Overview

Christine Anne Milne (born 14 May 1953) is an Australian politician best known for her role as a Senator representing Tasmania and for serving as leader of the Australian Greens. She became party leader on 13 April 2012, succeeding Bob Brown, and led the party through national debate on climate, energy and social policy before stepping down in 2015. Milne is widely recognised for her long-term commitment to environmental campaigns and progressive politics.

Background and early activism

Born and raised in Tasmania, Milne was active in local environmental movements and community organisations long before entering federal politics. Her early career combined grassroots campaigning on forest protection, anti-nuclear issues and sustainable development with involvement in Tasmanian state-level politics, helping to shape a profile as a principled advocate for conservation and regional communities.

Parliamentary career

Milne served as a Senator for Tasmania and was prominent in debates on climate policy, renewable energy, land management and social welfare. In federal parliament she earned a reputation for tenacity and detailed policy work, often emphasising the links between environmental sustainability and economic fairness. She succeeded Bob Brown as leader and was the parliamentary leader of the Greens during a period of heightened national focus on emissions reduction and energy transition.

Policy priorities and positions

  • Climate and energy: strong support for ambitious emissions reductions and an urgent transition to renewable energy.
  • Conservation: protection of native forests, coasts and biodiversity.
  • Social justice: attention to inequality, housing and regional development.
  • Indigenous and community rights: advocating respectful consultation and recognition.

Legacy and later work

Milne is widely regarded as a key figure in bringing environmental issues into mainstream Australian political discussion. After leaving party leadership and later the Senate, she continued to be involved in public comment, advocacy and advisory roles related to climate and sustainability.
