Williamson and Taylor are looking very confident and they are playing fantastic cricket, it can be projected that, NZ will score over 300 easily, since this pitch is totally batting favored so Australia will also bat comfortably, in the pitch, bats man is getting full favor, so it's going to be a big score match.
If Williamson continues to hit like this then there is no doubt that New Zealand will cross 300. I think it'll be a competitive match as Australians too in great form. Let's see.
My bet is for NZ right now
