Ive got a lot of time for the Socceroos and Adelaide United and cheer for them but for me I still support England/UK teams all the way in all sports.
As mentioned by others the Aussie cricket team are just wallopers and do themselves no favours.
As for those who moved here and immediately switched allegiances to Australia in all sports over UK I find that strange. You don't just change your team - what happens if your job takes you to Azerbaijan, do you switch again to them.?? I wouldnt think the Aussies would respect that either.
Each to their own though.
