Noosa is being forced to reckon with the impact of rising sea levels, as council research shows two beaches immediately to its south will deteriorate from the effects of erosion by 2040.
Sunshine, Sunrise and Perigian beaches are all at risk, with the rising water levels and erosion affecting not only the landscape, but also the luxury homes perched just onshore.
Draft plans to manage the erosion risk float a range of options, including cycles of pumping additional sand to the beach, earthmoving and revegetating the area.
Council acquisition of private properties is off the cards, deemed not to provide a large enough benefit for its cost, while implementing development controls is also considered insufficient to fully curb the effects of erosion.
