Anna Reynolds will run against Andrew Wilkie in the next election.
A Labor daughter, Anna Reynolds, will carry Green hopes against incumbent Andrew Wilkie in the hotly contested seat of Denison at the next federal election.
Ms Reynolds, 45, offspring of former ALP senator Margaret Reynolds and her historian husband Henry, said involvement in issues such as climate change meant she had never favoured Labor.
"For me, the Greens are very much the party of this century," she said. Ms Reynolds is international adviser to Greens leader Christine Milne.
Though Denison is Tasmania's Green heartland, the party ran fourth on primary votes at the 2010 election. Labor, which had held the seat for 23 years, surrendered to Mr Wilkie by 1,575 votes on preferences.
Mr Wilkie, 50, told reporters yesterday he thought he could hold the seat even in the face of local suggestions that Labor may preference against him.
The ALP has named a little known mental health policy worker, Jane Austin, 44 to contest the seat, while the Liberal candidate is yet to be determined.
