Sydney Harbor Turns Bright Green Due to Non-Toxic Dye Spill

Authorities confirm the green hue in the water was caused by a common plumbing dye and poses no threat to marine life.

Fire and Rescue NSW identified the green color in Sydney Harbor as fluorescein, a dye used by plumbers to detect leaks.
The dye entered the harbor through a storm drain in Kirribilli, though the exact entry point remains unknown.
Officials confirmed the dye is non-toxic and has not caused any harm to fish or other marine wildlife.
Local residents reported seeing a large amount of green liquid in the stormwater drain before the harbor changed color.
The green water was flushed out and diluted by the evening, with additional rain helping to clear the discoloration.
