your nz my aus?

well what about 3:1?

Not at 3:1 considering Australia won the Tri Nations.

well, what do you propose?

it's in new zealand, they steamrolled tonga in their 1st game and oddschecker has them around 2.89 : 1

I wouldn't call that steamrolled. If they play like they did in the 2nd half again they wont make it past the quarters.
Game of the Tournament so far: France vs Japan.

you don't have to call it steamrolled or crushed, i do. in the 2nd half they just did what they had to do, the game was decided already - 29:3 at halftime!
anyway, i think 3:1 is a fair offer...

2:1 is fair.

Australia 1/4
New Zealand 1/9

That's after New Zealand's first game as well.

2:1? rofl, i'm out, where do you have these odds from?!?
