The RSPT was again the big news story of the day – and for good reason with the chief architect behind the tax, Dr Ken Henry, fronting the Senate estimates economics committee this morning.
Unlike the miners, Henry believes the tax won’t have a significant impact on Australia’s sovereign risk. He also downplayed media reports that the government may be looking to increase the threshold from the bond rate of around 6% to 11%, the rate used for the petroleum resource rent tax.
All eyes will be on Canberra tomorrow when the resources tax consultation panel is expected to deliver its first report to government following negotiations with angry miners and industry groups.
