The Melbourne bid has been "off the ground" since 2002, when a certain S. Boucher was incautious with his remarks and found himself deluged with $20 bills (US or Australian) -- the now traditional way of talking someone into launching a Worldcon bid.

There is no competition against this bid. As long as the A2010 committee keep bidding, I expect them to win unopposed at the site selection election in Denver in 2008.
