Due to one person with the virus in Sydney, WA Premier Mark McGowan is saying he'll make an announcement over the weekend.
This may lead to a delay in the planned reopening of the WA border to NSW and Victorian residents (i.e. without any need to quarantine for a fortnight).
Some including me may not agree with Mr Alan Joyce (CEO of competitor Qantas) on everything, or many things, but in his describing this sort of reaction as wrong, he's on the ball.
It's a virus. We can't eliminate it, but Premiers (except for NSW) want to pretend they, as saviours, can.
How can any business (including airlines) plan and operate with certainty if there's this stop-start mentality? WA may be affluent due to the iron ore price shooting skywards but we are a Federation not some colonialist backwater as we were in 1899.
