Vegemite up, if GST rate increased Kevin Rudd warned the price of a jar of Vegemite will rise by about 50 cents if GST is increased. PRIME Minister Kevin Rudd says the price of an average jar of Vegemite will rise by about 50 cents, if the rate of the GST is increased. Mr Rudd was on Friday attempting to warn Australians a Tony Abbott-led government would extend the GST to food, and/or raise the rate from 10 per cent. Based on a higher rate of 12.5 per cent, the price of a carton of eggs would rise by 77 cents, a $4.17 jar of Vegemite would cost $4.69 and two litres of milk would be 54 cents more. "I just think we called it for what it is," Mr Rudd told reporters in Melbourne. All I'm doing .. is saying if that's the case then people should know that that's 50 cents extra on a jar of Vegemite. The opposition has denied it's planning to raise or extend the scope of the GST. If it wins government, Shadow treasurer Joe Hockey agrees a planned broad-ranging tax review could look at the GST. He also says any further proposals would be "taken to the people." But Mr Rudd pointed to John Howard, saying the former Liberal leader had said Labor and the Democrats had punched a hole through the coalition's GST when they took out food. "They are saying loud and clear there's a problem leaving food out," Mr Rudd said. Mr Rudd also said he had not been briefed on Western Australia's budget, which forecasts the state getting a dwindling share of the commonwealth GST revenue. He confirmed Labor wouldn't change the GST or the way GST revenue was distributed. But he argued Mr Abbott appeared to say one thing in WA and a different thing in Tasmania. "In Perth Mr Abbott says quietly to WA folks 'don't worry we are going to change the GST distribution system'," he said. Then (he) runs down to the Hobart and says 'by the way, nothing happening here, I'm not going to change a thing'. Mr Rudd also said he had no plans to change the minerals resource rent tax (MRRT) despite revenues not living up to initial expectations. "I am very concerned about the current state of the global economy and proposing a new tax change to the mining industry now the China mining boom is coming off," Mr Rudd said. He said Treasury has worked through the numbers with the various mining companies, and he is sticking with their advice. Reports also suggest Rio Tinto is asking for a refund on its initial MRRT payments. "What I remember about Rio, in partnership with various other interests in the country, it embarked upon a wholesale campaign to destroy the resources super profits tax as it was back then," he said. I will leave everyone to their own conclusions about the extraordinary campaign of 2010. Mr Rudd also reminded Mr Abbott that he has four days before Treasury and Finance release their independent assessment on the budget and economy with the Pre-election Election and Fiscal Outlook (PEFO) on Tuesday. "Four days ... for him to come clean on the $70 billion of cuts to jobs, health and education he has in his back pocket," Mr Rudd said. Mr Abbott has repeatedly denied that the coalition's budget has a $70 billion black hole, while confirming on Friday that he will be using PEFO to calculate the opposition's election promises.
