I don't think Australia's winning run is having a bad effect on cricket at all.If at all, it will help improve cricket all around the world. Also it has not yet reached the proportions of the dominance that West Indies had for well around 12 years. Australia is still a good 5-6 years away from emulating the same and I am sure the other countries will catch up with them.
And Australia has one place where they get beaten...send them to India
That was not true for the West Indies of the eighties.
