Western Australia Premier Colin Barnett still has reservations about the National Disability Insurance Scheme.
WA is the only state not to sign up to the scheme in which funding decisions would be made outside the state.
The roll-out in mid-2017 in WA will be a year later than the rest of the country.
The NDIS is supposed to provide better services and funding for people with disabilities, in a way that is more personalised and done through a uniform and national scheme, rather than state-based ones.
Mr Barnett said WA would ultimately sign up to the NDIS but he was being cautious and had concerns about it being swamped by people with disabilities seeking funding who had previously coped.

He did not want to cede control for important decisions about funding that was majority state-based to a bureaucracy based in Geelong, Victoria.
"My prime concern and the prime concern I think of the service providers, the not-for-profit charitable groups in this state, is that we keep that personal care for individuals," he told reporters.
"If all this is run out of a bureaucracy in Geelong, we will absolutely lose that.
"Western Australia will be part of it but we will be hanging out to ensure that we can maintain quality of services and services close to the people receiving them."
