So when the Libs win, Turnbull may actually start sharing his real thoughts on the NBN. He might propose something closer to Labor's infrastructure, or at least something better than the Libs current policy (anything would be better really).
He could even be a dick about it and wedge Tony on the matter like what the Libs did to Turnbull with climate change policy.
The voters that are all pissy with Labor can have their short moment of satisfaction when they're ousted from office. After that, we all expect the replacement PM to be pretty awful in his first term even if the papers keep propping him up.
Turnbull actually made the party backtrack from ripping it all up to what they have now. I get the impression that he thinks it is a good idea but the party is using it as a phantom bogeyman to win votes.
My landlord is the lead engineer for the NBN in my local area. He say that the contracts are signed for everything and too much work has already started, he thinks there is very little they can do to change it at this point.
