The Australian Medical Association fears the Queensland government's unprecedented attempt to stop unions from providing advice to members and its introduction of individual contracts for public hospital doctors could embolden other states to follow its example.

This week, Queensland Health will launch legal action in the Federal Court to stop the AMA, the Australian Salaried Medical Officers Federation (ASMOF) and Together, another union representing senior doctors, from passing on what is says is inaccurate information to its members.

The unions have provided advice to senior salaried doctors about the government's introduction of individual contracts to override collective bargaining agreements.

AMA national president Steve Hambleton said the threat of an injunction against organisations representing doctors was ''extraordinary''.
