She was elected in the 2006 state election to the Tasmanian House of Assembly in the division of Bass. She has continued to hold this seat through and will contest the 2024 election.

In the 2024 Tasmanian state election, O'Byrne was the second most successful candidate across the state for the Labor Party, receiving 0.95 quotas in her own right in the first preferences alone, only outdone by then-leader, Rebecca White.^[1]

Prior to her election to state parliament she was a member of the Australian House of Representatives from 1998 to 2004, representing the Division of Bass.

O'Byrne was born in Launceston, Tasmania, a grand-niece of a former Labor senator and President of the Senate, Justin O'Byrne. She graduated from the University of Tasmania in 1992, with a Bachelor of Arts in General Studies. She was an organiser for the Liquor, Hospitality and Miscellaneous Union, and electorate officer to Senator Kerry O'Brien before entering politics.

She won the federal seat of Bass in 1998, and again in 2001, but was defeated by her Liberal opponent Michael Ferguson in the 2004 election.^[2]

Many put this down to concern about loss of forestry jobs under Labor's environment policy, which had the potential to adversely affect O'Byrne's electorate.^[3]

After more than a year out of politics, O'Byrne ran as a Labor candidate in the 2006 state election and was easily elected for the state seat of Bass, which covers the same territory as the federal seat. She topped the poll in the five-member electorate, receiving 23.3% of first preferences, helping ensure that Bass was the only seat to record a swing to Labor.

Until the defeat of the Labor government in the 2014 state election, she served in the Tasmanian cabinet as Minister for Health, Children and Sport & Recreation. She served in cabinet with her brother David O'Byrne, one of a very few pairs of siblings to have served in cabinet together anywhere in the world.^[4]

Prior to the 2010 election, O'Byrne was Minister for Environment, Parks, Heritage and the Arts, Minister for Tourism and Minister for Sport and Recreation in the Bartlett government.^[5]

A former National co convener of Emily’s List, Michelle had worked to increase the number of women in Parliament and been responsible for delivering significant legislative reform for women.

Michelle is currently the Australian Chair of the Commonwealth Women Parliamentarians who work to increase women’s participation in political processes globally.

She is a keen Parkrunner, taking part in Launceston runs when she can.

A proud product of the public education system Michelle and her partner, Priam Arumugam, live in Launceston with their two teenage daughters.^[6]
