Hunger, or undernourishment, is a significant issue globally and within Australia. Undernourishment is defined as consuming less than the energy required to maintain an active and healthy life. While Australia is a developed country with a relatively low prevalence of undernourishment, it is still a concern for a small percentage of its population. According to recent estimates, around 2.5% of Australians were undernourished in 2022, with certain groups, such as Indigenous communities and older adults, being more vulnerable. This issue highlights the importance of addressing food insecurity and ensuring equal access to nutritious food for all Australians.

What You'll Learn
Food insecurity in Australia
Food insecurity is a pressing issue in Australia, affecting an estimated 5% of the population. While it may be more commonly associated with developing nations, food insecurity is prevalent among specific groups within affluent countries like Australia. Food insecurity has three main dimensions: inadequate access to food, insufficient quantity, and improper food usage, such as inappropriate preparation methods.
In Australia, certain demographics are more susceptible to food insecurity. For instance, unemployed individuals, single-parent households, low-income earners, and renters are more likely to experience food scarcity. Additionally, remote communities often face limited food supplies, with prices for groceries being significantly higher than in urban areas. This issue disproportionately affects Indigenous Australians, who may also struggle with inadequate household infrastructure, overcrowding, limited access to transportation, and insufficient storage and cooking facilities. As a result, they may rely more heavily on ready-made meals from fast food outlets, which may not provide adequate nutrition.
CALD (Culturally and Linguistically Diverse) groups in Australia also experience food insecurity due to a departure from their traditional diets. When relocating to Australia, they may struggle to navigate the unfamiliar food environment and fail to adopt nutritious alternatives. This transition can be challenging, especially without adequate nutritional education about the local food options.
The impact of food insecurity on children is particularly concerning. Child and family services organisations play a crucial role in mitigating food insecurity among their clients by offering practical measures and referrals to services like financial counselling. Addressing food insecurity is essential to ensure positive outcomes for children's academic performance and long-term health, reducing the risks of obesity, diabetes, and heart disease.
According to the Foodbank Hunger Report 2023, an alarming 3.7 million Australian households ran out of food in the previous year, underscoring the significant challenges posed by food insecurity in the country.

Indigenous Australians at risk
Australia is a wealthy country, but evidence suggests that food security among Indigenous Australians, including Aboriginal and Torres Strait Islander peoples, has not been achieved. Food insecurity among Indigenous Australians has a long history that began with the colonisation of Australia and has since been exacerbated by government policies and economic influences.
Indigenous Australians living in remote, regional, and urban parts of the country experience food insecurity for various reasons, including low income, welfare dependence, and a lack of access to affordable and healthy food. This has led to a higher rate of illness and disease among Indigenous Australians compared to their non-indigenous counterparts, directly related to food insecurity. Poor nutrition has been linked to poor individual and community health outcomes, contributing significantly to the total burden of disease for this population. Diet-sensitive chronic diseases are estimated to account for 80% of the mortality gap between Indigenous and non-indigenous Australians aged 35-74.
The Australian Bureau of Statistics estimates that Indigenous males born between 2005 and 2007 have a life expectancy of 67.2 years, 11.5 years less than the expected 78.7 years for non-indigenous males. Similarly, the life expectancy for Indigenous women born during the same period is 72.9 years, a full 10 years less than the expected 82.6 years for non-indigenous women.
Food insecurity among Indigenous Australians varies in severity across the country, affecting 20-25% of the population. In general, it is estimated that between 4% and 13% of the Australian population experiences food insecurity, with specific populations experiencing higher rates: up to 90% for asylum seekers, for example.
The Australian government has made efforts to improve food security for Indigenous Australians, particularly since the early 2000s, but large-scale, structural solutions are required to address the underlying causes of food insecurity in these communities.

