Hitting new heights in the Shoalhaven

🚇 Beneath Sydney’s streets, a Metro marvel is taking shape.

Deep under Hunter Street, John Holland and our partners CPB Contractors and Ghella ANZ are helping deliver one of Australia’s most ambitious infrastructure projects: the largest underground rail cavern in the country, built to handle up to 40,000 passengers an hour.

At 28 metres wide and 180 metres long, the Sydney Metro Hunter Street cavern is a true engineering achievement. With heritage buildings, tunnels and vital infrastructure just metres above, our crews are tackling complex challenges with exceptional expertise.

And recently, we hit a MEGAPOUR milestone.

The ETP Hunter Street team was buzzing with excitement ahead of the final concrete pour for the station cavern invert – so much so, they affectionately dubbed it the “MEGAPOUR.”

Over 63 hours, a massive 3,044m³ of concrete was poured continuously, a full shift ahead of schedule, with zero rejections. It’s one of the largest pours ever for Holcim Australia, and a major logistical triumph in the heart of Sydney’s CBD.

From pouring over 28,000 tonnes of concrete to shaping the future of Sydney’s transport, every milestone reflects the scale and complexity of this transformative journey with Sydney Metro and our partners – and it’s happening right beneath our feet.

👷🏽‍♀️ Building futures through education and opportunity 📚

We’re proud to kick off Year 3 of our partnership with SydWest Multicultural Services and TAFE NSW, supporting newly arrived and culturally diverse individuals in Western Sydney.

This eight-week job readiness program offers hands-on training, industry insights, and site visits - helping participants explore real pathways into construction, no matter their background.

From a warm welcome by John Holland staff to a tour of Penrith Stadium, we’re honoured to be part of a journey that builds skills, confidence, and brighter futures.

At John Holland, we believe education transforms lives, and we’re committed to helping communities thrive.

Building curiosity: Where STEM meets industry for National Science Week.

At John Holland, we’re committed to building a better future - and that means investing in the next generation. Over the past few weeks, we’ve proudly hosted three STEM engagement events across NSW, connecting students with real-world experiences in engineering, water management, and infrastructure.

💦 At Warragamba Dam, students from Westfields Sports High and Verona School got a rare look inside the dam while it was spilling, hearing career stories from our team and exploring pathways in engineering.

💦 At Cronulla, over 20 female students joined us for a hands-on STEM day focused on gender equity, led by our D4C Project team and featuring inspiring talks from our Safety & Wellness Advisor and Mechanical Apprentice.

💦 At Wollongong, students toured the Water Resource Recovery Facility, met our apprentices and advisors, and took part in interactive sessions that brought STEM to life.

These events are a powerful reminder of what’s possible when industry and education come together. We’re proud to help spark curiosity, build confidence, and show young people what their future could look like.

Connecting the Hunter – new bridge for Tomago 🚧

We’re proud to share a major milestone on the M1 Pacific Motorway extension to Raymond Terrace (M12RT) with a new Tomago bridge now open to northbound drivers.

This is the second of 11 new bridges being delivered as part of this transformative project, and the first to open in the southern section between Black Hill and Tomago.

The new bridge is a key component of the future Tomago interchange, designed to improve traffic flow, safety, and connectivity for local communities and motorists.

The M12RT project team is delivering 15km of dual carriageway from Black Hill to Raymond Terrace. The project will cut travel times between Brisbane and Sydney and change the way motorists move around the Hunter.

🎉 One year ago today, Sydney Metro City opened to passengers – what a journey! 🚇

This project was a true showcase of what John Holland does best. From tunnelling under Sydney Harbour to delivering complex underground stations and integrating new platforms at Sydenham Station, and operating the network, every part of our business played a role in bringing this city-shaping project to life.

Our teams:

✔️ Delivered the first rail tunnels under Sydney harbour through our Tunnelling and Station Excavation JV - creating some of Australia’s most complex underground station structures.

✔️ Undertook complex works to integrate Sydney Metro at Sydenham Station, including constructing a new Sydney Metro concourse and platforms, plus track, signalling, and overhead line work for the Metro to run through the junction.

✔️ Constructed Waterloo Station – the first station to successfully reach completion, despite being the last contract awarded along the Sydney Metro City alignment.

✔️ Supported testing and commissioning and led the trial running of the driverless metro network through our Operations and Maintenance joint venture – Metro Trains Sydney.

It’s been a year of faster, more accessible travel for Sydney and we’re proud to be part of it.

Since the opening, our Metro Trains Sydney joint venture has been connecting people from Chatswood in the north, through the CBD to Sydenham.

Thank you to everyone who played a part. Here’s to transforming cities!

One year of securing Cairns' water supply! 💧🎉

The team delivering the Cairns Water Security Stage 1 project marked one year of delivery recently, and there's lots to celebrate. So far the team has:

🚜 Moved more than 125,000 cubic metres of earth
🏗️ Poured more than 5500 cubic metres of concrete
🚰 More than 25% of the pipeline installed

We're proud to be partnering with Cairns Regional Council on this critical project to deliver a new drinking water supply to the Cairns community and build resilience in the existing water network.
