@ Minoush Aus had the second highest votes and those votes weren't bought.

I agree with B2D it is a huge country. But I think if Aus won the bid all the games could be held in Sydney alone. We did have the 2000 olympics just in Sydney. As there are enough venues to hold multiple games each day. But for the sake of variety it could be spread out between Sydney and Melbourne. Which is only a 40 min plane ride.
