Climate activists will defy Brisbane City Council by-laws to demonstrate in Queen Street Mall at 4pm today. 

"The city council, who denies the climate crisis, are also denying our right to talk about it,” said Extinction Rebellion spokesperson Rene.

By-laws prevent assemblies with more than 15 people from gathering in the mall. 

“Our planet is undergoing a mass extinction that threatens our existence - we need to talk! Instead, people organising public forums have been penalised with fines totalling over $2,500.”

Today’s assembly will be an open discussion, demanding government act on climate change and reduce greenhouse gas emissions to net zero by 2025.

Extinction Rebellion groups will mobilise in capital cities from March 22 in a week of national action on climate change.
