Excessive exposure to UV radiation will burn the skin and can lead to skin cancer.
Parents who repeatedly don't apply sunscreen on their children in the hot summer sun have been accused of child abuse by a top doctor.
Australian Medical Association NSW President Dr Brad Frankum said not applying sunscreen to your child could have deadly consequences, and has put parents on notice asthe weather in both Australia and New Zealand reaches new highs.
"Is it negligence? If a child burns themselves by tipping boiling water over themselves… I don't see severe sunburn is any different," Prof Frankum told the Daily Telegraph.
"If it happens repeatedly then that would be quite abusive really. It's no different to burning your kid with something else."
However, Surgeon Fina Wood told the Daily Telegraph that the majority of parents caught out were guilty of "forgetfulness" rather than "intentional neglect".
She warned parents are getting caught out, believing that "putting your baby under a tree thinking your baby is in the shade is not adequate."

Under New Zealand's extreme UV levels, all it takes is 10 minutes to get burnt.
Prof Frankum warned parents who believed getting a tan was good for their child's skin needed to be re-educated about the dangers of the sun and skin damage.
