Australia Rocks!
A conference there would definitely be good but its got to be long enough to justify the cost.
I recond Sydney would be a decent place to hold it if you enjoyed the city life… Easy excess into the airport, good hotels and great city night life.
If you’re looking for something more Outback, then give Cairns a go. Close to the Reef/ Ayers Rock/ Whitsundays. Its all about nature!
Oh boy… I’m excited now!~
