Thanks for the reply. I don't think I was clear. The job I have accepted is based in London, but it is with a TV channel that also has a base in Sydney. I know that they do transfer people, but as I've only been there on a short term contract for a couple of months, and only just been taken on as a permanent employee I haven't brought up the subject with HR. So I don't really know if I would be a candidate for transferal at some point. Even if I went the route of transferring, I think I'd need to move into a different role.
Although Charlotte Church may not be to everybody's taste, she is a lot more eligible for the Distinguished Talent visa than I am. That wouldn't be an option for me either.
I'm not sure if it's worth mentioning that my sister and her family live in New Zealand and apparently I have a distance relative who lives in the Northern Territory? I don't think either would make me more eligible.
