Senator DI NATALE (Victoria) (14:23): Mr President, I ask a further supplementary question. With the carbon tax inflicting such damage on our economy, an economy which is the strongest in the OECD, with low inflation, unemployment of five per cent and low interest rates, why is the government introducing a carbon tax with Australia on the verge of a recession? Senator Birmingham: Mr President, I rise on a point of order. It is a very simple point of order. I draw your attention to standing order 73, which states, at point (f), that questions shall not contain ironical expressions. Unless, of course, Senator Di Natale means the statements that he is making, I suspect his questions have been full of ironical expressions. The PRESIDENT: There is no point of order. Senator Di Natale. Senator DI NATALE: I simply point out that there is no more or less irony than in the statement that the carbon tax was responsible for the death of Fairfax. The PRESIDENT: Senator Di Natale, I will give you the opportunity to rephrase the question. Senator DI NATALE: Thank you, Mr President. With the carbon tax inflicting serious damage on our economy—I would just like to point out it is an economy with low inflation, unemployment at five per cent and low interest rates—why is the government introducing a carbon tax at the best possible time?
