On right path for AAA rating: Treasurer

Treasurer Scott Morrison is confident the government is making the right policy decisions to maintain its triple-A credit rating.

Global credit rating agency Fitch confirmed Australia's AAA rating this week, but warned it could be downgraded if there was a sustained widening of the fiscal deficit leading to a continued upward trajectory in government debt.

"Those on this side of the house have policy actions to ensure we remain on that credible and solid path to ensure we are reducing expenditure," Mr Morrison told parliament on Thursday.
