Designing inclusive health materials for low-literacy communities in Australia

Health information often fails the people who need it most. Pamphlets, posters, websites, and discharge instructions that rely on dense text, medical jargon, or assumptions about prior knowledge leave behind large portions of the population, including older adults, people with limited English, and those who left school early. In Australia, where more than seven million adults read below the minimum proficiency needed for everyday tasks, the design of health resources shapes whether someone with type 2 diabetes takes insulin safely, whether a carer recognises stroke warning signs, and whether a remote community acts on preventive screening advice.

The 2023 APEC Conference on Promoting Community-based Non-Communicable Diseases Integrated Care Model placed these questions at the centre of chronic disease strategy. Speakers from across the Asia-Pacific shared tools for co-design, plain language, and visual communication that work in clinics, pharmacies, and community halls. The lessons apply directly to Australia, where the National Preventive Health Strategy and the Closing the Gap framework call for resources that reflect the lived realities of diverse communities, from the outer suburbs of Melbourne to the Torres Strait.

Understanding health literacy in Australian communities

Health literacy is more than reading ability. It includes the confidence to ask questions, the skills to interpret charts and medication labels, and the cultural safety to trust that information is meant for you. Data from the Australian Bureau of Statistics shows nearly 60 percent of adults score below the desired level on the Health Literacy Questionnaire, and the burden falls hardest on people with low income, those born overseas, and Aboriginal and Torres Strait Islander peoples. In Fairfield in south-western Sydney, where more than half of residents speak a language other than English at home, a single-page flyer with clinical terms can render an entire campaign invisible.

Effective materials start with empathy and local knowledge. Designers benefit from spending time in places where people actually receive care: community health centres in Logan, Aboriginal Medical Services in Alice Springs, and Diabetes Australia offices in Adelaide. Listening to reception staff, pharmacists, and peer support workers reveals which words confuse patients, which diagrams are misread, and which instructions are quietly ignored. Without that groundwork, even well-intentioned brochures can reinforce stigma or fail to change behaviour.

Plain language and visual design principles

Plain language is not about simplifying ideas; it is about removing the barriers that hide them. The Australian Government Style Manual recommends writing at a year-eight reading level for general public communication, yet much of the health material circulating in hospital foyers still reads like a journal abstract. Short sentences, common words, and direct address help. "Take one tablet with breakfast" is clearer than "Administer a single oral dose of the medication in the morning with food." Active voice, second person, and consistent terminology across a campaign reduce cognitive load, especially for people juggling multiple chronic conditions.

Visual design carries equal weight. High contrast between text and background, generous white space, and sans-serif fonts at a minimum of twelve points improve readability for older readers. Icons can be powerful, but only if they are tested with the target audience. A pictogram for "take with water" should not look like a shower, and a heart symbol should not be confused with the icon used for a like button on social media. Colour choices matter too: red and green together can be inaccessible to people with deuteranopia, and culturally specific colours carry different meanings across communities. The Mindframe guidelines from the Hunter Institute offer practical guidance on imagery and tone for sensitive topics such as suicide prevention and alcohol harm.

Cultural safety and linguistic diversity

Australia is one of the most multilingual societies in the world, and health materials must reflect that reality. Translating an English leaflet into Mandarin or Vietnamese is rarely enough on its own. Concepts such as informed consent, advance care planning, or the difference between type 1 and type 2 diabetes do not always map neatly across cultures. Community-led adaptation, working with bicultural workers and accredited interpreters, ensures that meaning survives the journey between languages. The Victorian Health and Human Services Language Services Standard provides a benchmark for this work, and similar frameworks exist in New South Wales and Queensland.

For Aboriginal and Torres Strait Islander communities, cultural safety goes beyond translation. It involves recognising the role of family and community in decision-making, respecting traditional healing practices, and ensuring that images and narratives reflect local identities rather than pan-Indigenous stereotypes. Resources co-designed with organisations such as the Aboriginal Health and Medical Research Council of NSW or the Western Australian Aboriginal Health Strategy have shown how visual storytelling, yarning circles, and locally relevant metaphors can make preventive health messages land. When a campaign about cardiovascular risk uses familiar foods, local landmarks, and respected community voices, it moves from being read to being trusted.

Testing materials with the people who use them

Co-design is not a single workshop; it is a cycle of testing, listening, and revising. Before a brochure about kidney disease is printed for distribution in Perth or Hobart, it should be read aloud by people who match the target audience. Ask them to circle words they do not understand, to explain the instructions in their own words, and to point out images that confuse or offend. This kind of usability testing catches problems that no amount of internal review will find. The NSW Clinical Excellence Commission has published checklists for consumer feedback, and many Primary Health Networks now embed this practice into their project cycles.

