That is a "at State level of control". States want Fed guidance but then want to be able to pick and choose what they want. Fair enough, the people of that state voted them in to look after their interests, they can change that at any election. If All states but WA open international flights in December that is their right also. Democracy. (Don't like the pollies chances at the next election if other states are open and they are closed.)
Same with the vax and no vax, democratic right. That's the main reason you cannot have 100% vax.
