The strategy identifies areas at risk of coastal hazards, including sea level rise, storm tide inundation, flooding and erosion.
It outlines ways to manage risks, ranging from where buried seawalls could be built to enhancing dune protections and offering training and education about coastal hazards.
During the special meeting held on Monday to adopt the strategy, Division 9 councillor Jason O'Pray pointed to the significant erosion at Maroochydore Beach to Alexandra Headland in 2011 as an example of why coastal hazards must be managed.
"For those who can cast our minds back to 2011 when there was no sand between Alexandra Headland and Maroochydore, it was devastating, it was a tourism and economic disaster," he said.
