Greens leader Christine Milne has lost all of her senior staff in a post-election shake-up that has exposed rising tensions inside the minor party.
Following an election that sent the Greens' Senate vote backwards, there has been a mass exodus of senior advisers, with some privately citing dissatisfaction over the direction of the party and its poor campaign strategy.
A 4.5 per cent Senate swing against the Greens and a 3 per cent negative swing in the lower house had the party shed more than 400,000 votes at the election and has sparked a round of internal recriminations and soul searching.
Senator Milne's highly regarded chief of staff, Ben Oquist, quit this week amid suggestions he had too many differences of opinion with Senator Milne.
''He left on good terms, but Christine wouldn't take his advice and he got tired of that,'' one Greens operative said.
Ms Milne confirmed on Wednesday night that six staff members had tendered their resignations including Mr Oquist, director of communications Georgie Klug and policy adviser Oliver Woldring, her climate change adviser, her economics adviser and campaign coordinator.
''It's certainly true that people have opted to take redundancies but that's for a range of reasons,'' she told ABC TV.
''It's quite common in politics after an election for people to consider whether they want to stay on or not.''
Some staff had indicated last year they would stay with her until the election, and some had given personal reasons for leaving, Senator Milne said.
She denied the resignations were a vote of no confidence in her leadership.''There's no panic or nothing to be concerned about,'' she said.''This is pretty normal for political offices.''
Mr Oquist responded to questioning via text message, saying he resigned to pursue interests in the business and community sector.
''Left on good terms but fundamental differences in opinion in strategy had emerged.''
Senator Milne said there had been differences of opinion on how the office would run, she favoured a flat administrative structure while Mr Oquist wanted a more hierarchical structure.
''I wish Ben very well with his endeavours in the future,'' she said.
