As the major parties argue over whose budget costings are better ahead of Saturday's election, the shadow of the British exit from the European Union is dominating the economic discussion.
Both Labor and the Coalition have now released their budget costings and both argue that Australia will only be able to have economic security under them.
Mr Bowen says the alternative to Labor's plan would be spending cuts to essential services and could damage Australia's AAA (triple-A) credit rating.
Prime Minister Malcolm Turnbull says it's Labor's plan that could be a threat to Australia's credit rating.
The Coalition says its election costings will improve the budget deficit announced in May by 1.1 billion dollars over four years.
Treasurer Scott Morrison says the Government's 1.2 billion dollars' worth of election promises will be funded by making 2 billion dollars in targeted cuts to improve the administration and efficiency of the entire social welfare system.
But Labor is defending its plan to hit larger deficits than the government over the short term.
Shadow Treasurer Chris Bowen says his party's deficits would be deeper for the first four years, mainly because of Labor's extra spending on Medicare, education and infrastructure
