New sun exposure and protection guideline

The new guideline aims to update advice about sun exposure and protection for Australia’s diverse population. The guideline was published in February 2024 and endorsed by leading experts in skin cancer including the Cancer Council. The guideline aims to balance the harms and benefits of sun exposure. The main risk of sun exposure is skin cancer, while the main benefit is that it allows your body to make vitamin D, which has many important functions including bone health.

The guideline divides Australians into three groups based on their risk of skin cancer. Those at higher risk of skin cancer need to be more cautious about sun exposure than others.

High risk

• Very pale skin that burns easily and tans minimally
• Prior history of skin cancer
• Family history of melanoma and/or
• Taking immunosuppressant medication.

High risk people should avoid sun exposure where the UV index is >3, as well as applying sunscreen daily, and adequate coverage with clothing including hats and sunglasses. Shade should be sought wherever possible. Vitamin D requirements should be discussed with your doctor.

Intermediate risk

• Darker white, olive or light brown skin that burns minimally and tans to light or moderate brown.

These people should apply sunscreen as part of their daily routine where the UV index is >3, and use sun protection as above if they will be outdoors for longer than needed to maintain vitamin D levels (about 10-20 minutes in Sydney during summer).

Low risk

• Dark brown or black skin.

The guideline does not recommend routine sunscreen application for this group. These people may need sun protection if outdoors for >2 hours where the UV index is >3.
