Super concession at risk under ALP: Abbott Federal Opposition leader Tony Abbott has warned low-income earners they won't be able to rely on a Labor superannuation tax concession because it's funded by an unsustainable tax. Mr Abbott was continuing his attack on the government amid speculation it could increase super tax concession rates for the very wealthy, saying the step would be a "betrayal." "It is the people's money, it is not the government's money," he told reporters in Sydney on Tuesday. That's why I say to the government, hands off people's savings. Mr Abbott pledged the coalition would not introduce any "unexpected adverse changes" to the superannuation system if it won government in September. "Your money is safe with us," he said. But the coalition remained committed to removing a 15 per cent tax concession for low-income earners funded by Labor's mining tax. "We've always said that benefits that are funded from the mining tax are unsustainable, and because we don't support the mining tax, naturally we can't provide the benefits," Mr Abbott told reporters in Sydney on Tuesday. I've got to say that this offset will be gone under Labor. Let no one for a second imagine that the offset is safe under Labor. It's funded by the mining tax. The mining tax isn't raising any revenue. If Labor wins the election this offset will go. The debate over superannuation has opened up divisions within the federal government, with Trade Minister Craig Emerson saying there was room for debate about the "fabulously wealthy," but senior MP Simon Crean saying he would oppose any retrospective changes. Mr Abbott said Australians were questioning whether they could trust the government on superannuation. "If Simon Crean and Martin Ferguson don't trust this government, why should anyone trust this government?" he asked. Why should anyone trust a government which is raiding your savings to fund its spending? Labor Senator Matt Thistlethwaite told Sky News that talk of change to superannuation was "pure" speculation, and urged people to wait until budget night before making any conclusions. But Dr Emerson on Tuesday again questioned whether it was fiscally sustainable to maintain superannuation tax concessions for high-income earners. "People who are fabulously wealthy are gaining an advantage by putting their money into super while everyday Australians face a tax rate of 30 per cent," he told ABC radio.
