no no. Some events involve you to go to the movie and to turn on your 3DS to get the event. Australia does not have that kind of shit.
I know what you mean, as I said above
in japan they have events where if they buy a ticket to see the movie sometimes there is a special distribution.
We don't get movie events here in the US either (unless the event is done through somewhere like GameStop), nor do we get the movies in theaters anymore, I think we use to have Pokémon movies in theaters but they just weren't as popular as the big box office movies they can fill more seats with. though Japan has a ton of Distribution events that nowhere else gets.

Specifically, it reveals that Diancie's ability is Clear Body, and states that it can learn moves like Hyper Beam & Explosion, and showcases the new movie poster featuring Diancie with details saying that the movie is "A grand adventure with the princess of the Diamond Mine Country". Not much else is known at this time

A new distribution event has also been announced. Within next month's CoroCoro, a special Serial Code is to be released.
