@ragnel,
Hmmmm......I wonder if they are quietly going to a carbon tax without telling anyone? But electricity is not a federal government supplied thing, so, seriously and all I suggest you guys need to be contacting MPs and media about this issue, as I assume you are likely to be correct and they will raise prices anyway!
I actually don't completely oppose such rises, as they ARE, I think, a pretty good way to lower emissions, but that is not fair.
I need to think about it with our suppliers as well!
I am saving up to pay my $399 bill!
