Hutt Lagoon

Hutt Lagoon is near Port Gregory, which is just north of Geraldton in Western Australia. The lagoon is a bright pink colour due to a bacteria that becomes lodged in the salt grains. The bacteria is a source of beta carotene which is extracted from the salt.
Several years ago I walked past a couple of sailors in the Royal Botanical Gardens. The must have been at sea for a while but when I walked past them they were discussing the colour of the water in Sydney Harbour. After travelling around Australia and New Zealand recently I can now understand their fascination with the colour of water from different destinations. Have a look at my slide show “Cool Waters” to get a better idea.
