This project consisted of maintenance dredging of navigation channels in the Broadwater on Queensland’s Gold Coast. The scope included removal of 110,000m3 of sand from the north and south channels as well as South Wave Break Island channel.

Birdon used a cutter suction dredge to remove sand from the North Channel and pump it, via a temporary pipeline, across the southern tip of South Stradbroke Island. It was then discharged into the ocean-side tidal zone.

The sand from the South Channel and South Wave Break Island Channel was pumped to the stockpile on the spit for storage and future beach renourishment. Birdon delivered the project without disrupting existing waterway users.
