Thousands of Australians are joining global rallies calling for strong climate change action ahead of the Paris climate talks beginning next week.
Protestors gathered on Sunday in Sydney, Canberra, Perth, and Hobart to show support for a strong stance from Australia in Paris and a global compact to deal with climate change.
Tens of thousands gathered in Melbourne on Friday
600 other cities around the world, from more than 120 countries, are also playing host to climate rallies over the weekend.
In Canberra, around 5,000 came together to demonstrate at Parliament House.
"Often at these climate marches it can feel like we're protesting something that's so hard to change but the reality is that there is so much climate action already happening right across the world and here in Canberra's a great example of that," ACT Conservation Council’s Phoebe Howe told the ABC.
"We're excited to celebrate that and to invite everyone participating today to find ways they can stay involved and keep pushing so that together we can find that global solution."
Thousands have gathered in Sydney where protesters will march from the Domain to the Opera House.
These demonstrations follow previous rallies over the past few days in Melbourne, Brisbane, and Darwin.
Melbourne's rally attracted tens of thousands of people -- crowd organisers put the figure at around 60,000 though police said at least 40,000 people attended.
"This absolutely is the largest climate change rally we have ever seen in Australian history," rally organiser Victoria McKenzie-McHarg told the crowd.
Most Australians want the federal government to push for larger cuts to greenhouse gas emissions at next week's UN Conference on Climate Change in Paris.
A November Lowy Institute poll found 62 percent of Australians want the Turnbull government to take a stronger position to the talks than its current target.
On Saturday Prime Minister Malcolm Turnbull encouraged Commonwealth leaders to signal to other nations that strong climate change action is needed.

The Federal Government has committed to a 26 to 28 percent reduction in Australia’s greenhouse gas emissions by 2030.
In comparison, Labor has set a target of a 45 percent reduction in emissions by 2030, a goal that’s been labelled as "mad" by government frontbenchers and "heroic" but unaffordable by Mr Turnbull.
