Deputy Liberal leader Julie Bishop says the government's message was resonating so well with voters that Labor abandoned their whole platform and embarked on the Medicare scare campaign.

Ms Bishop said she was on the ground for the eight weeks of the campaign and felt people were listening and responding positively and that the government was winning.

"And so I believed our message was right. But then it must've been right because Labor switched their campaign overnight," she told ABC television.

Mr Bishop said Labor dropped their higher taxes, higher deficits and debt policies and started on the Medicare scare campaign.

"It was a complete switch and then weeks of unrelenting ferocious campaigning to save Medicare, when everybody knew that Medicare was not going to be privatised," she said.

Ms Bishop said the election outcome was still very disappointing and there was obviously a message being sent by the Australian people.

"There's a level of frustration, a level of disillusionment. They want to be heard. They want their concerns heard. Of course, different people have different concerns, but it's a question of listening more, responding more acutely to the issues that they raise," she said.
