The massive amounts of floodwater entering Moreton Bay in Queensland has caused thousands of fish to die.
All beaches on the Redcliffe Peninsula have been shut due to dead fish and debris washing ashore.
Local councillor James Houghten says council is working hard to clear the beaches of rubbish.
“We’ve had several thousand fish wash on the beaches and some of those have been even freshwater fish, so that looks like they’ve come from Somerset or Wivenhoe Dam even further up the river,” he said.
“We’ve already had the result of some testing back and the result is that that’s been caused by so much freshwater in dealing with saltwater varieties and also turbidity in the water.”
