I'd like to recommend Paper Mario: The Thousand Year Door. It's funny (I thought it was funnier than Inside Story, IMO) and the battle system is elegantly simple (most damage is in single digits, you can see enemy HP, so you can plan out battles well), as well as Mario being more customizable as the game goes on due to the badge system. I'm currently playing Bowser's Inside Story and I still think Thousand Year Door is better.
The only problem is that cutscenes are unskippable.
Also, try the Phoenix Wright: Ace Attorney series (starting from game 1). The first game is the best, along with the 3rd game, but the second game has a very good concluding case (do NOT spoil yourself about it, whatever you do) if you get discouraged by it.
Note that I don't know of any of these games' availability in Australia, but you should be able to find Thousand Year Door (and possibly Phoenix Wright), as it isn't rare that I know of.
I hope this helps!
