This phenomenon is uncommon and caused by a bioluminescent alga called noctiluca scintillan, or popularly known as "sea sparkle" when the organisms are feeling stressed.
Tasmania's virgin forests and free-roaming wildlife and ecosystems could be disrupted by modern and densely populated tourism in the near future -- reasons to see the untouched beauty of the natural spectacle as soon as possible.
