Well there is nothing you can do about the console not being able to play Australian games. That's just the way the console was made.
Your console is a JAP console, only works with JAP games. In Australia I believe you will need a PAL console. Here in us we must use the NTSC console.
On every game you will see one of those codes, which tells you which region it is from and which consoles it will work with.
They call the consoles "region locked"
