Lovers of Bribie Island should not be concerned about long-term environmental damage as a result of several lagoons bursting over the weekend, experts say.
Campers and day-trippers witnessed first-hand the lagoons breaking their banks and creating rivers of water that flowed into the sea.
The Department of Environment, Science and Innovation said it was a common event on the island after periods of heavy rainfall.
Rangers said they were not concerned about long-term damage, although encouraged motorists to avoid driving through fast-flowing water.
“The Welsby Lagoon, Mermaid Lagoon and Norfolk Creek have broken through to the ocean following recent heavy rainfall, with Freshwater Creek also expected to break through over the coming days,” a spokesperson said.
“This is a natural process that occurs after periods of heavy rainfall.
“We are aware of community reports of people digging near Norfolk Creek, however, a washout was imminent, regardless of human interference, as water had already started to top the natural barrier.
“Members of the public are reminded not to disturb the island’s beach and coastline as this can be dangerous and these areas are protected.
“Rangers have carried out patrols of the area and have provided safety advice to visitors and motorists.
“Deep washouts are likely around all the lagoons with conditions changing on a tidal basis.
“Beach travel is recommended one hour on either side of low tide, and all motorists should use caution when travelling along the open sections of beach and travel at a reduced speed to avoid hazards.
“Visitors are reminded to always check Park Alerts for the latest information.”
The first lagoon broke its banks after heavy rain on Thursday night, cutting off campers.
Several motorists came unstuck trying to get out, although there were plenty of good Samaritans willing to tow vehicles to safety.
