Beachgoers in Tasmania have been sharing incredible images of a bioluminescence event at Preservation Bay on the state's north-west coast. The bright blue glow is caused by billions of single-celled algae or plant plankton called Noctiluca scintillans, and more commonly known as sea sparkle.
When disturbed by waves or currents, the tiny cells flash causing an illumination in the water around them.