Numbers deserve special attention. Many adults struggle with concepts like "one in four" or "30 percent risk." Visual representations, such as icon arrays showing 100 figures with 25 highlighted, communicate risk far more effectively than percentages. Similarly, dosing instructions should be tested for clarity. "Take two tablets twice a day" is different from "take two tablets in the morning and two at night," and the difference matters for safety. Where possible, numeric information should be paired with practical comparisons: a portion of rice the size of a tennis ball, a serve of meat the size of a deck of cards. These everyday references, familiar from the Australian Guide to Healthy Eating, anchor advice in daily life.

Digital accessibility and trustworthy online resources

Health information is increasingly digital, and low literacy is not the same as low digital access. Many older Australians use smartphones to search for symptoms, book appointments, and check My Health Record. A website that loads slowly, uses tiny text, or relies on video without captions excludes them immediately. The Web Content Accessibility Guidelines offer a clear technical baseline: descriptive alt text, keyboard navigation, captions for multimedia, and sufficient colour contrast. The Australian Government Digital Service Standard requires agencies to meet these benchmarks, and the private sector is catching up.

Equally important is helping people judge whether online health content is reliable. Health misinformation spreads through many of the same channels as other deceptive online content, and the evaluation skills are transferable. Frameworks developed to help consumers assess the trustworthiness of digital platforms, including the structured criteria discussed in online reliability assessments, offer useful lessons for health communicators designing consumer guidance. Domains ending in .gov.au, .org.au for established charities, and major hospital sites are generally safer starting points than sponsored social media posts. Healthdirect Australia provides a trusted gateway, and the Therapeutic Goods Administration maintains a searchable database of approved medicines and devices. When in doubt, readers should be encouraged to ask their GP or pharmacist, and health materials should make that step visible and welcoming.

Supporting chronic disease self-management at home

Most of the work of managing diabetes, hypertension, or heart failure happens between clinic visits, often in kitchens, living rooms, and bedrooms. Written instructions are only part of the picture. Teach-back, where a clinician asks the patient to explain their care plan in their own words, is one of the most effective tools for confirming understanding. Visual aids, such as colour-coded pill boxes, large-print calendars, and fridge magnets with blood pressure targets, support daily routines. For people with vision impairment, audio recordings and tactile labels can fill gaps that print cannot.

Programs that pair clinical care with community navigation show how design and service delivery reinforce each other. The patient navigation frameworks discussed at the APEC conference highlight the role of peer workers in bridging language, cultural, and literacy gaps. In Australia, similar models operate through organisations such as Diabetes Queensland and Heart Foundation Walking groups, which combine printed resources with face-to-face support. When materials are part of a relationship rather than a transaction, they become tools of empowerment rather than artifacts of compliance.

Aligning with policy and building sustainable resources

Inclusive design is most effective when it is backed by supportive policy. The National Health Literacy Strategy under development by the Australian Commission on Safety and Quality in Health Care, the renewed focus on consumer engagement under the Primary Health Networks, and the cultural safety frameworks within the National Agreement on Closing the Gap all create demand for better materials. Funders, including the Department of Health and Aged Care and state health departments, increasingly require evidence of co-design and evaluation in grant applications. This shift makes inclusive design not just an ethical choice but a funding requirement.

Long-term sustainability depends on shared infrastructure. Open-licence image banks, plain-language glossaries, and reusable templates reduce duplication across the sector. Partnerships with peak bodies, universities, and international networks help maintain quality and keep pace with evidence. The 2023 APEC conference highlighted how cross-border collaboration, drawing on experience from countries with similar challenges, can strengthen local practice. Speakers noted the value of aligning with global initiatives on medication safety, including cold chain standards supported by international health partners, which inform Australian adaptations for storing insulin and other temperature-sensitive treatments. By pooling effort, the sector can ensure that every new health resource is more inclusive than the last.

The conference resource portal offers downloadable templates, case studies, and evaluation tools for teams ready to put these ideas into practice. Health professionals, community workers, and policy makers across Sydney, Melbourne, regional centres, and remote communities can access session recordings, slide decks, and the full programme book through the official site. Review the materials, share them with your team, and start a conversation about which resources in your own service need redesign. The next patient who walks through your door deserves information that is clear, respectful, and built with them, not for them.
