Anti federalism

At what point does it become attractive for Australia to de-federalise?

Think of all that income tax saved. The states can live on stamp duties, mining rents, and excise charges.

They can each charge their own GST if needed. GST is a state based thing in the US, and that works.

We could de-federalise into a euro model and keep the same currency even.

And just think, we wouldn’t have any federal politics to endure, nor a chief scientist.
