The protests follow in the wake of the latest IPCC report which is warning that the world will pass 1.5C of global warming in around a decade if drastic action is not taken to cut greenhouse gases.
On Tuesday Australian Federal Police responded to a flare being released at a climate change protest outside prime minister Scott Morrison' residence in Canberra.
Protestors were also arrested after spraying climate messages on Parliament House and supergluing themselves to doors.
The messages included "duty of care" in a reference to environment minister Sussan Ley's decision to appeal a High Court ruling finding that she had a duty of care when approving projects that would contribute to dangerous climate change.
A 30-year-old woman meanwhile set a pram on fire outside Parliament saying she "couldn't in all conscience bring a child into the world to face hell-on-earth".
"It's madness that the politicians don't grasp that their children are no safer than anyone else's," she said.
Extinction Rebellion has been targeting oil and gas companies across the globe for years in civil disobedience stunts designed to draw attention to governments and business leaders failing to take action on climate change.
Prime minister Scott Morrison told a press conference this morning that the protests "were not the Australian way".
"The Australian way is not what we have seen with the vandalism in our capital today," he said.
"I don't associate, in any way, shape or form, that foolishness with the good-hearted nature of Australians who care deeply about this issue, as I do and my government does."
Meanwhile former resources minister Matt Canavan described the protestors as "insurrectionists".
Morrison told the media he would not commit to a net-zero emissions target by 2050, but said he would provide an update to the government's strategy before the COP26 talks in Glasgow in November.
"We will meet and beat our targets and we will update what we expect to achieve by 2030, as we always do," he said.
Energy and emissions reduction minister Angus Taylor told the conference that the government has committed A$20 billion to low-emission technologies in the coming years which has been matched in kind by the private sector.
He noted the government has also signed agreements with international partners such as the UK, US, Germany and Japan to collaborate on technologies such as hydrogen and carbon capture and storage.
"We've already signed partnerships…and will continue to do so to make sure these technologies are developed and deployed in ways that allow us to strengthen our economies, create jobs, drive investment and bring down emissions at the same time," he said.
