Do japanese games work in australian consoles

ds as in nintendo ds?

I'm hard pressed to say yes, since it's a memory stick type media and I don't believe a region setting would apply. However, depending on the firmware your ds might have trouble reading/showing the fonts properly.

the original DS is not region locked- can play any game

the DSi however, has a region lock for the DSiWare downloadable games, as well as DSi-specific cartridges. But it can still run any DS game from any region

the 3DS is locked for DSiWare, and Nintendo DSi-enhanced software between Japan, America and Europe/Australia

so in simple words, it is region locked if its a DSi/3DS only game
