incorporated in the design of the works to mitigate
these risks:
- Oyster shells to be encapsulated in coir bags to
limit exposure of sharp edges in the short term.
As the oyster reefs develop into natural reef
systems and the coir deteriorates this benefit will
be reduced, but by this time it is expected that the
oyster reefs will be a more recognised part of the
natural Noosa River environment and public
awareness will have increased.
- Coir bags have apertures sufficiently small to
retain whole oyster shells (and prevent scattering
of shells across the seabed)
- Coir bags are stacked and clustered to minimise
the initial area of the reef units and trigger
awareness of the presence of reef units.
- Coir bags are secured to the seabed to reduce the
risk of migration of the coir bags into other areas
as a result of waves or flows.
- Adopted water depths are such that reef units are
expected to be visible during periods of

reasonably water clarity (when use of the
foreshore is more likely).
- Reef units have been located away from popular
recreation areas and often in areas with limited
accessibility, where usage of the foreshore is low.
At Site 16 (Lake Weyba) it has been located at the
northernmost end of the foreshore.
- As the project intends to reinstate a small part of
what was previously extensive oyster reef habitat,
these risks are not new to the Noosa River system
and would be at a much smaller scale to what was
previously experienced.

foreshore although it is expected that tidal and flood
flows are dominant in most locations.
No modelling has been undertaken, however it is
expected that impacts would be relatively low given
the location close to the bank and the relatively small
footprint of the works. The units are angled to the
peak flood velocity to reduce impacts and oriented to
deflect ebb tide and peak flood flows toward the
channel (rather than toward the bank) to avoid
concentrating flows which might result in erosion of the
riverbank.
Localised build-up & scour is expected however the
proposed works are flexible and able to accommodate
minor changes. The majority of the sites appear
relatively stable with no sand ripples although aerial
photography indicates that they can be subject to
change. Significant sedimentation to the point of
burial is not expected. Sites 9 & 10 could potentially
experience the greatest changes, particularly in the
event of re-opening of the channel along the western
bank.
The works incorporate quarterly monitoring for the first
3 years and if any erosion or excessive accretion are
observed these can be evaluated and the reef units
can be modified, relocated or removed if necessary.

standard mentioned in paragraph (a).
During the initial recruitment period, stability is
provided by temporary materials (Coir, Manilla Rope &
Timber). These materials are biodegradable and do
not form part of the permanent structure. The life
expectancy for typical coir logs of this size is nominally
2 – 3 years however for periodically submerged coir
bags filled with oyster shell this could potentially be
shorter and is expected to vary between sites.
Where recruitment and cementing of the reef substrate
is adequate, reefs will successfully become
established prior to degradation of the coir product. In
cases where recruitment or cementing of the reef unit
is too low, reefs may not become successfully
established within this timeframe and oyster shell may
become uncontained.
Coir is naturally resistant to abrasion, however the risk
of damage is further reduced by filling the bags using a
sleeve and ensuring the bags are well packed to
prevent migration of shells within the bag.
The works incorporate quarterly monitoring for the first
3 years and if any erosion or excessive accretion are
observed these can be evaluated and the reef units
can be modified, relocated or removed if necessary.
