Exmouth Marine Infrastructure

About the Gascoyne Development Commission

Project name: Exmouth Marine Infrastructure

Project description: The delivery of safe and reliable marine infrastructure in Exmouth.

Project objectives:

  • Facilitate regional economic growth by providing a reliable berthing solution for visiting cruise ships.

Current phase: On hold

Completion: Phase 1 complete

Exmouth is widely acknowledged by the cruise industry as a transformational cruise destination capped by its status as World Heritage Area. With its ‘bucket-list’ tourism experiences, strategic north-west cape location and proximity to South East Asia, the ability to bring Exmouth on-line as a guaranteed transit-port will be the evolution of Western Australia’s cruise sector and an economic imperative for the State.  However, Exmouth does not possess suitable and reliable marine infrastructure.

The current Exmouth Boat Harbour is designed to service recreational and commercial vessels up to 35 metres in length.  Cruise ships anchor offshore and transfer patrons to shore using tender vessels, a lengthy process that is vulnerable to windy weather. To redress this gap and provide integral job-creating infrastructure, the Commission has investigated a range of solutions and sites.


  • In June 2019, ACIL Allen Consulting was engaged by Gascoyne Development Commission to undertake an Options Assessment and Economic Benefit Assessment of options to invest in new marine infrastructure at Exmouth. To assist in this task, ACIL Allen engaged marine engineering firm BMT Group to provide engineering advice and analysis. This included the development of initial concept drawings.
  • Overall, the study found that there are likely to be net benefits to Western Australia associated with the provision of the new marine infrastructure in order of between $128 million and $154.1 million over the life of the new infrastructure. In a Benefit Cost Assessment framework, the Benefit Cost Ratio of the new infrastructure is estimated to be between 1.99 and 2.52 –
  • ACIL Allen estimates that nearly 700 full-time jobs will be created and sustained as a result of the infrastructure; with 70 of those created in the Gascoyne region.
  • An interagency Steering Group has been formed to help define and realise key economic opportunities, identify risks, and contribute to the acceleration of the project.
  • Phase 1 of the project is complete, and further phases are on hold as the market-led Gascoyne Gateway project progresses.

The Exmouth Marine Infrastructure Project will provide essential infrastructure to enable Exmouth to take advantage of its geographical location and create a vibrant new business environment for Northern and Western Australia.
