Having been stuck on the wrong side of the international border it is all frustrating, but I don't agree with all the hate slung at WA. The govt there has undeniably kept the virus out, it's saved lives and looked out for WAs interests, and has been resoundingly popular as a result. It might be a bitter pill for those of us overseas and in other states, but ultimately the govt of WA is elected to look out for WA, not the federation, and certainly not the world. I respect their stance, and if I was in McGowans position, I'd do the same. To be honest, I'm more upset with the NSW government, who failed at the critical moment and resulted in a lot of needless suffering in some of our poorest and most vulnerable communities. It's certainly made opening up more fraught and only exacerbated inter-state tensions. Overall, I think it's going to take a while to rebuild trust, both between the states and Canberra, and between the states themselves.

As a territory, I imagine this technically at least, gives Canberra a bit more influence over the border, and might make it more attractive to QF and others in the longer term, who might feel more protected against border closures and disputes there than in somewhere like Perth or Brissie. If the current arrangements go smoothly at Darwin, maybe it'll eventually become the hub everyone hoped against hope that it would