Factors causing food insecurity
According to the World Bank, 2.5% of Australia's population was undernourished in 2022. While this figure is significantly lower than those of developing nations, food insecurity is still an issue in Australia, with certain groups experiencing unequal levels of security in relation to food.
Food insecurity refers to inadequate access to food, inadequate supply, and the inappropriate use of food. Here are some factors that contribute to food insecurity in Australia:
- Socio-economic status: Low-income families often struggle to purchase adequate quantities of food and ensure nutritional quality. This is particularly true for single-parent households, the unemployed, and those relying on government financial assistance.
- Geographic location: Food insecurity is more prevalent in remote communities, where food supply is often limited and expensive. Indigenous Australians living in remote areas are especially vulnerable due to poor income and limited access to transport, storage, and cooking facilities.
- Cultural and ethnic factors: Some Culturally and Linguistically Diverse (CALD) groups experience food insecurity due to a departure from their traditional diets when relocating to Australia. They may struggle to adapt to the local food environment and fail to adopt nutritious alternatives.
- Indigenous vulnerability: Aboriginal and Torres Strait Islander peoples are vulnerable to food insecurity due to various factors, including low income, household infrastructure and overcrowding, and limited access to transport, storage, and cooking facilities.
- Recent migration: Newly arrived migrants may lack knowledge about the nutritional value of food available in Australia, which can differ significantly from their familiar diets.
These factors highlight the complexity of food insecurity in Australia, which requires interventions at multiple levels, including individual, interpersonal, organisational, and public policy levels.

Malnutrition in older Australians
Malnutrition is a significant public health issue in Australia, particularly for older Australians. Research shows that around 50% of older Australians in aged care or the community are either at risk of malnutrition or are malnourished. This issue is often overlooked, but it can have a substantial impact on the health, well-being, and quality of life of older individuals.
Several factors contribute to the high prevalence of malnutrition among older Australians. One key factor is a loss of appetite, which can be caused by various physical and psychological issues. For example, older adults are more likely to suffer from chronic diseases such as kidney and liver disease or congestive heart failure, all of which can affect their appetite. Additionally, mental health issues such as depression, loneliness, and grief are common among older adults and can lead to reduced appetite and, subsequently, malnutrition.
Certain medications can also impair the absorption of nutrients, including vitamin B12, sodium, and magnesium. Older adults are also more likely to experience dental problems, psychological distress, dementia, social isolation, and financial difficulties, all of which can make it harder for them to access or consume nutritious food. As a result, older Australians may not be meeting their daily nutritional requirements, particularly in terms of protein and energy intake.
The signs of malnutrition in older people are often mistaken for the normal ageing process. These can include hair loss, weakness, confusion, and wounds that don't heal. Older individuals who are malnourished may also experience a decline in cognitive function and behaviour changes. They are also at a higher risk of falls, infections, and pressure wounds, and may take longer to recover from illnesses or injuries.
To address this issue, health professionals and aged care facilities should conduct regular malnutrition screening using appropriate tools. Early detection is crucial, as it can prevent the need for major treatments. Accredited Practising Dietitians (APDs) can offer practical and personalised dietary advice to help older Australians meet their nutritional needs and improve their health. Eating a variety of foods is essential, and certain situations may require specific advice, such as addressing food insecurity or managing illnesses that increase nutritional needs.

Undernourishment defined by calories
Undernourishment is a deficiency in overall calories or specific nutrients that the body requires. It is defined as the habitual food consumption being insufficient to provide the dietary energy levels required to maintain a normal, active, and healthy life. This definition is distinct from malnutrition, which is defined as a mismatch between required and consumed nutrients. Undernourishment is solely determined by the sufficiency of energy (calorie) intake and does not consider the quality or diversity of someone's diet. It is calculated using three factors: the average availability of calories across the population, the levels of inequalities in food consumption within a population (Coefficient of Variation of energy intake), and demographic information such as age structure, sex, height, and activity levels.
In developed countries, undernourishment often occurs due to the overconsumption of fast food, which is high in calories but low in nutritional value. This can lead to macronutrient overnutrition with micronutrient undernutrition. Macronutrient undernutrition, or protein-energy undernutrition, is a deficiency in proteins, carbohydrates, and fats, which are essential for the body to produce energy. Micronutrients, such as vitamins and minerals, are also crucial, despite being required in smaller amounts.
The prevalence of undernourishment in Australia was reported to be 2.5% in 2022 by the World Bank, which is comparable to rates in other developed countries. However, it is important to note that these rates may not include individuals who are overweight and undernourished due to a deficiency in specific nutrients rather than overall calories.
The fight against undernourishment focuses on sufficient energy intake, ensuring enough calories per person per day. However, it is important to remember that a healthy diet also requires adequate protein, fats, and micronutrients. Undernourishment in mothers and children is a leading risk factor for death and other adverse health outcomes, emphasizing the critical nature of this issue.
