OPPOSITION Leader Bill Shorten is a liar, according to Member for Wannon Dan Tehan.
Mr Tehan hit out at Mr Shorten after he told voters he had "no plans" to increase taxes on their nest eggs despite taking four policies to the election to raise $30 billion over a decade.
"I think what we have seen in the first week of the campaign is Bill Shorten caught out," Mr Tehan said.
"He's telling porkies and doesn't know his own policies."
Mr Tehan said he hoped Mr Shorten would change his tune.
"My hope is that Bill Shorten will tell the truth from now on.
"That's the first lesson from the first week - what we need to see is Bill Shorten telling the truth for once."
Mr Shorten was asked by journalists on Tuesday whether he would rule out "new or increased" superannuation taxes and responded with a general assurance that made no mention of his policies.
"We have no plans to increase taxes on superannuation," he said.
Asked again to rule out change, he said: "We have no plans to introduce any new taxes on superannuation."
When pressed on ruling out new or increased taxes, he said: "Sure."
A Labor spokesman said the party's policy had been public for a long time and Mr Shorten had made clear there were no other changes.
He noted the Opposition was also spending $400 million to increase super fund balances for women and was making sure that recipients of commonwealth paid parental leave would continue to receive super contributions.
