This one yesterday was from the ABC.
http://www.abc.net.au/news/2014-06-2...-check/5554748Fact check: Tony Abbott overstating household savings from axing the carbon tax
The substance of the ABC's argument is that the carbon price is projected to be lower in 2015/16 than the starting price of $23/t in when it's currently scheduled to become floating price.
It all depends on the timeframe chosen. Go out longer on the forward projections and it becomes an understatement.
