Considering Betfair is still new here and with new punters joining every day, it will take a while for things to settle down. I doubt Poms being smarter [they wish] than Ozzie's has anything to do with it. They are just more familiar with Betfair and Laying, that's all.

They can't play cricket [they have been at it longer than we have] and are equally hopeless at most other international sports. I doubt they are especially good at punting either!
