Adam Bandt has been re-elected leader of the Australian Greens at the party's first post-election meeting.
Mr Bandt, the MP for Melbourne, will be one of four Greens MPs in the 47th parliament due to open on July 26.
As well, the Greens will hold 12 Senate seats from July 1, giving the party a crucial say on legislation and motions as the Labor government is likely to only hold 26 of the 76 upper house seats.
Deputy leader will be NSW senator Mehreen Faruqi, while Queensland's Larissa Waters will be the leader in the Senate, following a partyroom meeting in Melbourne on Friday.
Deputy leader in Senate is Victoria's Lidia Thorpe, while SA's Sarah Hanson-Young will be the party's manager of business in the upper house and Tasmania's Nick McKim will take on the Senate whip role.
Victorian senator Janet Rice will be partyroom chair.
The position of House Whip was established and will be filled at a future meeting.
The Greens are due to hold their national conference in Melbourne this weekend.
However, Mr Bandt will not be present in person due to having COVID-19.
