It was concluded that'
          A -do nothing" approach was unlikely to be a viable long-term solution
          The lowest-risk strategies involved stabilizing the present channel location
     •    If protection of the Noosa River Spit was important, extension of the rock wall along critical sections was
          recommended
     •    If protection was considered less critical, relocation of the channel should be considered.

Advice from EPA recommended further investigation into Options B [establishing erosion control lines] & D [relocating the
channel]. Further investigation into relocating the channel was not feasible in 2006 due to the extent of the erosion along
critical areas of shoreline, the uncertainty relating to this strategy and the time it would take to implement. Noosa Shire
Council decided to proceed with Option B. As erosion along critical sections had already breached erosion control lines, a
rock wall was constructed. Further erosion adjacent to this area in subsequent years resulted in further breaching of the
erosion control lines and the rock wall was extended in 2008 [Figure 5].

2.   EXISTING SITUATION

Over recent years, the Noosa River Spit has been the subject of serious ongoing erosion [Figure 6]. This has resulted in the
loss of public access paths [Figure 7], what was a popular protected public sandy beach area known as "dog beach" [Figure
8] as well as established vegetation [Figure 9].
