Layman,
why would NSW need a roadmap or timeline for opening their border?.....Their borders are all ready open, with the only restrictions being to those that have been in Victoria within the last 14 days (with exceptions for Border residents etc). They are even allowing International NZ arrivals.
And fair in enough re restricting those who have been in Victoria. Even the Victorian Government is still cautious as to whether they have Covid under control or not......the Melbourne Metro still has the 25 mile “RIng of Steel”, so why would NSW allow unimpeded travel from Vic?
