It would be fantastic to see this spectacle in Oz. I think Albert park lake would be a good venue as well. It's not only CASA, but Insurance companies will be reluctant to back it. Not to mention the environmental impact study and community consultation over a 12 month period that DOTARS (the real enermy) will force them to undertake.
Would definately go, but I think a trip to the Northern hemisphere will be the only way possible.
