A clinical psychologist undertakes specialist training to assist people with psychological difficulties such as depression, anxiety, stress, relationship and parenting difficulties, grief, work strain and adjustment to adverse life events, such as change and loss. Broadly, clinical psychologists assist people by providing assessment, diagnosis and treatment which is supported by research, known as evidence-based interventions. Evidence-based interventions commonly used are Cognitive-behavioural therapy (CBT), Interpersonal Therapy (IPT), and Acceptance and Commitment Therapy (ACT).

Clinical psychologists are frequently part of a health care team that collaborates to achieve the best outcome for the person and his/her significant others. When individuals are referred to a clinical psychologist under a Mental Health Care Plan, clients are eligible for a Medicare rebate. The clinical psychologist then liaises with the referring general practitioner, psychiatrist or paediatrician at regular intervals.
