Bill Shorten says he will work with, but not for, business should Labor win the July 2 election as he continued his attack on the Turnbull government's planned corporate tax cuts.
His comments came as a former Queensland state Labor treasurer accused the opposition of running an anti-business campaign.
Keith De Lacy said the opposition's stance on corporate tax cuts was the "most anti-business policy I've ever seen federal Labor put to an election".
Mr Shorten is not for turning in opposing the $50 million tax cut plan.
"Labor will work with business, but we won't be for business," he told reporters in Cairns on Monday.
A Labor government would operate in the interests of all Australians and won't be dictated to by business if it meant jeopardising Medicare and bulk billing.
Finance Minister Mathias Cormann jumped on Mr De Lacy's comments.
"Bill Shorten and Labor are running on a unity ticket with the Greens pursuing an anti-business, anti-success, anti-investment, anti-jobs, anti-growth agenda ... a former Labor treasurer from Queensland agrees," he told reporters in Canberra.
Opposition finance spokesman Tony Burke dismissed Mr De Lacy's comments, saying they were nothing new.
"If you want to deliver economic growth, you don't just throw all the wealth to the top and hope some of it might trickle down," he told reporters.
"It is a theory of gravity but it's not good economics."
