With the risk of being viewed as a Turnbull apologist, re: NBN I think he's just trying his best to work with the cards he's been dealt (i.e. compromise).
It is unfortunate that the NBN was one of the key points of the campaign, we all know how it's turning out... It will probably ended up costing about the same, yet without the advantages FTTH brings.
I do hope NBN will come to my area soon (within the next 24 months?), I live about 30 mins away from the CBD, but 4G connection is patchy and I only managed to get 2.5 Mbps on `Broadband`.
