At present, the only methods for mitigating the risks in Sunrise Beach and Sunshine Beach are:

    -   Maintaining and enhancing vegetated dune areas, which act as a natural buffer to erosion
        by dispersing wave energy during storm events
    -   Planning controls on coastal development that prevent encroachment into the vegetated
        dune areas, thereby preserving natural coastal processes.


Adaptation outcomes and associated actions

The assessment of erosion risks in Sunrise Beach and Sunshine Beach show the level of risk to
residential, recreational, and natural assets could become intolerable within 20 years, with risks to
tourism and service infrastructure assets likely to remain tolerable until late century due to their
distance from the projected erosion prone areas.

Analysis of economic, social, and environmental considerations, as well as multiple legal and
governance constraints and significant input from the Noosa community indicates the most suitable
and feasible adaptation pathway in this locality is one that supports natural coastal processes and
existing beach use and amenity values by implementing natural coastal protection solutions and a
medium- to long-term transition of development and public assets away from high erosion risk
areas.




10 These results are driven by exposure of David Low Way as it crosses Burgess Creek.
11 These risk results are being driven by the high level of exposure of private assets along Arakoon and

Seaview Tce. Properties on beachfront streets south of the Sunshine Beach SLSC have a lower risk rating.
12 The recreational asset most at risk in Sunshine Beach is Ed Webb Park.
