At John Holland, our purpose is simple: we transform lives with everything we do.

💦 Water: it’s in our blood.


Over our 75-year history, we’ve never been afraid to get our hands dirty - or wet, for that matter.


We’re proud of the role we’ve played in securing Australia’s water future through projects like the 270km-long Wentworth to Broken Hill pipeline in western NSW, the Chaffey Dam and spillway near Tamworth, and the Sydney and Gold Coast desalination plants.


Along the way, we’ve built long-term relationships with some of the country’s largest water authorities, including @melbournewater, @sydneywater, @QueenslandUrbanUtilities and @sawatercorp


Today, as Australia’s premier water and wastewater contractor, we continue to deliver innovative, value-driven solutions for our customers – projects like the Upper South Creek Advanced Water Recycling Centre and the North West Treatment Hub package for Sydney Water; the Western Treatment Plant for Melbourne Water; the Cairns Water Security package for @cairnscouncil; the Lake Macdonald Dam upgrade for @seqwater on the Sunshine Coast; and the Belmont Desalination Plant for @ourhunterwater


🚰 And while it just so happens to be National Water Week, join us in raising a glass to H2O!

If you're an engineer, this brain teaser has got to beat guessing the number of jellybeans in a jar! 🤔



How many precast concrete segments are being produced for the Sydney Metro West tunnel between The Bays and Hunter Street?


😮 16,536 segments are needed, and we've produced more than 8,000 so far!

Our tunnel boring machine (TBM) Jessie, who started chewing her way towards Pyrmont in June, has completed more than 650 metres of the 2.3-kilometre journey towards Hunter Street in the CBD, so these segments are being installed in the tunnel behind her under Johnston Bay.



We know it's hard to know what's going on underground, but these photos show you how the segments are laid into place to become the tunnel you'll be travelling through one day!

And while you've been counting the segments, we've just laid another piece of the tunnel puzzle.

Its exhibitions feature images of some of the most iconic Australians, so it's only fitting that the National Portrait Gallery is one of the nation's most iconic buildings!

🏛️ Completed in 2008, the National Portrait Gallery is the most significant building constructed in the Parliamentary Triangle in the past 20 years.

✨ The gallery's striking off-white "bush-hammered" concrete finish was achieved by the John Holland project team using a refined method of shot-blasting, designed to match some of the finishes on neighbouring structures.

👩‍🎤🎨 The gallery features portraits of everyone from actress Deb Mailman to Denmark's Princess Mary and is visited by around half a million people a year! We hope they enjoy the building as much as the art!

We're proud of the work we've done over the past 75 years of delivering cultural institutions and public spaces.

We’re proud of the way our people help other Aussies in times of need, and Nigel Ferguson is a great example of this.

🌪️ When Cyclone Jasper hit Far North Queensland in December 2023, widespread flooding caused heavy vehicle access to be cut off from the Atherton Tablelands and north to Cape York. Nigel, then based in Cairns as a Senior Supervisor on the Edmonton to Gordonvale project (E2G), called off his annual leave and rallied his John Holland and subcontractor colleagues to help get the Palmerston Highway reopened, allowing vital supplies to get through to some of the worst-hit areas.

🚧 E2G was a complex project which included duplication of 10.5km of the Bruce Highway to four lanes, new service roads, relocating 4.4km of Queensland Rail Line, two new level crossings, and relocating and constructing 8.8km of cane rail. The project was completed on time and under budget in late 2023.

🤵 Nigel was named John Holland employee of the year at our annual awards last week for this act as well as his day-to-day professionalism, kindness, and attention to safety.

🏆 The awards are held to recognise the many John Holland people who go above and beyond every day.

For 75 years, John Holland has been transforming lives – and it's hard to think of a building more life transforming than a new hospital 🏥.

John Holland's history of building hospitals and critical health infrastructure began in the Top End in 1979, with Darwin's Casuarina Hospital.

Construction was originally planned to begin in 1974 – the year that Darwin was decimated by Cyclone Tracy. After supporting Territorians in the aftermath of Australia's deadliest cyclone, John Holland got to work on the Casuarina Hospital in 1976, ahead of it opening in 1979.

Since then we've built or upgraded hospitals right across the country, including the Perth Children’s Hospital, the Calvary in Adelaide, Australia's first dedicated cardiac facility, the Victorian Heart Hospital, and Stage 1 of Logan Hospital in Queensland.

Today we have more than $3 billion worth of health infrastructure projects underway.

We're proud of the role we're playing in keeping people safe and healthy 🙌😊.

💧 We're up for the challenge to help secure water supply in the Hunter!

In what's set to become a key component of Hunter Water's Lower Hunter Water Security Plan, John Holland will deliver the $460 million Belmont Desalination Plant, as part of the $530 million scheme south of Newcastle.

With the capacity to supply 15% of the Lower Hunter's average daily needs - or up to 30 million litres of water every day - this state-of-the-art plant will be a game changer for the communities of this major NSW region.

From delivering the Gold Coast Desalination Plant in 2009, to the Sydney Desalination Plant in 2012 and several smaller desalination projects in South Australia more recently, we've got the expertise and capability to deliver another transformational outcome in water security.

We're thrilled to sign the contract with Hunter Water and look forward to starting work before the end of the year!

For 75 years we’ve been building vital infrastructure that connects communities and keeps people moving in their city.


In 1978, we completed construction of Melbourne’s iconic West Gate Bridge - a 2.5km bridge that crosses the city’s Yarra River, and sits 58 metres above the water.


To this day, the West Gate Bridge remains the only direct link between Melbourne’s CBD and the western suburbs and is one of the country’s busiest road corridors carrying up to 200,000 vehicles a day.


But fast forward 45 years and that’s about to change - we’re building another vital link for Melbourne’s west, the West Gate Tunnel Project.


More than 6kms of twin tunnels from the Maribyrnong River under Yarraville to the West Gate Freeway will provide commuters a much-needed alternative to the West Gate Bridge.


The project also includes a widened West Gate Freeway and more than 15 kilometres of new bridges and elevated road showcasing how we transform lives, whether it be above ground or below.


The West Gate Tunnels are expected to open in late 2025.
