Australian Greens leader Christine Milne is playing down the resignations of six of her senior staff members and has dismissed claims her leadership is on shaky ground.
Senator Milne was returned to the party's leadership unopposed on Monday, despite a slip in the Greens vote at the September 7 poll.
She confirmed on Wednesday night that six staff members had tendered their resignations including chief of staff Ben Oquist, director of communications Georgie Klug and policy adviser Oliver Woldring, her climate change adviser, her economics adviser and campaign coordinator.
With the spill of Greens leadership the party initiates after each election, all staff positions in the leader's office are automatically terminated by the Department of Finance.
A spokesman for Senator Milne said staff were eligible for a generous redundancy package under this arrangement.

As well, the coalition has indicated it intends to cut the staff allocation the the Greens' leader by up to a third.
"That is further reason for restructure of the office," the spokesman told AAP.
Senator Milne said people had opted to take redundancies for a range of reasons.
"It's quite common in politics after an election for people to consider whether they want to stay on or not," she told ABC TV.
Some staff had indicated last year they would stay with her until the election, and some had given personal reasons for leaving.
She denied the resignations were a vote of no confidence in her leadership.
Mr Oquist issued a statement saying he was leaving with goodwill but cited "fundamental differences of opinion about strategy".
Asked about this, Senator Milne said: "Interesting that Ben would say that," but wished him well in future endeavours.
She said there had been differences of opinion on how the office would run, she favoured a flat administrative structure while he wanted a a more hierarchical structure.
Greens MP Adam Bandt was re-elected the party's deputy leader on Monday, unopposed.
He extended his margin in the lower house seat of Melbourne.
Further comment was sought from Mr Oquist but he was overseas.
