A $A12 million ad blitz will begins this weekend in Australia to sell the federal government's proposed carbon tax.
The campaign will begin with advertisements on TV networks from Sunday night.
The ABC reports the commercials feature business owners, clean-energy companies and the CSIRO talking about potential investments in renewable technologies.
The government says the campaign will provide the community with clear information about the plan to price carbon.
Advertisements funded by the government will also appear in newspapers and on radio stations around the country.
Meanwhile, Opposition Leader Tony Abbott has raised more questions about the government's carbon tax figures.
At a Liberal National Party conference in Brisbane, he said the government's modelling is based on a price of $A20 per tonne when the starting price is actually $A23 per tonne.
He told the conference that the carbon tax will put the Queensland's economy at risk, particularly in the mining and tourism sectors.
