Qld announced on Monday they will next rule on NSW Border on 28th Jan, so i dont think anyone was expecting an announcement today.
Anna is free to move Queensland HQ to remote mining camps, but it will be wrong of her to try and force rest of the states to do liklewise or use this as a border requirment. Unlike WA and Qld the other states dont generally have disused mining sites with facilities that can be easily converted. NSW also takes signifiantly more arrivals than Qld so would have to find 4 times the number of sites.
As NSW have proved one of the biggest risks to virus escaping quarantine is during transport to HQ. Replacing a 20 min drive to CBD HQ (or 5 mins to aiport Hotel for flight crew) with a serveral hour drive (or a bus + domestic flight + bus) increased that transport transmission risk.
Apart from the govt sponosred repatriation flights, the commercial flights need to fly to Capital cities because they are mostly carrying freight - the freight is what makes it affordbale for them to keep flying here.
Im all for dedciated Quarantine venues, but think these should be purpose built (with a suitable airstrip and hopsital onsite), not moving the risk to regional NSW which does not have ICU hospital facilities.
