I've never tried it, but to use the Internet I think you'd need some central server to connect to - a server that would host the game, that is.
What me and my mates do is pick one persons house and we all rock up with our Xboxes, network cables, a hub, TVs/borrowed projectors from work and go wild for several hours.
Basically it's all about Location! Location! Location! You need the participants to be relatively close to each other (same city at worst) so we can have the LAN somewhere. The fact that your Location field is blank is the first stumbling block!
We need to get people from the same city to play.
However, if we had at least one uber-geek in each city, we might be ale to set up a LAN in a persons house (with cable/DSL internet) in Brisbane, Melbourne & Sydney (and/or wherever else) and set up a VPN between each so it looks like one giant LAN. Then all the XBoxes should see each other. Never tried it though... :s3 But as all IT people say... it should work!
Having said all that, I need to add that I suck at Halo so unless others are pretty hopeless I don't think I'd participate. I always struggle with the controller - I'm used to using a keyboard and mouse where I can program all my own keys. Count me in for a Counter-Strike LAN though!
Getting back to the LAN, if you wanted to go really feral, we could do our own DreamHack. I got these pics from a friend a while ago. Enjoy!
And now the phun phacts:
