The federal government has used the decision of a second ratings agency to confirm Australia's triple-A ratings to increase pressure on Labor to pass its budget savings.
Treasurer Scott Morrison noted the Moody's decision on Wednesday cited risks to its fiscal consolidation plans, which are aimed at saving $6.5 billion.
