Victoria will “keep pushing” to make the National Disability Insurance Scheme work, despite a blistering attack on the scheme’s performance by the state Disability Minister Luke Donnellan on Friday.

Mr Donnellan said Victoria was forced to “fund a mirror organisation” to the NDIS just to get disabled people into services, even though the state paid $2.6 billion into the federal scheme this year.

As the bitter funding dispute between Victoria, NSW and the Commonwealth escalated on Friday, Mr Donellan said the federal agency running the scheme was “so bad at service delivery”.

The federal government defended its handling of NDIS finances, accusing the Victorian and NSW governments of a "ridiculous" attempt to grab cash from the scheme’s coffers.
