Well that’s the whole point of borders - a defined boundary of governance. Of course Queenslanders are still Australian. But states are allowed to erect border closures, that’s their right. And considering Palaszczuk got re-elected on a bigger margin by doing just that, it seems like locals of Queensland have formed the opinion that border restrictions are necessary. Yes, inconvenient, but necessary to protect public health. NSW closed the border with Victoria and successfully kept out a second wave.
