I think it's only going to Japan for the Asia Pacific area?

You could always take a family trip to Denmark. I was supposed to go there last year but I didn't end up going to Sweden. Lego Land is actually a bit far from Copenhagen, so if you go it would definitely be a whole day trip.

i don't know about australia, but little boys here in the states are wild about Legos.  if you can take him to see it, don't miss it!

Sorry don't know much about lego but if you go to this lego site you may be able to find some info there and if not I am sure you will be able to write to someone. 

Hope this helps you out
