Can anyone tell me what are the pro's and con's to moving to Australia.

We're currently in the process of considering emigrating to Australia, so that our two Daughter's have a better future, than here in England. My Brother-in-Law emigrated last year and seem to have settled well.

I would like an unbiased opinion from anyone who is living in Australia, i.e., would you come back to Blighty or is everything greener on the otherside?
