Hi, thanks for your reply!
Yes I do know this, when I say move I just mean from England to oz but not permanent yet, I think the whv is better option to start with as I can give it a year living and working here and traveling round abit and using the time to get more Info about permanent move and see if its the right option, if its not I'll have at least given it a year and for the 6 month thing that's why I'm asking about people who may have gone with agencies as some say you can go with them for 12 months and they just move you around hospitals so not going over the 6 months at each.
