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."
