Hanson's 750,000 migrant cut carries 'many, many billions' enforcement bill

Cutting more than 750,000 temporary migrants over three years would cost the budget 'many, many billions' to enforce, former immigration deputy secretary Abul Rizvi says. Pauline Hanson says the cut would reset the system and ease housing pressure. Rizvi says the job compares to Donald Trump's US$170bn operation. Big promise. Big bill to match.
