macarthur coal receives $5.1b proposal, page-25

Even if Liberals came back in Matt77 it would be very difficult to undo the Carbon Tax. Personally think Julia's carbon tax is a great deal. Remember there was all this scare campaign re the GST, loss of jobs, blah blah and guess what? The sky didn't fall in. It is all hot air IMO.
Another thing is that this tax is not only designed to reduce the carbon in our atmosphere it is to encourage are cleaner renewables to be more competitive. That's the crux of the argument IMHO
