All the classes I've ever been involved with have gone to there prefered club/location and said please sir/mam will you host my regatta. It would be interesting to see what would fall out of the woodwork if the powers that be agreed in principle that the event would be in Aus in January 201X and then an info/bid pack was given to each club that currently has F16s in their fleet or has a history of hosting this sort of regatta.
