While we can't be sure what the launch lineup for the DSiWare shop outside of Japan will look like, we can guess that the Australian shop will feature at least one of these games, thanks to OFLC ratings:
Master of Illusion Express: Shuffle Games
Master of Illusion Express: Funny Face
Master of Illusion Express: Deep Psyche
A Little Bit Of ... Dr. Kawashima's Brain Training: Maths Edition
The standard ratings board disclaimer applies: we don't know when these will be out, or if this release implies other regions. But if you wanted to know if Nintendo planned to localize any of its Japanese DSiWare lineup, here is evidence that yes, it is.
