Aussies fear the worst after waters in Sydney mysteriously turn deep red

A Sydney harbour became reminiscent of a horror movie when seawater turned blood red, leaving locals shocked and alarmed.

Milson Park in Kirribillli, Sydney, found itself at the centre of the strange scene this week as residents of the wealthy Australian suburb noticed the scarlet stream that began to gather around the harbour.

Puzzled residents had no idea what had caused the unexpected change in colour, with the local council sending officials to the area to investigate.

But even the authorities were unable to work out what had caused the mysterious change in colour – with just one theory put forward.

Officials suspect that the strange occurence was not caused by a murder, or anything sinister at all, but by some oblivious plumbers.

Investigators traced the flowing blood red water back to a drain, leading them to believe that a plumbers’ dye called Fluorescein had caused the dramatic change to the waters

North Sydney Council alerted the North South Wales Protection Authority, who are also investigating the source of the problem.

In a statement, the authority said: ‘North Sydney Council alerted us to what appears to be red plumbers’ dye in a drain at Kirribilli this afternoon and we are currently investigating the potential source.

‘Fluorescein has low toxicity but even small amounts can be highly visual and for this reason its use should always be minimalised.’

That’s not the only time a blunder by an Aussie plumber has caused such issues though.

Just a couple of months ago, residents in North Sydney were left stunned when water near their homes turned fluorescent green.

Concerned locals called firefighters who, again, traced the cause of the water back to a drain.

And yes, you guessed it, the root of the problem was plumbers’ dye.

No hazards to marine life or surrounding properties has been identified.
