New laws which will allow police to demand computer and phone passwords from certain offenders could violate fundamental rights, a civil liberties group argues.

Police Minister Mark Ryan introduced a new bill on November 29 which would allow police to demand passwords and access codes for electronic devices from reportable offenders where there was a suspicion that an offence had occurred.

The law would cover reportable offenders who have been released from government detention or sentenced to a supervision order in the preceding three months, convicted of a prescribed internet offence or having been assessed as posing an increased risk of re-offending.

Reportable offenders include people who have been convicted of child sex offences and who are required to report to police.
