AUSTRALIANS have turned on the carbon tax, with almost two-thirds of people opposed to pricing greenhouse gas emissions and an overwhelming majority backing Coalition plans to unravel the policy.

The findings confirm Australians are far less concerned about global warming than five years ago, with only a third of Australians supporting aggressive measures to tackle global warming - down from more than twice that figure in 2006.

The indication of public attitudes emerged in a snapshot of Australian opinion on key international issues in a poll conducted by the Sydney-based Lowy Institute. It finds people are tetchy about the changing world - sour on foreigners buying up Australian farms (81 per cent), and fiercely opposed to taking a global lead with the carbon tax (63 per cent).

But on other contentious issues the government has more support.

Australians are happy to see foreign workers imported on temporary visas to meet labour shortages, with almost two-thirds of people surveyed backing the import of overseas workers when companies in Australia cannot find enough local skilled labour.

The survey of 1005 people was conducted in late March. The government appears out of step with public opinion on Prime Minister Julia Gillard's push to sell uranium to India, with more than 60 per cent opposed.

Arguments that nuclear power is a clean alternative to fossil fuels would appear to have little chance, given the big drop in support for measures to tackle global warming.
