Hundreds of people have rallied at Garema Place in the centre of Canberra today as part of a nationwide protest movement expressing a general discontent with the Abbott Government.

Protesters carried signs voicing dissatisfaction with Australia's treatment of asylum seekers, its potential deregulation of university fees, environmental policies, marriage equality and a wide variety of other policy issues.

The one thing that united them was an anger with the current Federal Government.

The crowd was addressed by speakers from several workers' unions, environmental and animal rights groups, refugee-rights activists and Christian organisations.

Organisers said the rally was a non-partisan, community driven event.

"The March Australia Canberra event today is about all of us here, the community, uniting to talk about what's important to us and what's being done in our name at the moment up on the hill," rally coordinator Chris Enrdy said.

"We're making our voices heard, our presence felt here today about multiple issues of mistreatment by our government."

The Federal Government says deregulation of the university sector is essential for the nation's future prosperity.

"The passage of the reform bill will enable Australia to achieve the best higher education system in the world and have some of the best universities in the world," Education Minister Christopher Pyne said earlier in the week while introducing the legislation to Federal Parliament.

Similar protests took place in many of Australia's major capitals and a number of regional centres.

About 29 in total have been held across the weekend.

It follows the March in March protests earlier this year, during which protesters delivered a so-called motion of no confidence in the Abbott Government to Parliament House.
