The Western Basin Dredging and Disposal Project, undertaken by Gladstone Ports Corporation, was completed in September 2013.

The project removed a total of 22 million cubic metres of material over the last two years with works finishing 12 months ahead of schedule.

The project will increase port access by deepening, widening and creating new shipping channels with depths of up to 13 metres to allow vessels to enter and exit the Western Basin. The project also included the construction of a bund wall and 264 hectare reclamation area at Fisherman's Landing.

Environmental studies around the harbour will continue until 2021, with Gladstone Ports Corporation spending appoximately $17 million in environmental study projects such as the Biodiversity Offset Strategy and Marine Fish Habitat Offset.

GPC is actively collaborating with researchers and associations such as the Great Barrier Reef Marine Park Authority (GBRMPA) and Gladstone Healthy Harbours Partnership (GHHP) to ensure future monitoring programs are relevant and provide effective measurement of the heath of the Gladstone harbour.

Future dredging works may be scheduled for further developments on Curtis Island or in the Western Basin area.
