On the form it asks for your address in the UK. Well I am still in Australia, what do I put? My future employer will give me a month free accommodation to help us settle. Do I write not applicable?

I do not have any family in the UK and it is odd to put a friend's address for the sake of it.

What have other people written in that box?

I booked a self catering holiday apartment for two weeks before coming to Northern Ireland from South Africa so I wrote that address in. I also enclosed with the settlement visa application a copy of the reservation from the holiday place. Get your future employer to put it in writing about the 1 months free accommodation and put that address in the application form with the letter.
