Opposition leader Tony Abbott has attacked the government's border protection policy, its mining and carbon tax, calling it "the worst government" in history.
Mr Abbott made these comments while addressing the meeting of the Liberal State Council Meeting on the New South Wales' Central Coast.
He said the Gillard government is putting asylum seekers in front of migrants with work permits.

He claims those who come to Australia to seek asylum by boat do so illegally.
"We have a government, which has surrendered in the face of people coming illegally by boat and largely going on welfare," said Mr Abbott.
"And to cover up for that capitulation, they are now launching attack after attack on migrants, who come to this country legally to work."
Meanwhile, Immigration Minister Brendan O'Connor says the Opposition should admit its policy will not work after Indonesia's ambassador to Australia ruled out agreeing to the coalition's boat turnback policy.
"The only way that this matter can be dealt with effectively is getting all of the countries from within the region to solve this matter," he told the ABC.
"It will not be done by a slogan; it will not be done by a quick fix. The Indonesian ambassador has made it very clear that the position of the Opposition is untenable."
He says the Coalition should scrap its policy and agree to work on a deal with Malaysia.
On Friday, Indonesia's ambassador to Australia, Nadjib Riphat Kesoema said asylum seeker boats should be turned back to other countries, not to Indonesia.
"Indonesia is a transit country and also the victim of this situation. I think it's not possible for the coalition to say that it has to go back to Indonesia because Indonesia is not the origin country of these people," he told reporters in Canberra.
"No such collaboration will happen between Indonesia and Australia (to) bring back the people to Indonesia."
