RECOMMENDATION
That Council note the report by the Project Coordinator – Flooding, Coastal and Foreshores to
the Services & Organisation Committee Meeting dated 8 May 2018 providing an update on
Noosa Spit Foreshore erosion.


REPORT
This report provides an update to Council regarding ongoing erosion at the Noosa Spit foreshore.
Councillors will recall that in August 2017, the following resolution was passed:
That Council note the report by the Project Officer to the Services & Organisation Committee
meeting dated 8 August 2017 providing an update on erosion at Noosa Dog Beach and request
staff seek expert advice on the management of this area into the future, with a further report to
come to Council once that advice has been received.
This report provides Council with more information about how expert advice will be formalised via
a Shoreline Erosion Management Plan.

1.                       Background

The Noosa Spit was established by the Queensland Government’s Beach Protection Authority
(BPA) in 1978 as part of the BPA’s “Scheme for the Protection of Hays Island and Restoration of
Noosa Beach”. The function of this scheme was to protect Hays Island (now Noosa Sound) as a
result of “severe erosion occurring along the northern revetment”.

The Noosa Spit has worked effectively as a defence for Noosa Sound since its creation nearly 50
years ago until 2010 when the Sunshine Coast Regional Council (SCRC) responded to severe
erosion that was occurring at the north facing beach of Noosa Spit known as “Dog beach”.
SCRC constructed both a geotextile sand container groyne and a submerged training wall in
2012. The works were originally designed to be implemented in two stages, with stage 1
designed to arrest erosion in the most critical area, the western end, which was eroding at a rate
of 15m/year. A second stage of these works were designed and partially deployed.
