Construction of geotextile groyne.
Stage 1 of this beach replenishment project undertaken in 2001 involved
the dredging of 100,000m3 of sand from near the mouth of the Maroochy
River (utilising the dredge 'Kikilu') and placement along a 1km
stretch of eroded beach to the south of the river mouth.
The remedial works also involved the construction of a single
100m long geotextile sand-filled groyne to help reduce future
erosion along the beach.
