Surely only the commonwealth government can sign such things not a state government?
"4.5 Section 51(xxix) of the Constitution confers on the Commonwealth Parliament the power to legislate with respect to 'external affairs'. This has been interpreted by the High Court to mean that the Commonwealth Parliament may legislate, under s. 51(xxix) of the Constitution, to implement in domestic law a treaty which has been entered into by the Executive pursuant to its power under s. 61 of the Constitution."
The federal government needs to grow some and shut this mob down.
