It's perfectly permissible right now for the whole of OZ (apparently there are couple isolated pockets in QLD) where it may not be however I think it could be challenged and win in court, a matter of good legal, I suspect.
However, if the distributors get their way in the future that option might disappear, although the last time they suggested it, there was a huge public backlash, that scared the hell out of them.
Batteries are highly unlikely to get cheaper. If government gets involved it will drive the cost up not down, due increased compliance, new other new really idiotic regs, training, stupid additional "protection rules", etc, all getting in the way. Wait and see.
I know for certain in VIC you can disconnect tomorrow, if you want there's not a thing a distributor or retailer can actually do to stop you. In fact contrary to what a retailer might say if you have a smart meter you cancel your account and have it finalised the same day. I've done it and I can tell they really, really don't like it at all. EWOV fixes their boat, quick smart.
Then if you want from there the only cost you would have is a meter abolishment charge, although after a few years they want to come and take them away anyway which they will then do, for no cost
. Done that too
