Anyone know where to get this?

Only through internet or if your local video game store sells import copies. It's just too bad it's not available for the U.S (PAL however, got this by default - luckies)
However, you can help out in this petition - our last chance to bring this version of the game to the U.S./Canadian shores:

from what I know you have to buy the japanese version...I brought FFx-2 in Japanese and English so one I could understand and the other had extras.

If you do want to get the Japanese import then I suggest you get the game script...remember this is information i aquired off the internet.

OMFG did this game get released in Australia!!!
How come i aint seen it down the street

Because this is exclusive to Japan. That's why I feel we should all get it, too. But unfortunately, it was SQUARE-ENIX's (Japan) decision. I think we deserve those updates.

There has been rumours that KINGDOM HEARTS II FINAL MIX+ might come to N. America so...hopefully this means something
