Preferred adaptation outcomes and associated actions for Peregian Beach
The assessment of erosion risks in Peregian Beach shows that the level of risk to some recreation
and infrastructure asset types may become intolerable by mid-late century.
Analysis of economic, social, and environmental considerations, as well as multiple legal and
governance constraints and input from the Noosa community indicates the most suitable and
feasible adaptation pathway in this locality is one that provides continuous support for natural coastal
processes and existing beach use, amenity, and adjacent recreational values by implementing natural
coastal protection solutions and a medium- to long-term transition of recreational and infrastructure
assets away from high erosion risk areas.
As a result, the preferred adaptation outcomes for this locality are:
    -	Implement measures that support and enhance dunes, beach health and natural coastal
       processes as soon as possible
    -	Prevent the construction of hard protective structures where possible that are likely to
       exacerbate erosion risk, impact on preferred outcomes for dune and beach health, impair
       natural coastal processes, and lead to adverse impacts on neighbouring areas
    -	- Re-locate important recreational and infrastructure assets outside the projected high-risk
       coastal erosion prone area by 2070
    -	Where important recreational and infrastructure assets cannot be feasibly re-located, seek to
       accommodate the risks by adapting the design of these assets to be more resilient during and
       after a major erosion event.
Figure 12 shows the expected progression of actions to support these preferred outcomes between
years 2020 and 2100. Table 5 provides a
