The main issue is that they will be counted against the international arrivals caps for WA quarantine. So this week, you can knock off 25 for other people returning from overseas. Which may result in some having tickets cancelled...If only our interstate politicians realised that once they exit immigration in Sydney the NZ'ers arriving under the bubble are effectively people in NSW. As long as the same controls apply as anyone who has been in NSW in the previous 14 days, then I'm not sure what the issue is, especially for states that have quarantine arrangements for people arriving from NSW. All that it means, is these people only have to go through 1x quarantine rather than 2!
