AND do Aussie really need us?
I think this is the big kicker.
Because of Rugby Union and Rugby League it would appear that NZ and Aus comps are great for both nations, but based on the Nix struggles and the Netball issues of the sports deciding us being in their comp doesn't bring enough value, Id find it hard for Cricket Australia to see any value in us being in their comp.
I think it would help us, and I think if they did it right it could be a superb comp that NZ and Aus supporters would enjoy, but I could easily see in a couple of years the whole "what value does NZ bring to our sport" comp, especially with Aus being so dominant.
