2026 marks a defining milestone for Harrison Infrastructure Group — 30 years of continuous operation, growth, and contribution to the communities and clients we serve. On Wednesday, we officially celebrated 30 Years of HIG!

Our teams across Brisbane, Toowoomba, Rockhampton, Bundaberg and Sunshine Coast each celebrated with morning teas, balloons, and excitement for the future.

Our 30 Year journey is not measured simply in projects delivered or kilometres designed, but in the relationships we have built along the way. Our long standing client partnerships, repeat collaborations, and enduring professional respect have been the foundation of our success, and drive.

To our clients and collaborators, we say a huge thank you for everything throughout the years, and we look forward to delivering continued innovative change together.

This milestone is a celebration of our people, past and present. Our team’s expertise, commitment, and desire to grow have ensured that HIG has never stood still. It is this collective effort that has created a legacy of excellence.

The same curiosity, professionalism, and resilience that carried us through the past three decades will define the next. With a strong team, trusted clients, and a clear focus on quality and innovation, Harrison Infrastructure Group enters its fourth decade with confidence and purpose.

Thank you to everyone who has been part of our journey so far. Here’s to 30 years of Engineering Excellence and many more ahead.
