Woodman Point Ammo Jetty

In October 2020 as part of the $5.5 billion WA Recovery Plan in response to the COVID-19 pandemic, the Department of Transport (DoT) was allocated $9.69 million to replace Woodman Point Jetty.

  The new Woodman Point Ammo Jetty

The Woodman Point Jetty, also known as the Ammo Jetty, was originally constructed in 1903 for loading and unloading explosives. The jetty was opened for public access when the explosives magazines were closed in 1984.

Located within the Woodman Point Regional Park, approximately 9 kilometres south of Fremantle within the City of Cockburn, the jetty is one of the most used jetties in the Perth metropolitan area and is an important part of the coastal landscape south of Perth.

The surrounding beach and the existing jetty are popular for swimming, fishing, snorkelling and scuba diving. The adjacent John Graham Recreation Reserve is also popular and provides picnic and public amenities.

Sadly, the jetty is well beyond its intended life. The age and deterioration of the structure has seen the allowable load weight on the deck reduced over time. If the jetty isn’t replaced there is a risk of its collapse.

The purpose of the new jetty will be to provide all community users a safe recreational facility and like the current jetty, the new structure will not be designed for or used by motorised vessels.

  Project status

DoT has been tasked with delivery of the jetty project and is now undertaking the detailed design phase of the project. The project team initially engaged with a significant number of stakeholders to obtain their views on the replacement of the jetty.

The old jetty deck will be demolished but its concrete piles, installed in 1939, will remain due to the site’s significant heritage and popularity as a dive site in the metropolitan area.

The new jetty will provide recreational fishers and community users, a safe, fit for purpose recreational facility. Like the current jetty, the new jetty will not be designed or utilised for vessels, as this is a boating exclusion zone.

DoT engaged specialist marine and landscape planning consultants to progress the project with stakeholders’ views used to help the concept.

During August/September 2021, DoT sought input on the concepts from all community users. More than 1,000 responses were received from the broader community during this phase of the project and DoT used the information provided to develop a final concept design for the new jetty.

The concept design will be further developed in the detailed design process to be ready for construction. A specialist engineering and architecture consultant has been engaged and the detailed design is already underway.

Woodman Point Ammo Jetty Concepts:


What is the Woodman Point Ammo Jetty project?

In October 2020 as part of the $5.5 billion WA Recovery Plan in response to the COVID-19 pandemic, the Department of Transport (DoT) was allocated $9.69 million to replace Woodman Point Jetty.

A working group comprising DoT, Department of Biodiversity, Conservation and Attractions (DBCA), Fremantle Port Authority, Department of Primary Industries and Regional Development, the City of Cockburn, Fishability and Recfishwest has been formed to provide input and guide the project.

The Woodman Point Ammo Jetty is popular for swimming, fishing, snorkelling and scuba diving but is well beyond its intended life.

The project will see the demolition of part of the existing jetty and construction of a new jetty to provide all users with a safe recreational facility.

The old jetty will be demolished but most of its piles, installed in 1939, will remain due to their significant heritage and popularity as a dive site.

The areas immediately surrounding the jetty will remain closed to motorised vessels to ensure the safety of those diving and snorkelling around the new jetty.

Why is a new jetty needed?

Unfortunately, the jetty is well beyond its intended useful life. The age and deterioration of the structure has seen the allowable load rating of the deck reduced over time, but it continues to be one of the most used jetties for fishing, swimming, snorkelling and diving in the metropolitan area.

The jetty is a valued piece of coastal infrastructure given its unique heritage and popularity amongst swimmers, fishers, snorkellers and scuba divers.

By retaining elements of the old structure, the new jetty will provide a new, safer structure that will continue to be enjoyed by the community and have lasting benefits.

Was there consultation with users for the development of the 3 concepts?

Yes. In March 2021 the project team engaged with users face to face on site to get their views on how the jetty should be redeveloped and between April and June 2021 there was targeted engagement with the scuba diving, fishing and local coastal community groups. The consultation directly informed the three concepts that were published for public comment in late 2021.

The feedback from more than 1,000 responses during the public comment period was used to develop the final concept design.

