Australian budget walks fine line between growth and austerity

Malcolm Turnbull has repeatedly refused to reveal Treasury costings for the centrepiece of his budget - the 10-year plan to reduce company tax to 25% - saying the figures were included in the general budget forecasts but he was not going to "unpick" them.

Australian Council of Social Services chief Cassandra Goldie also backed the tightening of super tax concessions, but criticised the decision to retain cuts to welfare payments, including the age pension.

The costings muddle has muddied the government's sales job of the budget which is designed to create momentum for the election campaign to be launched this weekend.
