I'm focused on Australia's future: Swan TREASURER Wayne Swan says he is more concerned about the future of the country than his own political prospects as he prepares to hand down his sixth budget. A key backer of the minority Labor government, independent MP Tony Windsor, believes Tuesday's budget will be Mr Swan's last, predicting a change of government at the September 14 election. "That's the least of my concerns," Mr Swan told reporters in his traditional pre-budget doorstop outside Parliament House in Canberra. What this budget is about is the future of the country, it's about what we do to keep our economy strong. Whether he was still treasurer after the election would be "entirely up to the Australian people." But Mr Swan remains defiant. "I'll continue to run, proud of what has been achieved and going into the next election that we will win," he said. The treasurer says he has juggled a unique set of circumstances to produce a budget that focuses on jobs and economic growth, while sparing Australians "cuts to the bone." Mr Swan will announce a multibillion dollar deficit for 2012/13 amid revenue writedowns stemming from a high Australian dollar and global financial pressures, rather than the previously forecast surplus. The budget I will present tonight will outline a sensible and methodical approach that puts jobs and growth first, while ensuring we made the responsible decisions to strengthen the budget over time. The budget will take the "extraordinary step" of showing how new school funding arrangements and the national disability insurance scheme, DisabilityCare, will be funded over the next decade. When asked why people should have any more confidence in longer-term predictions, Mr Swan said the forecasts had been prepared by the Treasury, "the same people that did the forecasts for the opposition when they were in government." The budget will also outline further "productivity-enhancing" infrastructure commitments that build on the government's strong record of nation building after years of neglect by previous governments. "We can benefit from being in the fastest-growing region in the world, but we need smart workers and infrastructure to do that," Mr Swan said. This will be a budget that ensures Australia can remain the envy of the rest of the world.
