THIS frightening photo shows how vital it is for children to wear bright coloured swimwear as a child in a blue swimsuit is near impossible to spot.
At first glance, the photo appears to show an empty outdoor swimming pool.
But the slightly darker patch circled above in a child wearing pale blue shorts swimming at the bottom of the pool which was also murky from sunscreen.
The Australian Facebook group CPR Kids, which is run by registered nurses, shared the photo and issued a stark warning to parents to ensure their child could be visible with brightly coloured costumes.
