Mr Bandt will use a speech to the Greens' conference on Friday to reflect on the August 21, 2010, federal election.

The election ended in Labor's Julia Gillard becoming the first female prime minister and governing with the support of the Greens and independents - the first minority government in over 70 years.

The power-sharing agreement delivered a carbon price, children's dental care brought into Medicare and democratic reforms such as the Parliamentary Budget Office.

"When the Greens, Labor and independents worked cooperatively and shared power like we did in 2010, we got a lot done," Mr Bandt will tell colleagues.

"We are facing three crises in this country: an inequality crisis, the climate crisis and now a COVID-induced economic crisis.

"The path to progress is to kick the conservatives out, put Greens into shared power and make the changes we need to tackle these crises."

An analysis of the carbon price policy - which was abolished by the coalition - showed had it remained in place Australia's pollution would be at 465.5 million tonnes a year in 2020 - 12.5 per cent lower than under the coalition.

Farmers would have earned $1.4 billion between 2015 and 2020 and $11 billion over the next decade under the carbon farming initiative.

The Denticare scheme delivered 2.7 million dentist visits for kids, saving parents $1.5 billion.

Mr Bandt predicted the next election could end in a similar situation.

"It could be a re-run of the 2010 election. This is a big chance for action. Shared power and transformative change is possible."

The 2010 election resulted in Labor and the coalition winning 72 seats each in the 150-member lower house, four short each of a majority.

Labor secured its majority with the support of Mr Bandt, as well as independents Tony Windsor, Andrew Wilkie and Rob Oakeshott.
