The Minister for Human Services, Cassy O'Connor, said she was disappointed the Tasmanian Liberals were continuing to play politics on the National Disability Insurance Scheme.

Ms O'Connor said the Tasmanian Government fully supported the NDIS, and was continuing to advocate for the State to be one of the four launch sites for the scheme.

"This is a massive reform that will give much-needed support to many people with disability, and it should be above politics," Ms O'Connor said.

"For Jacquie Petrusma to now try to play wedge politics with the hopes and needs of Tasmanians with disability, their families and carers is nothing short of vulgar and offensive.

"We are continuing to state our case to the Commonwealth for Tasmania to be one of the launch sites for the NDIS, and we are making a significant investment in disability services - with more than $175 million allocated in the 2012-13 State Budget.

"By contrast, Tasmanians living with disability and funding for disability services didn't even warrant a mention in the Tasmanian Liberals' alternative budget.

"Jacquie Petrusma and the Tasmanian Liberals need to get serious about supporting the NDIS, and get in touch with mainland Liberal Premiers and their federal counterparts, whose support for the scheme appears to be lukewarm at best."
