Whats the backup plan if internal borders stay closed? Business leaders will next push for the PM to hold an urgent referendum on a vote to become a republic. A president elect will then have the power to dissolve states, and the power states have over their own borders.
Yes votes in a referendum from NSW + VIC alone would out number No votes from WA + NT + SA + QLD + TAS.
Lets hope business leaders have a better grasp of how the Constitution and the Australian political system works.