What are the key features of the final concept?

The new jetty will feature significant improvements:

  • a 50 metre long, three-metre-wide T-head more than doubling the fishing space in deep water;
  • the opportunity for greater separation (four metres) between divers and fishers with a much wider main deck providing a safer environment;
  • improved access to the water from the jetty for swimmers and divers via a dedicated ramp and low-level platform; and,
  • increased protection for the valued marine biota on the existing jetty piles.

What other features will the new jetty have?

Several design elements were common to all concepts presented for community feedback. These included better lighting, rubbish bins, a swimming platform, access ramps to the water, retention of the marine biota on the existing piles, emergency access ladders, shelter, seating and shade. All have been included in the final concept for the new jetty.

Will the new jetty be as long as the current one?

Yes. The new jetty will be as long as the current jetty with an additional 50-metre-long T-head at the end to provide more than double the space for fishing in deep water.

The main deck of the jetty will also be much wider allowing more space for all the recreational activities.

A longer jetty was ruled out after it was confirmed the seabed at the location doesn’t get deeper as you go further out to sea.

The footprint of the final concept also reduces the impact on undisturbed areas compared with a longer jetty.

Has the local environment been considered?

The environmental impact of the project is expected to be relatively small. However, there are sensitive environmental factors that have been considered in the development of the final concept. The marine biota surrounding the existing piles is well recognised and highly valued. To recognise this, the final concept includes shading over the piles as protection. Seagrass adjacent to the jetty will also be protected as much as possible during construction, and the continued restriction of motorised vessels operating in the area will help to maintain the existing marine environment.

With regard to flora and fauna on the coastal strip, whilst some clearing is required to deliver the project, significant effort is being made to minimise this.

Will the new jetty cater for boats?

No. The area immediately surrounding the Jetty will remain closed to motorised vessels. Kayaks and small unpowered dinghies may use the jetty for landing.

Will the jetty be closed during construction?

Yes, the Jetty will need to be closed during construction for the safety of contractors and the public.

Feedback on this issue during the public consultation was that it was better to retain the existing piles and have a new, larger jetty even though partial deconstruction of the old jetty and construction of the new would mean no access to the jetty for a period of up to 12 months.

Will there be further opportunity to comment on the design?

Detailed design of the final concept has commenced. However, there will be specific workshops held during detailed design on key aspects. DoT will assemble key stakeholders to work through these elements to ensure the best outcomes.

However, if you have specific suggestions during this final design phase of the project please email: NewAmmoJetty@transport.wa.gov.au.

When will the jetty be built?

Construction will commence following completion of the detailed design approvals and a tender process.

How long will construction take?

Construction is expected to take approximately 12 months.

What approvals are required?

A Development Application is required and will be assessed by the City of Cockburn. In addition, environmental and heritage approvals are also required.

Will the central shaded area of the new jetty be available for diving?

Yes. The new jetty will provide even more shade over the old jetty piles than the existing structure. The new jetty will have a much wider main deck which is at least 14m wide and 77 metres long, by comparison the existing old jetty head is 9.3 metres wide by 95 metres long. The existing piles, which are covered in marine growth and will be retained, will be more shaded than they are currently.

The deck will be continuous and therefore provide better protection to divers from fishing lines. A ramp and steps will allow access for swimmers and divers to lower platforms, and to and from the water.

Will the new jetty be wide enough to walk around?

Yes. The new, wider jetty provides plenty of space to walk around the edge or through the middle and not impact on other users.

Why is there a T-head?

There was originally a 26 metre wide T-head on the old jetty which was removed in 2012 when its condition deteriorated and it became unsafe. The previous T-head was very popular as it accommodated fishing in varying wind directions generally, and specifically to target mackerel during summer easterly winds for which the jetty is famous. The final concept replicates the old T-head but will be double the length.

How will diving, snorkelling and swimming be separated from fishing?

Fishing will be possible from the outside of the main deck and from the T-head. Divers and snorkellers will be protected under the main deck away from fishing lines. Swimmers can also swim under the main deck or shoreward either side where the jetty meets the shore.
