Adam Bandt will replace Richard Di Natale as Greens leader, whilst Michael McCormack has retained his role as leader of the Nationals party.
Adam Bandt has been elected as the new Greens leader, following the shock resignation of Richard Di Natale.
Mr Bandt, who is the only Green MP in the House of Representatives, was elected unopposed to the position.
Queensland Senator Larissa Waters will remain co-deputy and will share the role with Tasmanian Senator Nick McKim.
Senator McKim defeated NSW Senator Mehreen Faruqi and South Australian Senator Sarah Hanson-Young for the co-deputy position.
Mr Bandt, who holds the inner-city electorate of Melbourne, thanked his colleagues for their support.
He used his first press conference as leader to promote what the party is calling a "New Green Deal" to invest in a clean economy and boost services to address inequality.
"I refuse to accept the dismal standard of this government, led by 'Scotty from marketing', whose love of coal has contributed to these fires that we are seeing at the moment, and the climate emergency we are facing.
"We are a smart and wealthy country, and if we have the guts to take on the big corporations and the weak politicians that they have in their pocket, we can solve these crises."
The Nationals
Michael McCormack says the party will be renewing its focus on regional Australia, after he was re-elected as leader of the Nationals party.
Mr McCormack fended off a challenge from former leader Barnaby Joyce, but did not release the results of the ballot.
"I'd like to think the entire National Party team, and I know they will now unite," Mr McCormack told reporters at Parliament House.
"The fact is, I shook hands with Barnaby. We will move on. We will move on and work hard together."
He said he has been endorsed as party leader "three times in less than two years", which should put to rest any further challenges from Mr Joyce.
"I think that is enough to warrant me leading the party going forward.
"It's a great honour and a privilege to continue to serve as the leader of the National Party."
He said it is now time to end any dispute over the leadership and put the people of regional Australia first.
"We have your back, whether it's drought, we have your back whether it's building new dam infrastructure," he said.
"Regional Australia has a bright future. We will be there to ensure the right policies and the right infrastructure's in place to realise the potential of the future.
It is the first time a Nationals leader has been challenged, prompting a party room vote, in more than 30 years.
