The Current State of Mental Health in Australia and Existing Treatments

Mental Health in Australia

Mental health problems in Australia are common. This paper explores the current state of mental illness in Australia, existing and emerging treatment options, as well as the role that social work plays in a treatment team. Mental illness can vary in severity; they can be episodic or persistent over time. Approximately one in five Australians lives with a mental health condition in any one year, equating to 20% of the population (Black Dog Institute, 2020). Furthermore, it is estimated that almost half of all Australians will experience a mental illness at some point in their life (Department of Health, 2020).  The most common mental health conditions in Australia are anxiety, mood disorders (depression, bi-polar) and substance use problems, especially alcohol. One-quarter of Australian’s will experience an anxiety disorder in their lifetime, with more women than men likely to experience anxiety and depression (Department of Health, 2020).

Mental health is a crucial driver to productivity and economic participation in Australia. Mentally ill health can have a potential impact on a person’s social engagement, sense of belonging, community connectedness, and living standards. Mental illness has a significant effect on a person’s ability and morbidity. It is the single most notable contributor to time spent living with ill-health and the third main contributor to total years loss of healthy life (Australian Institute of Health and Welfare, 2016). In 2015, the Australian Burden of Disease Study found that mental illness was responsible for 12% of the total burden of disease among Australian’s, raking fourth behind Cancer (18%), Cardiovascular diseases (14%) and Musculoskeletal conditions (13%) (AIHW, 2019).

The onset of mental illness is typically mid-to-late adolescents, with the highest prevalence of mental illness for Australians in those aged between 18-24 (Black Dog Institute, 2020). Childhood mental health disorders are linked to a range of long-term harmful social, economic and criminal outcomes in adulthood (Young, 2016). Therefore, early intervention and treatment for mental health problems are crucial.


Mental illness is treatable, though, for some people, they may try many different treatment options with limited results. According to the National Survey of Mental Health and Wellbeing 2007, 35% of people that live with a mental illness receive treatment (Australian Bureau of Statistics, 2008). Though, a more recent study conducted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) estimates that the population treatment rate for 2009-10 is around 46% (Whiteford, et al., 2013). There are many barriers to help-seeking, for instance, stigma, cost, access to services, mental health literacy and side effects from pharmaceuticals. There are numerous options for treating common mental illness; the correct treatment can help a person’s condition improve despite the presence of some ongoing symptoms. At times, a person may be confused by their symptoms, mainly if mental health literacy is low; thus, they may not realise that they are unwell, which can delay treatment.

The re-emergence of therapeutic uses for mind-altering, psychedelic drugs has brought the field of mental health to a new frontier in research and the treatment of mental illness. Outlined below are the current treatment options within Australia, followed by a discussion on the emergent psychedelic treatment opportunities around the globe.

Psychological therapy

There are several different types of psychotherapy, including supportive therapy, cognitive behaviour therapy (CBT) psychodynamic therapy, interpersonal therapy, narrative therapy, group, couple and family therapy. Psychological therapies provide people through talking therapies, providing a space for people to talk about their thoughts, feelings and emotions. Psychological treatments can reduce the distress associated with a person’s symptoms or trauma and may be used in combination with other treatments such as medication.


The use of medications is one of the foundation treatments for mental illness. In Australia, the most commonly prescribed medicines are antidepressants, which can be used for anxiety or depression. Mood stabilisers are used for bipolar disorder, and antipsychotic medication is used for schizophrenia or other illnesses with psychotic symptoms. The use of psychotropic medicines is ubiquities (Meadows, 2012). Medicines used to treat common mental illness such as depression and anxiety are also quite imperfect regarding side-effects. Many people experience significant problems, especially with long time treatment (Meadows, 2012). Side effects may include gastrointestinal issues, weight changes, nausea, loss of sexual desire, insomnia, dry mouth and blurred vision.

Lifestyle changes

Exercise is known to help relieve or prevent anxiety or depression, as well as alternative activities such as yoga, meditation, mindfulness practice and light therapy. Avoiding illicit drugs and alcohol is also recommended, as is a healthy diet and proper nutrition. Some studies, such as the SMILES project through Deakin Universities Food and Mood Centre, suggest that the Mediterranean diet can have a substantial impact on mental health.

Community support programs

There are opportunities for people, particularly those living in metropolitan areas to access community support programs, such as peer support groups, Anxiety Support Groups, Social Anxiety Support Groups, Eating Disorder Support Groups.

Emerging Therapy

In the last decade, scientific attention in serotonergic psychedelics (Psilocybin, MDMA, Ketamine) has dramatically increased. Preliminary evidence of clinically studies administering psychedelics in conjunction with psychotherapy have shown robust efficacy in treating trauma-related disorders and some forms of common mental illness such as anxiety and depression (Nichols, Johnson, & Nichols, 2016). In some cases, psychedelic-assisted therapeutic interventions demonstrate momentous and rapid effectiveness in the treatment of severe mental health problems that rival existing pharmacotherapy treatments (Hutchison & Bressi, 2020).

Social Work

Social work is a discipline dedicated to the advancement of social justice and promotion for social change. Thus, social work should continue at the forefront of treatment innovations for pervasive and chronic mental illness. Social workers are experienced and accustomed to working with clients in tandem, providing support, advocacy, guidance and psychoeducation on the use of traditional psychoactive medications treating mental illness (Hutchison & Bressi, 2020). As a profession which is committed to the healing, empowerment and health of communities, the field of social work has a unique role to play in the research, education and engagement of psychedelic-assisted therapy.


Mental illness is common; one in five Australians will live with a common mental illness in any one year. There are numerous treatment options available, though only 35% of people receive treatment. Medication is often prescribed by a treating physician. However, adverse side effects are one of the driving reasons why people stop taking medication. With prevalence so high, we need a paradigm shift to explore alternative options for assisting people who live with a mental illness.
