There are concerns the ocean could be about to break through the northern tip of Bribie Island, north of Brisbane.
Big seas have eroded large sections of the ocean side of the island opposite Golden Beach.
Residents living on Pumicestone Passage have been worried about a break through for many years.
However, Sunshine Coast councillor Tim Dwyer believes the problem could fix itself.
"It might be very serious - at the moment I'm not sure," he said.
"My particular point of view, [it's] pretty hard to beat nature when it comes to the wind and the ocean - sand moves very easily.
"It's a cyclical thing, so let's rejuvenate and put some sand there to try and protect the break through point.
"If we've got to do that on a continuous, ongoing basis and it gets the result we're looking for, to me that comes out as a pretty simple solution but it could be more complicated than that."
Cr Dwyer says most beaches in south-east Queensland have been affected by erosion in recent months.
"Bribie Island's no different, so I'm not surprised that it's a topic of conversation at the moment," he said.
"What we as a local government have got to do is continue to work with the State Government - they're the authority here.
"If nothing else what we can do to move a bit of sand around to continually artificially protect that break through point by the addition of sand, which is a natural component in that environment anyway."
