Campers and residents in low-lying coastal areas of south-east Queensland are being urged to prepare for inundation from the highest tides of the year.
Emergency Management Queensland (EMQ) says the abnormally high tides will affect the coast between Fraser Island and the Gold Coast from today.
The peak is expected on Saturday morning and EMQ regional director Mike Shapland says people living and holidaying in coastal areas, particularly caravan parks, should be on alert.
"Sandbagging, moving vehicles and moveable items out of the areas that may well flood but if you're camping there you may well be taken unawares," he said.
"Luckily these tides will be occurring in daytime, so people living or indeed camping near the beach over this weekend should really look out for their own safety."
The high tides are combining with a low off the coast and Mr Shapland says big surf could also cause strong currents and beach erosion.
The highest tides will occur between 8:00am (AEST) and 1:00pm each day.
