I think Australia will win the series convincingly.
I think you're right. With Warner and Smith back in the team, and Labuschagne hitting form, I think it'll be a tall order bowling them out twice for low enough scores to win. And if the pitches do end up being spicy and low-scoring, I think that our batting line-up will be more fragile than theirs.
We'll need Williamson and Taylor to repeat the series with the bat they had last time around for us to have some sort of shot here.
Think low scoring shootouts are probably our best chance.
Not sure I agree that our batting line up is as fragile. Outside Smith and Warner, not a huge amount to be frightened of (watch Travis Head score three centuries now). Feel like Labuschagne could be vulnerable while the rest of them are on their second or third go in the team. Feel like the drop off from Taylor/Williamson to the rest of our line up isn't as big as the drop from Smith/Warner to theirs. But maybe them being at home changes that balance.
