The mining industry in Australia has launched new advertisements warning the federal government not to impose further tax increases.
The ABC reports the industry spent more than $A20 million on an advertising campaign targeting the Rudd government's original mining tax.
It pulled the ads after Julia Gillard took power and negotiated a new mining tax with the industry.
Now the Minerals Council of Australia has taken out full-page newspapers ads warning about further potential tax hikes for the resource sector.
The council says the industry is not a bottomless pit and that it already pays 500% more taxes and royalties than a decade ago.
The ABC says there is speculation that mining companies will be stripped of diesel fuel rebates and other tax concessions in the next budget.
