This has been an unmitigated failure of leadership starting at the top. The pain caused to all by poor policy decisions is decimating our country. The current loop of failure and blameshifting by our " Leaders " is simply shamefull.Pi$$ them all off and start again.
The only way to fix it would be to convene Federal Parliament and pass a bill for the State Borders to be Federally Controlled. It would then be WW3 between the State Labor Parties and the Liberals. There would probably be a constitutional challenge in the High Court which could go anywhere. Canberra was angling to take control of the borders in the beginning but that was ended by the Clive Palmer Court case.
