A quick walk at lunch, a Saturday at junior sport, a shift on a building site or an afternoon in the garden can add up to significant ultraviolet (UV) exposure. In Australia, melanoma prevention habits need to fit real life, not just beach days. Consistent sun protection and timely skin checks are practical actions that can reduce avoidable UV damage and help find suspicious changes early.
Melanoma is one of the most serious forms of skin cancer because it can spread to other parts of the body. Yet it is often highly treatable when detected early. Knowledge can save your life, particularly in a country with some of the highest melanoma rates in the world.
Melanoma prevention habits start before you feel hot
Sunburn is a clear sign of skin damage, but it is not the only concern. UV radiation can damage skin on cool, cloudy or windy days, when people are less likely to feel the heat and more likely to skip protection. You cannot see or feel UV radiation, and a tan is not proof that your skin has adapted safely. It is a response to damage.
Make checking the UV Index part of your morning routine, alongside checking the weather. When the UV Index is 3 or above, use sun protection. In many parts of Australia, that threshold is reached for much of the year, not only in summer.
This matters for everyone, but the stakes are higher for people with fair skin, a history of sunburn, many moles, a personal or family history of melanoma, or regular occupational sun exposure. People with darker skin can also develop melanoma and other skin cancers. Their risk may be lower overall, but delayed diagnosis can lead to worse outcomes. No one should dismiss a changing spot because of their skin colour or age.
Build protection into ordinary routines
The most effective approach is not relying on one product or one perfect behaviour. It is layering protection so that if one measure falls short, another still reduces exposure.
Dress for UV, not just the temperature
Covering skin is one of the most reliable forms of protection. Choose a long-sleeved shirt with a close weave or UPF rating when you will be outside for extended periods. A collar can help protect the neck, an area that is easily missed, particularly for people who work outdoors or spend hours driving.
A broad-brimmed, bucket or legionnaire-style hat gives better protection for the ears, neck and face than a baseball cap. Add close-fitting wrap-around sunglasses that meet Australian standards to protect the delicate skin around the eyes as well as your vision.
This does not mean you must wear heavy clothing through every hot day. It means planning for the conditions. Lightweight, breathable fabrics and purpose-designed workwear can make coverage more manageable. For tradies, delivery drivers, farmers and outdoor sport participants, protective clothing should be standard equipment, not an optional extra kept for extreme heat.
Use sunscreen properly, but do not rely on it alone
Choose broad-spectrum, water-resistant SPF 50+ sunscreen. Broad-spectrum matters because it protects against both UVA and UVB radiation. Apply it generously to clean, dry skin about 20 minutes before going outdoors, including the ears, back of the neck, scalp where hair is thinning, hands, feet and lips where appropriate.
Reapply every two hours when outdoors, and sooner after swimming, sweating or towel drying. A single rushed application in the morning is rarely enough for a full day outside. Keep sunscreen where you will actually use it: near the front door, in your work bag, in the ute, or with sporting gear. Check the expiry date and avoid leaving it in excessive heat for long periods.
Sunscreen is valuable, but it is not permission to stay in direct sun longer. Shade, clothing, hats and sunglasses remain essential. The best balance depends on the activity. A parent at the park may be able to choose a shaded spot; a roofer may need scheduled shade breaks and protective workwear. The goal is reducing cumulative exposure in ways that are realistic enough to repeat.
Plan the day around UV exposure
When practical, schedule outdoor tasks outside the middle of the day, when UV levels are often strongest. Seek shade under verandahs, trees, shelters or portable canopies, but remember that reflected UV from water, sand, concrete and pale surfaces can still reach your skin.
At work, prevention should not depend solely on individual willpower. Employers can support safer habits through shade structures, protective uniforms, accessible sunscreen, UV-aware rostering and regular reminders. If your job keeps you outdoors, speak up about sun safety. Skin cancer prevention is a workplace health issue, not a cosmetic concern.
Prevention includes noticing what changes
Even excellent habits cannot erase every past exposure or prevent every melanoma. That is why prevention and early detection belong together. Get familiar with your own skin so you can recognise what is new, changing or simply not healing.
Check your skin about once a month in good light. Use a mirror for hard-to-see areas or ask someone you trust to check your scalp, back and the backs of your legs. Look beyond the places that catch the most sun. Melanoma can occur on the soles of the feet, under nails, between toes, on the scalp and in other less obvious areas.
The ABCDE guide can help identify concerning pigmented spots: asymmetry, an irregular border, varied colour, a diameter that is growing, and evolution or any change over time. But do not wait for a spot to match every part of that guide. Some melanomas are small, pink, red, skin-coloured or without obvious pigment.
Pay attention to the “ugly duckling” sign: a lesion that looks noticeably different from your other moles. Also arrange medical review for a sore that does not heal, a spot that bleeds or crusts without a clear reason, a new or changing dark streak under a nail, or a mole that becomes itchy, tender or raised.
When to book a skin check
Do not try to diagnose melanoma from a photo, an online checklist or a friend’s opinion. If you notice a suspicious change, book an appointment with a GP or qualified skin cancer clinician promptly. Every minute counts when a potentially serious lesion is being assessed.
A clinician may examine the area with a dermatoscope, ask about your history and decide whether monitoring, photography, referral or biopsy is appropriate. A skin check is not a guarantee that you will never develop skin cancer, and not everyone needs the same screening schedule. Your ideal plan depends on your risk factors, skin type, past sun exposure and whether you have previously had skin cancer.
People with a personal history of melanoma, a strong family history, numerous atypical moles, immune suppression or substantial occupational sun exposure may need more regular professional checks. Ask your clinician what follow-up schedule is right for you. If you have a changing lesion, do not wait for your next routine appointment.
Make the safer choice the easy choice
Lasting melanoma prevention habits are usually built through small environmental changes, not good intentions alone. Put a hat beside your keys. Keep SPF 50+ sunscreen in places you leave from. Choose the shaded side of the oval. Add a monthly skin check reminder to your mobile. Teach children that sun protection is as routine as a seatbelt, while remembering that adults need the same consistency.
Past sun exposure cannot be changed, but your next decision can. Protect your skin whenever UV levels call for it, and treat a new or changing spot as a reason to seek clinical advice without delay. A timely skin check can provide reassurance, or it can lead to the early treatment that saves your life.
