The entrance to the Maroochy River migrates due to coastal and estuarine processes. Its location has been both north and south of Pincushion Island since the 1940’s.
Renewal of the Maroochy Groyne will be completed in two stages. Stage 1 will take place from April – September 2020* and Stage 2 will take place in 2021.
Stage 1: Monday 20 April – early September 2020
Work is to take place 6am to 6pm, Monday to Friday only (subject to weather and tidal conditions).
Stage 1 construction will focus on renewing the two northern-most groyne structures (Groyne #3 and Groyne #4) and the seawall surrounding the Cotton Tree Holiday Park.
- While the construction team will be on-site from 6am machinery will not operate until 7am.
- Heavy machinery including trucks and excavators will be in operation and intermittent noise impacts are to be expected.
- The construction team will try to minimise construction impacts wherever safe and possible to do so.
- Council will continue to liaise directly with the Cotton Tree Holiday Park management.
- Community access will be maintained to the beach and river in dedicated ‘safe zones’ throughout construction.
For community safety and to help works proceed as quickly as possible, some beach access, car park areas, and beach areas will be fenced off and temporarily closed during construction. Some swimming exclusion zones will apply.
Cotton Tree Holiday Park is not a public thoroughfare. General community access through the park to and from the beach is not permitted. Temporary changes to parking and community access can be viewed on the map.
Closed circuit TV (CCTV) footage is being taken of the works site. View the works progress via the Thompson Bros website.
Stage 2 will take place in 2021
This stage will focus on the two southern-most groyne structures (Groyne #1 and Groyne #2) as well as a ramp to facilitate emergency access to the north of the site. Council will keep the community updated on Stage 2 schedules closer to the expected start dates.

Southern migration in the 1990’s saw erosive pressure occur at the Cotton Tree Holiday Park.
In 2003 council constructed the groyne and sections of seawall to help protect the Cotton Tree Holiday Park and other nearby valuable assets. Some of the existing groyne structure has now deteriorated and needs to be replaced.
Renewal of the Maroochy Groyne will ensure ongoing protection of the Cotton Tree precinct from erosion.
This renewal project is the result of extensive council planning, including a 10-year Shoreline Erosion Management Plan (SEMP) developed in 2014. This plan and the groyne renewal project incorporate sound science, coastal engineering principles, community values and coastal dynamics.
Council undertook extensive community consultation when considering options for the groyne renewal in 2017. This included establishing the Maroochy River Estuary Consultation Group (which has continued to work with council on design options and testing) and seeking wider community feedback.
Council considered this feedback in determining that the existing groyne would be replaced with geotextile bags instead of rock. This consultation was recognised nationally with a 2019 Australian Coastal Award for Community Engagement.
