Serving Diverse and Demanding Industries

At 1 Service Group, we understand that no two environments are the same—especially in sectors where safety, uptime, and compliance are non-negotiable. That’s why we provide specialised maintenance, upgrade, and compliance services tailored to the unique needs of critical infrastructure.

Our team proudly serves a broad range of industries, including:

• Road Tunnels – Expert maintenance of fire protection, plumbing, and ventilation systems in confined, high-risk environments.

• Metro and Rail Networks – Reliable, standards-compliant asset servicing that keeps transport systems running safely and efficiently.

From preventative maintenance and system upgrades to full compliance support, we bring deep experience and innovative thinking to every project. Our team is equipped to manage the intricacies of each environment, with a strong focus on safety, sustainability, and long-term performance

Commitment to Quality, Safety, Environment & Inclusion

At 1 Service Group, quality isn’t just a standard—it’s the foundation of everything we do. Our integrated management systems are fully certified to ISO 9001 (Quality Management), ISO 45001 (Occupational Health & Safety), and ISO 14001 (Environmental Management), reflecting our unwavering commitment to excellence, safety, and sustainability across all operations.

These internationally recognised certifications ensure that every project we undertake—whether in a tunnel, transport hub, or commercial site—is delivered with consistency, compliance, and care for people and the planet. Through rigorous auditing, continual improvement, and stakeholder collaboration, we maintain the highest levels of accountability and performance.

Equally important to our success is our diverse and inclusive workforce. Our team proudly includes Indigenous Australians, women in trade and technical roles, and professionals from a variety of cultural backgrounds. We believe diversity drives innovation and resilience, enabling us to better serve the wide range of communities and industries we support.

Together, our systems and people position 1 Service Group as a trusted, forward-thinking partner for critical infrastructure maintenance and compliance services.
