Melbourne's naturally pink lake delights tourists

Tourists and locals alike have flooded to Westgate Park in Melbourne to witness one of the most Instagrammable spectacles of recent times.

The water in the park lake has turned bright pink, as if victim to an industrial paint spill. Thankfully, the phenomenon is natural – the product of sunlight, high temperatures and low rainfall.

The lake is already filled with salt water, and when dry conditions make the water saltier still, algae in the lake begins to thrive. As their numbers multiply, they release a red pigment called beta carotene, which diffuses through the water, lending it this strange hue.

Get your selfies in now: With cooler weather and increased rainfall, Parks Victoria expect the lake to soon return to its usual blue come autumn.

Although the water is not dangerous, people are being advised not to go for a dip. It may look like a mixture of candy floss, strawberry milkshake and bubblegum, but the super-high salt levels can irritate your skin.
