Opposition Leader Tony Abbott has labelled the 2011 federal budget a dud that has done nothing to help families with the cost of living.

"It was a dud. I don't think it was worth a mark out of 10," he told the Nine Network today.

"It was probably the flattest, most funereal budget this Parliament has seen in many a long year."

He said the government had failed to address spending and that would put pressure on Australians and on interest rates.

"A government which isn't tough on itself inevitably means more pressure on Australian families," Mr Abbott said.
