One Mile Jetty Repair/Replacement

One Mile Jetty Community Survey

The Commission are currently conducting a community consultation survey. This is the communities chance to have a say on how they would like the $4.5 million of State funding to be spent in the next phase of the One Mile Jetty Repair/Replacement Project, stage two.

Follow this link to take the 1-minute survey, survey will close 8 April 2022: https://www.surveymonkey.com/r/THS3TX3

Project Overview

The One Mile Jetty Repair/Replacement project is a three-stage project: stage one, deconstruction, is being led by the Department of Transport; stage two, reconstruction to the value of $4.5 million, is being led by the Gascoyne Development Commission; and stage three pursuing further funding is being led by the Shire of Carnarvon.

The One Mile Jetty Repair/Replacement, Stage 2 aims to deliver a significant tourism asset for the region that celebrates the significant value the Jetty holds in Carnarvon’s history and honours the memories and connection to the Jetty that the community holds dear.

Project background

Constructed from 1897, the One Mile Jetty has been integral to the cultural identity of Carnarvon and played a significant role in the economic development of the Gascoyne region. The State Heritage Register’s listing of the One Mile Jetty recognises its significant historical value.

The Jetty is located on the southern side of the entrance to the Gascoyne River in Carnarvon at the site of the 1890’s Port of Carnarvon.  Carnarvon was one of the first recorded ports in the world to load livestock on board ships for transport to markets. The Jetty was also the departure point for Aboriginal people proceeding to the Lock Hospitals of Dorre and Bernier Islands.

The current Jetty custodians are the Carnarvon Heritage Group, a not-for-profit organisation.

Following several fires and adverse weather events, the Gascoyne Development Commission, on behalf of Heritage Group, commissioned a structural assessment report in 2017 which deemed the Jetty unsafe and it was consequently closed to the public. Since its closure, a broad community campaign has been led by Heritage Group to identify a solution to its usability and sustainability.

Visitors to Carnarvon can explore the fascinating history of the iconic Jetty at the Carnarvon Heritage Precinct’s One Mile Jetty Interpretive Centre which was officially opened by Minister for Regional Development, Alannah MacTiernan on 17 April, 2019.

The further development and preservation of the Jetty and the Heritage Precinct will contribute to the resilience and diversity of WA’s tourism industry and actively contribute to a broader regional economic base for the Gascoyne.

The Commission established a Community Reference Group with members from Carnarvon Heritage Group, the Shire of Carnarvon, Department of Transport, Department of Planning, Lands and Heritage and Traditional Owners to investigate options for the future of the Jetty and the surrounding Heritage Precinct.

In 2020, the Commission engaged consultants Acil Allen to develop options for repairs and/or replacement of various lengths of the Jetty. Twenty two high-level conceptual options were identified for the repair of the Jetty. The State Government subsequently committed $4.5 million to kick start the Jetty repairs.

On Sunday 11 April 2021, Tropical Cyclone Seroja severely damaged large parts of the Jetty and destroyed around 360m. It is estimated that 200-300 tonnes of timbers were carried south by prevailing currents causing a marine hazard.

The level of damage has necessitated the development of a staged approach to the preservation of the Jetty.

Stage One

Following an engineering report recommending removing all but the first 400 metres of the Jetty, the Department of Transport was the leading agency to deconstruct and salvage timbers from the intertidal section onwards (Piers 117-245). These deconstruction works were completed late 2021.

Salvaged timbers from the Jetty will now be individually assessed for heritage value, quality, and structural integrity. High to low-grade timbers may have the potential for reuse in the One Mile Jetty Repair/Replacement, Stage 2 or other community projects.

Stage Two

Stage two of the Project is underway with community consultation progressing. The State Solicitor’s Office has also been engaged to provide legal advice.

The Commission continue to work with key stakeholders through a project steering group which includes the Department of Transport, Department for Planning Lands and Heritage and Carnarvon Heritage Group. A community forum was held in September 2021, where the community was updated on each stage of the Project.

For more information, see publications below.

Stage Three

The Commission is continuing to investigate funding opportunities to extend the One Mile Jetty to deep water. Work on a new business case has started to explore the possibilities of developing the Heritage Precinct further.

Frequently Asked Questions

Q. Will the Jetty be re-piled/built?

Yes, the Jetty will be rebuilt using modern piling techniques. With new technology and modern design techniques, the new Jetty will require fewer piles. The Commission currently have funding to repair and replace a limited portion of the original Jetty. The Commission are currently working with stakeholders to seek more funding so more of the Jetty can be replaced in the future.

Q. Which company was contracted to deconstruct the Jetty?

The Department of Transport was the responsible agency for the deconstruction of the Jetty, seaward past the beach. TAMS Australia was the main contractor engaged to complete the works.

Q. Will local Gascoyne contractors be employed for Stage 2 of the project?

It is Commission’s preference to use local contractors where possible. The complex nature of the project and specialist skills required may make it difficult to engage local contractors directly. The Commission's Project Manager is working closely with the Gascoyne Local Content Advisor to ensure local contractors are engaged wherever possible.

Q. How long will Stage 2 of the project take to complete?

Planning and preparatory work has begun and is expected to be completed around mid-2022. Construction for stage 2 works is expected to start in the second half of 2022
and will take about 12 months to complete. New geo tech information for the site, adverse weather, and the impacts of COVID-19 may prolong these timeframes.
