Hollywood star Blanchett under fire

Sydney - Hollywood A-lister Cate Blanchett found herself under fire on Sunday for fronting a campaign promoting the government's planned carbon tax, with critics saying she is out of touch with ordinary Australians.

The wealthy Oscar winner features in a new advert, funded by a coalition of unions and green groups, urging Australians to "Say Yes" to a tax on carbon.

Australians are among the world's worst per capita carbon polluters and Labour Prime Minister Julia Gillard has proposed a carbon tax to be levied on major industrial polluters by July 1 2012.

She then plans a full emissions trading scheme in three to five years.

But the proposals are not popular, with the conservative opposition saying a tax would damage the economy and drive up the cost of living by making energy far more expensive, bumping up electricity bills.

"$53m Hollywood superstar tells Aussie families to pay up", the Sydney Sunday Telegraph blared on its front page, referring to how much Blanchett is worth.

"Cate Blanchett has proved she is just another morally vain Hollywood star trying to justify her great good fortune by preaching to the rest of us about climate change," the paper said in a comment piece.

The Australian Family Association said she was out of touch.

"It's nice to have a multi-millionaire who won't be impacted by it telling you how great it is.

It's easy for her to advocate it, she's one of the people who can afford to pay it," the association said, according to the newspaper.

"There are people who have no comfort zone and no room to move."

Blanchett made no comment but her co-star in the advert, Australian actor Michael Caton, defended his role.

"I'm sure people will criticise me but I thought long and hard and I really believe in this, so I'm speaking up for it," he said.

Earlier this month, a national poll by The Australian newspaper showed earlier this month that 60% of voters were opposed to a carbon tax.

Only 30% of voters supported the plan and 10% were undecided.
