronted by a force of around sixty police officers and police dogs. Organ said that the development was inappropriate, threatened European and Indigenous cultural heritage, threatened wetlands and a green corridor.
Economy
Organ supports free tertiary education and opposes the privatisation of public utilities like Telstra, as well as what he calls "two decades of Canberra's obsession with economic rationalism".
Iraq war
In his first speech, Organ condemned the Iraq War as unjust, in breach of United Nations resolutions, and likely to lead to higher risks of terrorism.
Organ co-authored a Greens policy on Tibet, which supported the right of Tibetans to self-determination and the Dalai Lama's Middle Way approach. He participated to the Save Tibet Asia Pacific Forum in Tokyo 1 –3 July 2008.
Marriage Equality
Organ was the only member of the House of Representatives to propose anti-discrimination amendments to the Howard Government's amendments to the Marriage Act in 2004.
