international GCN compatibility

If I ordered a gamecube game from the US and had it sent to Australia would it play on my Australian bought Gamecube?

Im pretty sure DVDs have compatibility issues when it comes to different countries.

I can answer that, i'm in AU and order games from the US all the time.
What you need to do is aquire a freeloader disc. Plays NTSC games on your PAL machine and vice versa.
