After attending recruitment day here in Sydney, I can share or clear up some details that have been previously posted on here.
The position is permanent in the UK and not a contract; they therefore cannot transfer you here to Oz should you wish to come back and work as CC, you would need to apply; There is no relocation lump sum as far as I know, it was not mentioned in the info brochure; accomodation is not provided.
Still waiting on the confirmation email, agony!
