SLOWING the rapidly growing sandbar off the Urangan Pier will be one of the most "significant" projects the council has ever undertaken, Trevor McDonald has declared.
For several hundred metres, an increasing sandbar named the Dayman Spit runs from Dayman Point to the end of the Urangan Pier before swinging left.
Speed of the sand building is not known, but a bold plan to use it for good has been hatched.
Trevor McDonald, the Fraser Coast Regional Council's infrastructure councillor said the forming sand could be used to replenish the disintegrating beaches of Hervey Bay.
With the Dayman Spit lying in the Great Sandy National Park and Fraser Island's world-renowned biosphere, the council face a complex process of moving the sand.
Cr McDonald said the council would need to finalise a dredging design and then submit an application to the State Government before the marine park boundaries and zoning was reviewed later this year.
"It's always been a fish habitat and more recently a marine park," he said.
The retiring councillor said the council had engaged consultants to work on designing a plan to dredge the sand from the spit and use it on the Bay's beaches.
He said the spit could not be allowed to grow and completely remove water from underneath the pier on a low tide.
"The problem is getting worse every year - it's trapping more and more sand," he said.
"We've simply got to do it - it's necessary to make the beach more pleasant for people."
Expected to cost millions of dollars, Cr McDonald said the dredging would be an ongoing process and it needed to be done properly.
"We have ten years worth of data (on the sandbar)," he said.
A spokesman from the Queensland Government said dredging sand from the Dayman Spit would require approval from the Queensland Parks and Wildlife Service and Environment and Heritage Protection.
"Dayman Spit is within a conservation park zone of the Great Sandy Marine Park and is considered a highly protected area where limited extraction only is permitted by the zoning plan," he said.
"On the basis of the requirements of the zoning plan, any significant dredging would not be approved."
The spokesman would not make comment about who would pay for the dredging.
"Funding for this type of dredging project is not a matter for QPWS or EHP."
