Working parents, average income earners and Aussies with relatives in aged care are set to be big winners from Tuesday's federal budget. Treasurer Josh Frydenberg will deliver his second budget speech in six months at 7.30pm on Tuesday as he aims to rebuild the economy after the coronavirus pandemic. Mr Frydenberg has already promised more big spending next financial year, with Deloitte predicting a budget deficit of $87 billion, a figure well below this year's estimated $167 billion shortfall. 'We won't be undertaking any sharp pivots towards austerity. We want more people in jobs and in better paying jobs. This is what our fiscal strategy is designed to achieve,' he said in a speech last week.
