I think you misunderstood the Australian ATO publication .. Australia is not accepting BTC as a currency, it's simply doing away with the double taxation on transactions with all & any Alt coins. When i can pay my Government duties in BTC or Alt coins, is the day it will become a currency.. long way off before that happens.
Still it would boost price either way because with the double taxation on transactions using cruptocurrency gonr, many more users from that country might use bitcoin. You are right though in saying it would take a long time before Australia accepts BTC as a currency but the main point of OP here is that price would increase to 3,500 $ in 60 days so let it slide and just wait and see whether OP's prediction will happen or not.
