Restoration Plan

 

Figure 4. Planned oyster reef restoration sites in the Noosa River estuary.

The oyster reef restoration units are open-weave coir mesh bags (30 cm diameter x 1m long) filled
with oyster shell. Coir will be sourced from commercial providers of erosion management products. All
oyster shells used will be treated in accordance with the conditions of the Beneficial Use Permit
issued by the Department of Environment and Heritage Protection on 7 November 2016
(ENBU07017216). These include:
1. Sourced from oyster processing centers and/or restaurants; and
2. Cleaned and sterilized through:
a. Using hoses or high pressure wasters to remove any soft tissue; and
b. Drying in direct sunlight at >18°C for at least 3 months
OR
c. boiled in water for a period of at least 5 minutes.

Each oyster shell filled coir bag will be constructed on land, then transferred to the site using a small

boat or barge. At each site, three clusters of bags, arranged in a 5 m equilateral triangle, will be
deployed as shown in the detailed design drawings (see appendix 5). The bags will be fixed with large
