This will be great for those who want it. I don't. The question has to be - is it going to be optional for those of us who don't want it? By the way, I live in WA and there has been no mention of it here - yet.
I think that it is a matter of Centrelink confirming to the energy supplier that you are in receipt of a Centrelink payment to get the higher payment. I could be wrong, but that is my take on it.
