The design and of the restoration substrate and its

qualified coastal engineers (Integrated Coastal
Management). All works will occur below Mean High
Water Spring and requires works to have NO
adverse effects on higher value marine plant habitat
including seagrass, saltmarsh and mangroves and
only temporary impacts on low value marine plants,
such as macroalgae and turfing algae, at one site,
Tewantin.
Minimum distances from marine vegetation are
specified to ensure high value marine plants are
protected (as outlined in Section 2.3, Table 2.2. of

the Project Restoration Plan and in ICM drawing
NROR-2021-00). These minimum distances have
been shown in other oyster restoration projects to be
suitable to adequately protect marine plants. This is
achieved by the project’s recent (late 2020) mapping
of all marine vegetation prior to detailed design.
The substrate design and placement are to ensure
that minimum distances from higher value marine
plants are maintained.

A small stand of mangroves is shoreward of the
proposed restoration footprint. Mangrove areal roots
extend into the intertidal zone adjacent to the
proposed restoration footprint. Mangrove roots are
excluded from the restoration footprint at a minimum
distance of 2m. Seagrass is found upstream and
outside of the restoration footprint and is excluded
from the footprint at a minimum distance of 10m from
the footprint.
According to project consultants, ESP, macroalgae
growing on rocks, dominated by Padina sp. is sparse
(less than 15% of the surface area), with a footprint
of less than 479m2. The macroalgal assemblages

were assessed as being in relatively poor condition
due to high sediment loads observed on and around
the existing rocky reef and rubble areas, with some
sections of reef having a high coverage of fine
sediment.
ESP also confirmed that given the speed at which
Padina can colonise hard surfaces (dead oyster
shell) elsewhere in the estuary, it is anticipated that
supplementary habitat provided as part of the
proposed restoration project would be colonised
rapidly within 1 year of deployment, and that
coverage would be similar to the current condition
within 2 to 3 years post deployment, particularly in
sections that particularly in sections that remain
subtidal and not covered by fine silt.
Mangroves and seagrasses are not within the
footprint of this project and will not be impacted at
any restoration site.
Alternatives to the oyster ecosystem restoration
methodology proposed are evaluated in the Project
Restoration Plan, Section 6.3. Impact minimisation
Oyster ecosystems are known to increase the
biomass of fish relative to adjacent bare habitat. They
also provided hard substrates, which are colonised

by a range of marine organisms which build
ecosystem complexity.
In 2016, Ecological Service Professionals (ESP)
quantified the historic spatial extent of oyster beds in
the Noosa River and concluded that it was likely to
have been in the range of 41,530m2 to 207,650 m2,
of which approximately 16,850m2 of old oyster beds
and oyster rubble remain buried by sediment in the
historical oyster lease areas.
The works proposed is for the restoration of 3,600m2
of oyster ecosystems in phase 1 of the project. That
equates to between 1.7 and 9 percent of the original
area.
The design of the substrates, and their configuration
on each restoration site, as the basis for ecological
restoration, also provides structured 3-dimensional
habitat that is known to support diverse fish
assemblages.
The restoration substrates are designed to fit within
the existing mosaic of available fish habitats and
improve connectivity between existing fringing marine
plant and reef habitats. In short, the works help
restore the mix of substrates and habitats that once
occurred in the estuary, a diversity which has largely
been forgotten against a background of estuary

modification, the extent to which can hardly be
accepted.
The restoration sites are in areas that are within the
modern recruitment, growth and survival envelope for
natural rock oysters in the estuary, and supplement
hard structure, of suitable design, which rock oyster
ecosystems require as their foundation for
establishment in the modern estuarine environment.
The restoration substrates need to be of a size,
configuration, rugosity and heterogeneity, which
support a diversity of species. TNC ecologists
confirm that these substrates meet these criteria.
The substrates must also be stable (not move from
site), durable, minimise sediment trapping, maintain
natural laminar flow of river currents, avoid erosion of
shorelines and maintain fish passage. The engineers
certify that substrates as designed and placed on the
restoration sites meet these criteria.
The drawing show concept models, which are
important to set design and construction parameters
for how patches of rock (or rock and shell) sit on site
and are positioned relative to each other. However,
when placed onto specific restoration sites, these
modules are flexible in their application. This means,
when placed onto each restoration site, a module

may comprise a few or many rock or rock/shell
patches. These may be laid in a single row along a
shoreline or as multiple rows, offset from each other.
The number of rows reflects the bathymetric contours
of the individual site. High relief slopes can only
accommodate a single row of patches, low profile
slopes can accommodate more rows. The width of a
site is primarily guided by water depth, which cannot
exceed 2m below MHWS.

ensures fisheries resources and fish habitats return restore once prolific oyster reef habitat, which was

activity has ceased. provide significant habitat for a range of fish species
and improved habitat condition.
The processes for restoration are as per the
guidelines of the international Society for Ecological
Restoration (SER).
Once the oyster reef patches are in place in the
restoration sites, natural recruitment of oysters
should commence. The oysters themselves are
expected to reach maturity and commence spawning
within three years of settlement. By year 7 at least
two generations of adult oysters should be thriving on
the oyster reef patches and a mixed community of
other shellfish species, macroinvertebrates and
marine plants likely to occur. The area of coverage of
oysters is expected to exceed 50 oysters per metre.
If this is not achieved, then the site will be augmented
with hatchery spawned local oysters until this
coverage is achieved and intergenerational
recruitment of oysters from natural processes to the
reef recorded.

marine plants encountered on the tidal flats are further
protected by a 2m separation area between them and the
oyster reef patches as per the Project Restoration Plan
(Section 2.3, Table 2.2., line 1).
The proposed works are designed to minimise the potential
for erosion of the park shoreline. On the contrary, it is
expected that the works may enhance protection of the
park shoreline by attenuating some wave action due to the
high rugosity and positioning of the oyster reef patches,
which will attenuate wave energy before it reaches the
shoreline at all but the highest points of the tidal cycle (see
Project Restoration Plan, Section 8.4. Erosion control).
