Are Aussie waters safe? Sighting at one waterfront restaurant leaves families appalled

Australians cherish their beautiful coastlines and pristine shores.

However, a recent sighting at a popular family spot in Noosa left locals and visitors alike in a state of shock and disgust.


Diners at the Noosa Boathouse, a waterfront restaurant, were confronted with a sight far from the usual sparkling blue waters they were accustomed to.

Diners saw a bizarre grey substance coating the surface of the Noosa River, a spot known for its recreational appeal where 'all the kids swim'.

A resident posted photos and a video of the grey and white substance swirling on the water's surface, which resembled sewage.

The footage also captured a group of ducks navigating through the muck, described as 'putrid' and 'disgusting'.

The unsettling sight raised concerns about water pollution and the health of the river's ecosystem, as fish were not visible in the area.

Some residents wondered if it was coral spawn, while others suggested it could be sewage.


University of New South Wales' water expert, Dr Ian Wright, explained the strange phenomenon.

'My immediate thought was algae,' Dr Wright shared.

'They come in so many different sizes, shapes and colours and, in combination, can look like paint in the water. It is thought that the coloured secretions offer a kind of sunscreen protection.'

The Noosa Boathouse's management reassured the public that the occurrence was a natural event.

'This happens when there is a north-easterly and an incoming tide as we had last night,' the restaurant management stated.

'Especially after some rain, things in the river get stirred up, including algae and coral spawn. With the tide and wind we've had, it gets blown into the catchment area between the Boathouse and the pontoon.'


The Boathouse also stated that they regularly clean up foreign debris that gets blown into the area between the restaurant and the pontoon.

The restaurant assured community members that the fish and aquatic life were still present and there was nothing to worry about.

While the Noosa Shire Council had not responded to the incident, Noosa Boathouse's explanation has alleviated some of the community's concerns.

It's important to understand the environmental processes that sometimes lead to alarming yet harmless occurrences.

We encourage everyone to stay informed about their local environments and to report any unusual sightings to the authorities.

It's through vigilance and collective efforts that everyone can enjoy nature, including waterways.
