More cuts to come, Sinodinos says

Liberal senator Arthur Sinodinos says the tough spending cuts aren't over, with plenty more hard work to come.

The former assistant treasurer says last year's tough budget did a lot of heavy lifting that allowed the government to return some of the benefits in this year's budget, but there is more to do.

"We're going to have to go back to some of the areas we've already cut and cut further," he told Sky News.
