Not sure why anyone really cares about WA borders. The flying is marginal profits, QF has already organised re-routing for international. At the end of the day the state can do what it wants, the population there supports it, so yelling at them to open up is like screaming at China to comply with something. They won't and will probably stay closed longer in spite of being told what to do.
In other news, does anyone else find it convenient that an anti-vax group specifically targeting Michael Gunner in the NT appeared a day or two after his smack down of Ted Cruz. Shouting his address and suggesting action be taken against him and his family. It reeks of another countries method of politics being wielded here.
