I’m a huge believer in international competition. One country's best up against another country's best. Which isn’t really the case at the moment if we were honest.
Letting anyone play for whoever they want clearly isn’t a good thing and defeats the purpose of international competition. As for a fair go in their home country? This is going to sound harsh but… tough shit. Luck of the draw where you were born and grew up.
As for supporting Non-Australians at the Olympics? Well I’d never want them to represent Australia in the first place let alone support them if I was honest. It just doesn’t feel the same.
We can all turn a blind eye on one or so once and awhile playing but the ‘English’ cricket team are pushing the boundaries right now IMO.
As long as cricket is the only international sport you follow. You will be ok. Australia tends to only pick Australian born players. Nannes was a bit of an anomaly. He never thought he would be picked for Australia so he used his parent's nationality to play international cricket for The Netherlands. Clarrie Grimmet (NZ) and Kepler Wessells (SA) were a long time ago now.
If however you follow virtually any other sport, then you will be disappointed.
The Wallabies have Pek Cowan and Sekope Kepu who were both born in NZ with Kepu playing for the NZ u21's before he came over here. David Pocock is a Zimbabwean and Stephen Moore is born in the middle east of Irish descent !!!!
Turn a blind eye?
Not when it is England, and when England are playing well and winning.
