Treasury modelling published in the May budget expects net overseas migration to fall from 301,000 to 225,000 by the end of the decade. But the opposition frontbencher will advocate for an average annual net overseas migration rate of 180,000 to make up for a shortfall of housing. "Lifting migration standards, and analysing them carefully each year, is crucial to ensure integrity and public trust in our migration settings." "Anything else like mandatory ramps, flattened shower flooring or reinforced walls would be optional extras," Senator Bragg will say. Housing Minister Clare O'Neil brushed off calls from the coalition to cut the construction standards to 200-pages earlier in 2026.
