The 70% is just touted as a reward for sydney to go out and get vaxxed quickly, nothing in the plan points to significant changes if for example, the health dept struggling, the spread is too great, certian populations or workers not there yet etc.
No one is opening up at 70%, lock downs don't end at 70%.
At 80% it all depends on the hospitals and death rate
Some time after that WA might let in vaxxed people that have a negative test
Lets face it, it's not a prime destination that the locked down eastern staters want to visit as soon as they're unleashed anyway. They want to go OS, not to WA.
GB, NSW gov, the people and the feds are just having a laugh caring about WAs restrictions, a distraction to blame other states for something - no idea what. And the NSW gov is having a laugh at their citizens dangling a nothingburger 70% target
