A new poll shows a majority are happy to pay a levy for the disability insurance scheme. MORE than 50 per cent of Australians support increasing the Medicare levy to pay for the government's disability care reforms. But in a blow to Prime Minister Julia Gillard, a Seven News/ReachTEL poll has found about 41 per cent are less likely to vote Labor because of the announcement. A day after Victoria became the fourth state to sign up to the scheme, Ms Gillard said her government would "keep working hard" to make DisabilityCare Australia truly national. "I think the momentum is with us now to get this as the national scheme and I'll keep talking to the premiers of Queensland and Western Australia, and of course the chief minister in the Northern Territory ... to try and get agreement around the nation," Ms Gillard told ABC television. The Seven News poll released on Sunday night revealed 52.5 per cent backed increasing the levy by half a percentage point, with 33.5 per cent opposed and 14 per cent undecided. Of the 2856 people polled, 26.4 said the announcement made them more likely to vote Labor, while 41.2 said it would make them less likely to back the government. And despite her key role in pushing through the reforms, only 42.7 per cent said they trusted Ms Gillard to best deliver the disability scheme. Opposition Leader Tony Abbott had the trust of 57.3 per cent. Ms Gillard last week announced an increase in the Medicare levy to two per cent, to raise $3.2 billion of the $8 billion needed each year for the reforms. On Sunday she said the levy increase should be permanent, and not scrapped when the budget returned to surplus.
