Dozens of extinction rebellion activists have been arrested as protests take place across the globe.
Thirty people were charged with committing offences in Sydney after hundreds blocked a road, while activists surrounded a government building in Wellington, New Zealand.
Fifty people were detained in Amsterdam for erecting a tent on a main road.
Protests by climate change activists are expected in some 60 cities over the next two weeks.
The group is also causing disruption in London, where more than 20 people were arrested on Monday morning.
Extinction Rebellion demands
Extinction Rebellion wants governments to take immediate and drastic action to address climate change.
“We have tried petitions, lobbying and marches, and now time is running out,” Australian activist Jane Morton said.
“We have no choice but to rebel until our government declares a climate and ecological emergency and takes the action that is required to save us.”
Australia’s government has been criticised for its lack of action in tackling climate change but it insists that it is doing its part to reduce global carbon emissions.
More than 20 activists have already been detained in London, with organisers vowing to shut down key sites in the city including the Houses of Parliament and Trafalgar Square.
Similar protests in the UK earlier this year brought major disruption to London and resulted in more than 1,100 arrests.
Protests are expected to spread across dozens of cities, including Delhi and New York, in the days and weeks ahead as activists call for urgent environmental action.
