On the prevention side, a leading health official warns people to check their sunscreen is still effective.
Cancer Society manager Fiona Mawley says using expired or heat-damaged sunscreen could be worse than using none as it could lead to people exposing themselves to harmful sun while believing they are protected.
"Most sunscreens have a three-year shelf life," she says.
"The expiration date gives a fairly definitive timeline for retailers and consumers."
Ms Mawley says keeping sunscreen away from heat is the key to preserving its effectiveness.
"The effectiveness of the sunscreen will depend on where it has been stored. It is best to store it below 30C - not in a car or golf bag," she says.
"In some cases, the formula could change appearance or split. If that happens then it should be discarded."
Wearing sunscreen is one of the best ways to help protect exposed skin from sun damage, which can cause skin cancer, including melanoma.
