Two things.
The ongoing destruction of Queensland's economy in order to prevent the future loss of such a minimal number of lives is an over-reaction. We have come through the worst of the pandemic and it's time to relax all restrictions nationally.
Having all Australians pay for Qld economic recovery through Federal funding despite Qld shutting out all other Australians is not equitable. Federal bailouts (JobKeeper, JobSeeker) should be based on a national windback of lockouts, restrictions, border closures etc.
Why the focus on Queensland? There are restrictions on entry to most states in Australia. The states with the least restrictions are the ones with by far the largest number of active COVID-19 cases (NSW and Victoria) so it is not surprising that they aren't pushing to not let in people from other states.
By weight of numbers I am sure that the majority of people receiving JobKeeper are in NSW and Victoria.
These restrictions will get wound back as the situation improves/remains good. At every step governments, both state and federal have said that people need to be prepared for restrictions to run a lot longer than they ultimately have. That conservatism seems to be prudent. It helps no one to be making plans that then have to be cancelled whether those are business decisions or personal.
