October 2016 there were 10 supercharger sites in Australia, including 2 temporary ones (Coffs, Euroa). At the end of 2017 there will be 20, plus upgrading the temp ones to permanent. That would seem to be a doubling to me - sorry that the new ones in Bathurst, Nowra, Cooma, Lorne, Ballarat, Horsham, Keith, Brisbane, Gympie & Bunbury don't suit your personal business better. You are still getting your free supercharging but they aren't putting another 2 superchargers in Sydney as a priority.
On the other side, By the end of this year I'll be able to easily drive to Rockhampton in Qld or down to Melbourne, do the great ocean road and drive across to Adelaide all on superchargers. Since delivery of my car in 2014 I have never charged in the Star, and only once or twice at St. Leonards. I've changed more in Pt. Macquarie than in Sydney. The link to Brisbane means I can do a trip to see family there easily, and similarly visit family in SA. If it were confined to Sydney then my car would be much more restricted.
Thank you Tesla.
