Hanson migration cuts would cost 'many, many billions' to enforce, ex-official warns

Former immigration deputy secretary Abul Rizvi says enforcing Pauline Hanson's plan to cut temporary migrants by more than 750,000 over three years would cost the budget "many, many billions". Hanson says it would reset the system and ease housing pressure. Rizvi likens the task to Donald Trump's US$170bn operation. Big promise, big bill.
