1. PURPOSE & PERFORMANCE
1.1. Works are to restore rock oyster ecosystems throughout the Noosa River estuary at sites that meet site suitability criteria and
positively interact with current human uses.
1.2. Works may provide some erosion protection; however, they have not been designed specifically for this purpose.
1.3. As the works do not include geotextile underlayer, some settlement is to be expected and has been factored into the design.
1.4. Module layouts have been developed to allow water flows through the structure to reduce siltation, however some siltation is to
be expected and has been factored into the design. Module layouts are to be laid as reef patches and may be curved or shaped SITE
to reflect the local bathymetry and specific constraints of each restoration site.
1.5. Inundation and overtopping during higher tides and flood events is to be expected.
2. SCOPE OF WORKS
2.1. Phase 1. Deployment of restoration substrates in modular forms at 4 restoration sites.
2.2. Phase 2. (SUBJECT TO SEPARATE APPROVAL) Deployment of restoration substrate at additional sites and/or to augment or
maintain existing sites throughout the estuary as funding allows. Additional sites to be progressively selected from within the
NOOSA SOUND EAST SITE 2.3.
identified Restoration Zones (refer Note 5).
Works may include seeding of substrate with oyster spat and/or live oysters. Oysters to be sourced from brood stock within the
Noosa River and/or culture stock from oyster gardening within the Noosa River.
2.4. Works may be staged. Individual sites may be staged subject to engineer's certification.
2.5. Deployment of navigation buoy(s) at each site and signage in accordance with permit conditions. NOTES
NOOSA SOUND WEST SITE 2.6. Works to be undertaken in accordance with the Project Restoration Plan.
2.7. Monitoring and Maintenance, as required (refer Note 4.)
2.8. Works may need to be adapted in response to climate change, depending on monitoring of habitat health.
3. NOOSA RIVER FISH HABITAT AREA, MATTERS OF STATE ENVIRONMENTAL SIGNIFICANCE & MARINE PLANTS
3.1. The objective of the works is to restore oyster-dominated ecosystems to the Noosa River estuary including within the Noosa
River Fish Habitat Area.
3.2. Two of the Phase 1 Restoration Sites, Tewantin and Goat Island, are within the Noosa River Fish Habitat (A) Area. The Noosa
Sound East and Noosa Sound West restoration sites occur outside of the Noosa Fish Habitat Area. The Phase 2 Restoration
Sites have not been selected, but will be within the Noosa River Fish Habitat Area (except for any further works in Noosa Sound
restoration sites).
3.3. Works to occur within the identified Restoration Zones, within 30m from shore, in water depths less than 2m below MLWS. The
GOAT ISLAND SITE exception to this is the Tewantin site where works are proposed on existing rocky substrate, or in the future where otherwise
approved in writing by MSQ.
TEWANTIN SITE 3.5. Phase 1 works results in temporary impacts to sparse marine plants at Tewantin site only.
3.6. Works are NOT to impact on existing terrestrial vegetation (including vegetation within mapped MSES).
3.7. During construction, plume is to be minimised and monitored visually to ensure no impacts to adjacent marine plants. Turbidity
monitoring to be undertaken in the event that it extends within 5m of mapped seagrass beds (Refer Project Restoration Plan
Section 6.4).
4. MONITORING & MAINTENANCE
4.1. Restoration substrates to be monitored periodically and after storm events in accordance with the Project Restoration Plan.
4.2. Maintenance to be undertaken as required. This may include:
· Reprofiling and/or placement of additional rock to reinstate design levels and profiles after expected settlement has
occurred. Ideally this would occur 12 months after deployment, but may be subject to timing of other works. Where limited
settlement is experienced (nominally <200mm) and the crest remains within the target depths for oyster growth,
maintenance works are not required. Additional rock only to be placed on existing reef where monitoring indicates that this
will enhance the habitat (not where existing habitat is established and healthy).
· Placement of additional oyster cultch (seeded or unseeded) and/or live oysters, onto a reef patch. Total volume of loose
shell (including existing loose shell) is not to exceed 10kg/m2 to maximise interlocking of the cultch or oysters with the rock.
· Removal of displaced rock and or oyster shell, if found more than 5m outside the restoration site, as part of monitoring, and
if resulting in negative impacts, is required.
5. RESTORATION ZONES, RESTORATION SITES, RESTORATION FOOTPRINTS
5.1. Suitable Restoration Zones have been identified as listed below. For more detailed images of each zone, refer drawing
NROR-2021-01. The Restoration Zones have been developed based on Habitat Suitability parameters and Restoration
Suitability parameters as detailed in the Project Restoration Plan.

Zone 1. Main Channel
Zone 2. Noosa Sound
Zone 3. Weyba Creek
PHASE 1 SITE
Zone 4. Lake Weyba
Zone 5. Lake Donella
5.2. Restoration Sites are identified within each Restoration Zone based on mapping of site-specific constraints, knowledge of past
oyster bed occurrences (where possible) and adoption of minimum distances outlined in Table 1.
