Hi I'm an independent developer located in Australia. I have been developing iPhone/iPad apps since 2008 and don't see any issues in developing your app. Quite coincidently, I have just finished a coaching app prototype for another Australian client. A technique app rather than a game day app.
Don't play indoor cricket, more of a soccer man myself, however I'm a bit of a sports tragic!
If you want to discuss your app requirements with a local and very experience developer please get in touch. Otherwise, if not any feedback on why not should be greatly appreciated.
Steve.
