The natural phenomenon can occur any time of the year but is most common during spring and summer, when the water is warmer.
To trigger the display, the water needs to be agitated - either from a strong current or wave.
Other occurrences of Bioluminescence have been observed Sydney's Lavender Bay in 2021, Tasmania in 2021 and 2023 and Jervis Bay in NSW in 2020.
