have a pre-paid mobile so don't need to worry about that

thanks for the other tips though! I have about 3 super accounts (which I have been attempting to consolidate for a couple of years but haven't gotten around to it yet..lol). How do you change electoral roll details? And what about the ATO do I have to change address with them too?
DF is on centrelink's database, it's in his name so will have to remember to get him to change that if he hasn't already.
We can only afford to have mail redirected for a month, I wish it was longer but the money just isn't there.
