Serious fine defaulters will be targeted with wheel clamps, removal of vehicle licence plates and public shaming under tough new State Government measures to come into effect his month.

Attorney-General Michael Mischin said the new measures, which come into effect on August 21, are aimed at recouping as much as possible of the $259 million in fines unpaid by West Australians.

Under the new laws, which were passed by Parliament last year, defaulters who owe more than $2000 can be targeted, with the 100 worst individuals or companies to be named and shamed on a new website.

There are currently 4976 people owing more than $2000 in unpaid infringements and 9635 who owe more than $2000 in unpaid court fines.

Those people owe $67 million of the total $259 million outstanding.

Mr Mischin said the small “hard core” of offenders were costing the State dearly.

“The rest of the population is having to carry them for their breaches of the laws and failure to pay their fines,” he said.

“The message essentially is that there is a new, enhanced sheriff in town. Either stay out of trouble or be prepared to pay the debt and for fine bludgers pay up before we clamp down.”

Mr Mischin said people could have their vehicles clamped either at their home or in a public place.
