Banks are about profit. They are not going to have interest rates lower then what they will have to pay for money from overseas. If there is not a couple of percentage points in the deal then they won't lend. Either the higher rates or the lack of capital available will be the straw the breaks the back. I doubt gillard will get the carbon tax through if she does we will be the laughing stock of the whole world and all those silly Irishman jokes we use to say would have an Aussie in there instead.
