Sharkie concerned with retrospective laws

A cross bench MP has flagged concerns about the retrospective nature of a Morrison government bill that ensures crime commission investigations are valid.

The draft laws on Tuesday passed the first hurdle of parliament and are expected to breeze through the Senate with Labor's support.

Home Affairs Minister Peter Dutton has assured the opposition the legislation will be reviewed 12 months after becoming law, Labor's deputy leader Richard Marles said.

But Centre Alliance MP Rebekha Sharkie told parliament the retrospective application of the law should be scrutinised very closely.

Ms Sharkie supported the bill with "hesitation" but didn't say if her two Senate colleagues would do so.

Mr Dutton said the measures were technical in nature and wouldn't give the Australian Criminal Intelligence Commission broader powers.
