The issue of whether a person is unfit to plead or to stand trial is discussed in Kesavarajah v The Queen (1994) 181 CLR 230 which applied R v Presser  VR 45. See also Eastman v The Queen (2000) 203 CLR 1 and the references to practice books at [4-310].

“Procedure for fitness to be tried and mental illness cases” at [4-325]ff provides a detailed checklist and procedural information where unfitness is raised, and appropriate orders under the Mental Health (Forensic Provisions) Act 1990 (NSW).
Generally, the procedure to be adopted where the question of the accused’s fitness to stand trial arises is to be found in Pt 2 Mental Health (Forensic Provisions) Act.
If the issue arises it is to be determined by the judge alone: s 11(1). The judge is to give reasons for the determination including “the principles of law applied” and “the findings of fact”: s 11(2).
