hi mate
since i've see its your 1st post here
i strongly recommend you to start clicking the SEARCH tab above
and do your home work, like ALL of us did
'cause all the questions youve asked ...................YES
have been (and still are) covered before a zillion times
just get a coffee or coke or better a scotch (on the rocks)
and sit down & read all that
so you can maybe get a picture of what is like living and working here
nothing like U.S. mate
good luck & good hunting
c ya
