The Baillieu Government has offered an extra $42 million to fund a Victorian trial of the National Disability Insurance Scheme.

The NSW government has also hinted that it will compromise on the NDIS, with Premier Barry O'Farrell's press officer Brad Burden tweeting that "NSW Govt offers to meet PM halfway - puts forward an additional $35m" for an NDIS trial in the Hunter region.

Ted Baillieu told a press conference this afternoon the issue was too important to be a political football and he had written to the Prime Minister to put its offer forward.

He denied it was a political backdown, saying the state government had needed to take some time to assess an offer from the Commonwealth put to it at a meeting of the Council of Australian Government this week.
