I think NSW and SA will be considered the same from a NZ perspective. NZ needs the hotspot definition to work otherwise they have no certainty about intra/interstate movement in Australia.Currently given we have been locked out of Victoria for so long I can't see why the border needs to be open just yet. NSW has only just opened and their case numbers have been controlled for some time. Just too many unknowns and let's just say my confidence with management just isn't there right now. SA is open to all but Victoria and has no active cases in the community and hasn't for weeks now but it seems to be ignored when it comes to the NZ bubble so if NZ dont want us then not interested.
The big question will be if NSW opens to regional VIC then metro VIC, what will SA do? I think SA and NSW will have to follow the same opening path from now on - otherwise there is no point having the SA border closed to VIC when you can bypass it via NSW.
