        Table 7 - Change in Teewah and Noosa North Shore asset erosion risk profiles across planning horizons


At present, the only methods for mitigating the risks at Teewah and along Teewah Beach are:

    -   Existing 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 of erosion and accretion.


Adaptation outcomes and associated actions – Erosion

The assessment of erosion risks in along the open beaches of Noosa North Shore and at the
Teewah township show the level of risk to most assets is acceptable for much of the planning
period. However, there are likely to be intolerable risks to the camp ground and Teewah road
access by mid-century, as well as to private houses by 2100.

Analysis of economic, social, and environmental considerations, as well as input from the Noosa
community indicates the most suitable adaptation pathway in this locality for responding to coastal
erosion is one that supports natural coastal processes and existing beach use and amenity values
by implementing natural coastal protection solutions and transitioning public recreational and
infrastructure away from high erosion risk areas over the medium term.

As a result, the preferred adaptation outcomes in response to these erosion risks 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
    -   Avoid risks to camp ground infrastructure by relocating these out of the high-risk area by
        mid-century
    -   Avoid further development in high-risk beach erosion areas in order to mitigate the risks to
        people, property and the environment.

15 The infrastructure of concern is the use of the beach as the Esplanade and the primary access method for

the Teewah township, thus representing an accessibility risk for the community.
