Extinction Rebellion activists have locked themselves to the door of Federal Treasurer Josh Frydenberg's Melbourne office and super-glued themselves to the windows, saying they refuse to leave until their demands are met.
The protesters also scaled awnings at the Hawthorn East office and released a number of flares.

Extinction Rebellion activists regularly stage protests around the world to draw attention to their claims of government inaction on climate change.
"Life on Earth is in crisis. Our climate is changing faster than scientists predicted and the stakes are high. Biodiversity loss. Crop failure. Social and ecological collapse," the organisation's website reads.
"Mass extinction. We are running out of time, and our Government has failed to act.
"We have a moral duty to rebel, whatever our politics."
