Thanks James. It will all be OK. I am getting married again and also have the twins. So Non-O will be the go. It isn't easy to get a ME Non-O from Australia any more. Because I travel a bit for work i need ME or extensions with re-entry permit.
All foreigners must report their location to immigration by filing a TM30 when their location changes. In some immigration offices it is ok if you are registered TM30 at your wife's house and leave the country, then return directly to the same house there is no need for a new TM30
