Senator DI NATALE (Victoria—Leader of the Australian Greens) (14:20): Mr President, I ask a supplementary question. I thank the minister for his answer, and there is a sprig of wattle coming his way. The Parliamentary Budget Office costed the Greens' progressive superannuation policy, which broadly offers a 15 per cent deduction below marginal tax rates, as bringing in $8.7 billion over the estimates period. I seek leave to table that costing. Leave granted. Senator DI NATALE: Is the government prepared to fix these unfair tax breaks and work with the Greens before these tax breaks cost the budget more than the entire pension expenditure combined?
