5       Proposed Implementation Pathway
5.1     Introduction
        A proposed strategy for managing erosion at Dog Beach and avoiding a breakthrough of The Spit is
        provided below, building on the understanding of the system presented in the previous Chapters.

        A trigger-based approach for coastal management was introduced in Section 4.2 and has been used
        to develop the strategy. Here the approach is embedded within the ‘risk continuum’ framework
        originally described by Fisk and Kay (2010). This approach was established to deal with uncertainty
        associated with climate change adaptation and planning. However, it has also been readily accepted
        and integrated into leading practice within the context of contemporary coastal management in
        Queensland (see Barnes et al., 2017). The risk continuum acknowledges uncertainty in the success
        of management actions and relies on ongoing monitoring and performance criteria to trigger changes
        in approach to achieve an overarching objective.

        The risk continuum is illustrated in Figure 5-1. Within this approach, it is important to define the point
        of unacceptable impact, i.e. the point at which the relevant planning outcome has failed or can no
        longer be achieved. Working back from this point allows identification of one or more triggers for
        enhanced management action and implementation to avoid reaching the unacceptable impact.
