South East Queenslanders have been urged to be cautious if they plan to head to the beach this weekend, due to concerns recent flooding has impacted water quality.

Runoff from the Nerang River, Tallebudgera Creek, and nearby farmland into the ocean is likely to have increased the amount of bacteria present in the water.

Griffith University Environmental Health expert Anne Roiko said that pollution from runoff water generally clears away roughly twenty four hours after heavy rainfall, but that people with open cuts and young children should reconsider entering the water this weekend.
