I think it might slip a touch. I had a chat with somebody at St Leonards last week and mentioned that I was planning a SYD-BNE road trip. While we were discussing charging points, he used words to the effect of "it's a pity you're not going at the end of the year". I said "Yeah if I was going in December it would be supercharging all the way". He then appeared to offer a qualifier, responding with "December or maybe January". My *impression* was that he was indicating it might not be fully in place by the end of the year but, IMHO, I can live with January.
