Human Services Minister Cassy O'Connor said those attending the meeting would discuss a preferred design of the scheme, which was similar to Tasmania's system known as Gateway.

``The model that we're looking at I'm really proud to say is very well aligned with the Gateway model, which is why we have an excellent chance to be one of the launch sites. That is part of the discussions, but both (Premier) Lara (Giddings) and I at the table have already made it very clear that Tasmania is keen to be a launch site.''

Ms O'Connor said ministers would debate what the insurance scheme should look like, how it should work and who should be eligible.

``But the most fundamental question of all, in the minds of the states, is: How will it be funded?

``That's been a bit of a sticking point at the ministerial level to date . . . (and) that's why it is important to do the design work while we continue to have that conversation around resourcing.''

Tasmania's disability services budget is about $160 million which supports 6500 people, and a Productivity Commission report estimated that would need to double under a national scheme.

``We're really keen to be a co-operative player at the table, but we have raised the issue of the funding source and those funding questions because they are real and they are pressing,'' Ms O'Connor said.

``I have no doubt at all that every single state and territory will say: `Show us the colour of your money' (today) as they said at the last ministerial council meeting.''

The scheme is due to be launched at trial sites next year.

The Tasmania Disability Lobby is pushing for the state to lead a trial of the scheme.
