A surprise move to privatise expert aged-care decisions lacks "logic" and has given NSW's Health Minister major concerns about the Morrison government's approach to the embattled sector.

Aged care assessment teams (ACAT), which include state-employed nurses, geriatricians and social workers, work at public hospitals to assess the level of care required by individual elderly Australians.

The federal government, which funds ACAT, has announced a network of private assessment organisations will deliver it from April 2021, with a tender to be held next year.

NSW Health Minister Brad Hazzard said the decision was not raised with him at a recent meeting of state ministers, nor by federal Health Minister Greg Hunt and Aged Care Minister Richard Colbeck.
