Australia’s pink lakes - Tourism Australia.
Lake Hillier is one of Australia’s most famous pink lakes, located off the southern coast of Western Australia on Middle Island. British explorer, Matthew Flinders, discovered the lake in January 1802 when he climbed the highest peak on the island and noticed “a small lake of a rose colour”.
The lake — near the city's Westgate Bridge — started to turn pink last week and is expected to stay like that until later in autumn when it will return to being blue as the weather cools down.
A pink lake is a lake that has a reddish or pink colour due to the presence of algae that produces carotenoids (organic pigments), such as Dunaliella salina - a type of halophile green micro-algae especially found in sea salt fields. Because of pink color, these lakes are becoming increasingly popular among tourists and photographers from around the world.
Pink lakes are very rare natural wonders. There are only a few known pink lakes in the world. They all are salty and mesmerizing. Lake Retba or Lac Rose is an unusual spot in Senegal. Its water has pink color due to the Dunaliella salina algae found in it. However, it does not cause any harm for swimmers.
The Pink Lake is a documentary film that investigates the facts of the pink lake in Senegal and the people who work in the lake in the extraction of salt and other related jobs. This unique lake is an important source of livelihood for the people around it where they depend on the extraction of salt, to flourish trade, tourism; arts, social relations, love, marriage, and the myths that appear.
Esperance’s Pink Lake has lost its pink colour due to a number of contributing factors. With the construction of the railway line and South Coast Highway, Lake Warden and the eastern lakes no longer flush into Pink Lake during heavy rains, this flushing brought in accumulated salts from other lakes into Pink Lake.
