ACT police have arrested 22 people during protest activity at Parliament House today.
Environmental activism group Rising Tide staged the protest in order to call on the federal government to end new coal and gas projects.
The group is also urging the government to introduce a new tax on coal export profits.
A spokesperson for the group estimated around 500 people had gathered on the laws of Parliament House today when the rally began.
They said a smaller group then moved onto the road, where they were issued with move-on orders by police, which some people chose not to abide by.
The spokesperson said a smaller group also entered the lobby of Parliament House.
ACT Policing has yet to confirm what the group will be charged with, saying only that they were arrested over "various offences".
Police said they would continue to monitor the area around Parliament House in case of any further protest activity and respond as required.
Sections of Federation Mall were closed to the public today while the protest took place.
