The policy, announced on Tuesday, would reduce net overseas migration to 100,000 for two years, then to 130,000 in the third year and 160,000 in the fourth. Taylor and Deputy Liberal leader Jane Hume have said the Coalition "worked closely" with the PBO on the plan, but Coalition sources told Guardian Australia the independent budget watchdog had not conducted a full analysis of the new policy before its release.
Taylor's office said they planned to have the policy costed before the next federal election, using internal analysis and existing costings during the design process. A policy document said the Coalition had worked with the PBO to assess "the impact of the package on the budget," finding it would generate a small positive return.
Challenged over the release of PBO costings on Wednesday, Taylor told Channel Nine: "We've released the outcomes of that budget analysis that we've been doing." The PBO declined to comment on Wednesday. PBO officials are not allowed to discuss costings for members of parliament but can choose to clarify references in media reports if they are incorrect or misrepresent PBO work.
Business and the university sector have warned the cuts are arbitrary, dangerous for the economy and likely to exacerbate shortages in key sectors, including health and aged care. Labor and One Nation both want to bring down international arrivals, seeking to capitalise on growing anti-migration sentiment and pressure on housing and essential services.
