Proposed laws that would see high-risk terror suspects behind bars have been labelled an attack on freedom by civil liberty groups.

The federal government is reportedly considering fast-tracking laws to keep high-risk offenders locked away, even after their sentence is served.

He said it undermined one of the key aspects of a free society.

"It's handing terrorists a victory," he said on 3AW Mornings.
