All hail the mandate
What always annoys me about politics is the way someone like Malcolm Turnbull can equate winning an election (by however much) with support for every one of that party's policies.
Further, even if some of the population of Australia did specifically vote Liberal on the basis of their revised NBN plan, those people are unlikely to have done so with even a basic understanding of the real technical details, as opposed to just absorbing the endless NBN-bashing colour spreads in the that wonderful paragon or journalistic integrity that is the Murdoch-controlled press.
Which option is the 'best' one, once all has been considered, is still a matter for debate but there can be no doubt that FTTH will provide better speed - especially for uploads - and better future-proofing.
