Topic: What region?

Ok just going through this site and I was wondering. What region is everything referring to?
Sometimes it will say US or EUR (I know what they mean that's not the problem) but I can't find any reference to Australian (PAL)
release dates or releases. I don't even know what day games are released for DSiWare (I just got mine online friday and they
haven't added any new games yet). Clarification would be most welcome.

Ok first most people from here are in NA,EU,AU.
And second new games dsi shop channel come on Fridays for Au.

Thanks

Your welcome
