BILL Shorten has told voters to “hold onto your hats” ahead of more big spending pledges, but has refused to release his costings until the end of the campaign. The Labor leader was again grilled over how he would fund the whopping multi billion dollar election spending spree amid claims of a ballooning black hole.

Despite growing pressure over how the promises will be funded Mr Shorten refused to bring forward the release of his costings.

He insists reversing the government’s corporate tax cuts, keeping the deficit levy and changes to negative gearing would fund the spend, insisting he was saving “billions” across the board.

“We’ve said we will stop the rorts in vocational education. Billions of dollars there,” he said.

The government yesterday declared Mr Shorten was spending the same money “several times over”.

Mr Shorten said he would not detail his costings until the policies had been announced.

“There is another four weeks to go in this election so we haven’t unveiled all our policies,’’ he said.

Mr Shorten said he would not detail his costings until the policies had been announced.

“There is another four weeks to go in this election so we haven’t unveiled all our policies,’’ he said.

“When we have unveiled all of our polices at that point we will outline our final costings and measures.”

Mr Shorten said Labor had more key polices to come.

“Hold onto your hats because the next four weeks you will see more positive polices which make a practical difference in the lives of all Australians.”

Prime Minister Malcolm Turnbull seized on the comments yesterday, claiming Mr Shorten’s spend-o-meter was now out of control.
