Senator Milne said it was a privilege to have been elected but conceded it was a "daunting task". She said protection of the environment and natural resources remained the Greens' biggest priorities.
Senator Milne said she had "plenty of experience" in minority governments and the position of holding the balance of power. She said she would embark on a "listening tour" of regional and rural Australia as the Greens had "misunderstood" the needs of farmers and those living in the bush "for some time".
Senator Brown has been a senator for 16 years. He has led the Australian Greens since the party formed in 1992, seeing the party's vote grow to double figures.
When asked about his disappointments in federal politics, Senator Brown offered that he didn't get to be Minister for Westerly Winds.
"I haven't become minister for anything or secretary for anything," he said.
He has called the Governor-General, the Prime Minister, the Opposition Leader and the leader of the Tasmanian Greens to tell them of his resignation.
"I look forward to fresh green pursuits including writing, photography, music, occasional talks, bushwalking, and getting out with (partner) Paul (Thomas) to see Miranda Gibson who has been perched for 120 days 60 metres high, in defence of a giant tree facing destruction in central Tasmania," Senator Brown said in an earlier statement.
Senator Brown - who trained as a doctor - first gained political prominence as the head of the Tasmanian Wilderness Society during the campaign to save the Franklin Dam. In 1983, he became a member of the Tasmanian Parliament.
