Partners of welfare cheats will be liable for prosecution under a law change announced this afternoon, and could face a year in jail or a $5000 fine.
Associate social development minister Chester Borrows announced three new initiatives to clamp down on relationship fraud in the welfare system, which was believed to cost Government more than $20 million a year.
A new offence will be created to target partners or spouses of beneficiaries who are convicted of fraud.
"Currently there are few options available to prosecute partners who know or benefit from such offending, leaving the entire debt with one partner," Mr Borrows said.
He said prosecuting partners who benefitted from welfare fraud would ensure both parties who profited from the crime were punished, and the debt could be split between the two partners and recovered more quickly.
