Christine Anne Milne AO (née Morris; born 14 May 1953)[2] is an Australian politician who served as a Senator for Tasmania.

Milne was born in Latrobe, Tasmania, the second daughter of Wesley Vale dairy farmers Tom and June Morris.

She first came to public attention for her role in opposing the building of the Wesley Vale pulp mill near Bass Strait in North Western Tasmania on the basis of its environmental impact.

She was part of the Labor–Green Accord, a political agreement between the Australian Labor Party (ALP) and the Tasmanian Greens to form government after the 1989 general election had resulted in a hung parliament.

[7] Preferences to Family First from the Australian Labor Party almost prevented her from being elected; however, she managed to reach a quota mostly as a result of the high level of below-the-line voting in Tasmania.

Milne was part of Bob Brown's frontbench covering the portfolios of Arts, Climate change, Competition Policy & Small Business, Finance & Administration, Food Security, Regional Australia, Resources & Energy, and Trade.
