macarthur coal receives $5.1b proposal, page-26

Why is it difficult ?

If Labor suffers massive landslide defeat, even if the Greens maintains a balance of power in the Senate, Labor will side with the Coalition to dismantle the tax.

By then, Bill Shorten (Combet won't get the job as he is the face of the carbon tax) will tell the Oz Tra Lian Pea Ple that Julia has lost he way and we will jettison the carbon tax.

Bob Brown's balance of power won't come into play.

No need for a double dissolution election.
