The high-tech proposal is one of 88 motions which will be debated at the 82nd WA Police Union annual conference in Perth, which begun on Monday.

WA Police Union president George Tilbury said the proposal would involve fitting immobilisers and GPS tracking devices in new vehicles as they are manufactured.

"There is full support within the Police Federation of Australia to lobby the Federal Government for these changes," Mr Tilbury told the union's annual conference in Perth on Monday.
