Situated on Middle Island of Australia, Lake Hillier spans 600m by 250m
Navigator and cartographer Matthew Flinders had first discovered Lake Hillier in 1802
Remarkably, Lake Hillier is 8 times saltier than the ocean and thus in the 19th century it was used for salt extraction, but now it is a hub for tourism and research
Separated by a thin strip of Melaleuca-covered earth, Lake Hillier's pink water contrasts with the blue ocean
The lake is home to microorganisms like Dunaliella salina, red algae, and halophilic bacteria
Scientists speculate that Dunaliella salina microalgae or halophilic bacteria contribute to Lake Hillier's pink colour
Despite its vibrant color, Lake Hillier's water poses no harm to humans, yet swimming in Lake Hillier is prohibited
