Australia's prime minister Julia Gillard has defended spending $A12 million of taxpayer dollars on television advertising of her carbon tax, saying it's about providing facts.
The TV ads, starting on Sunday night, are aimed at improving public support for the government's plan to price carbon at $23 a tonne, starting in July next year.
The government plans to spend $12 million on the ads and another $13 million on other forms of advertising.
Ms Gillard said it's the right thing to do, given the amount of misinformation being drummed up by stakeholder groups, big industry and the coalition.
There are reports that industry is countering with a $10 million anti-carbon tax campaign.
