Convicted terrorists in Australia could be kept in prison after serving their sentences if they are deemed a continued threat, according to new anti-terrorism laws announced by Prime Minister Malcolm Turnbull on Monday.
"We are focussed constantly on the single most important obligation of our government, which is to preserve and protect the safety of the people," Turnbull said.
The process would be overseen by the courts and be subject to periodic reviews and legal appeals, Australia's Attorney-General George Brandis said.
It would be similar to existing laws concerning the detention of sex offenders and violent criminals deemed an ongoing threat.
Under the proposed anti-terrorism laws, the age at which children could be held would be lowered from 16 to 14.
A total 44 people have been charged with terrorism-related offences in Australia since 2014, including some involved in the planning of mass attacks on the public, Turnbull said.
