In my experience 2thick, i would stay well away if i was you. We get thousands of Irish tourists in Sydney each year.....and like many cities, Sydney has it's fair share of Irish pubs which plays host to these tourists.........let me say they are the most average looking women i have ever seen......very friendly mind you, but average to look at (i'm being nice here).
But then it's a matter of taste i guess.
There are some beautiful rsh women, ie The Corrs, but in my experiene they are very average.
