Our team and towers are built for an Australian future where connecting our communities safely and reliably is more important then ever before.


We never compromise on health and safety. 

We aim to meet or better global standards. 

We are proud to have achieved multiple International Organisation for Standardisation (ISO) certifications and standards including ISO 9001 (quality management system), ISO 14001 (environmental management) and ISO 45001 (occupational health and safety).

Stilmark works closely with our customers and contractors to maintain the highest levels of safety and security across all of our sites and construction projects. As a member of the Critical Infrastructure Centre, Communications Sector Group, we are also closely aligned with Industry best practice to keep Australia's infrastructure secure.


Our approach is designed to minimise and mitigate potential impacts at the local level of our operations. We are committed to the two degree target of the United Nations. We operate our business in a manner that reduces our impacts on the environment, prevents pollution, and protects the environment and resources. We manage the life cycle of our installations in an environmentally responsible manner.

We maintain full compliance with applicable environmental laws, regulations and other obligations and are proud to have achieved ISO 14001 (environmental management) environmental management certification. When our own requirements are more stringent, we operate to these higher standards. We require this same compliance from our business partners and contractors. 

We continually evaluate and review the impact of our business on the environment, set goals to reduce these impacts, and measure our progress.  


Stilmark is committed to providing high quality telecommunications services and products in accordance with community and client expectations.

Stilmark systematically controls and assures the quality of works and services through the achievement of organisational quality objectives, application of industry best practice and the continual improvement of our quality management system (QMS). Our QMS is aligned to the requirements of ISO 9001 (quality management system).

Inclusion and diversity

Our differences are what make us unique. At Stilmark, we are proud to employ a team of diverse and interesting people regardless of their gender, race, religion, nationality and age. 

Our philosophy is rooted in this idea. We seek to find and retain the best talent no matter who you are or where you come from.


Central to the way we work is our value of Integrity Always.

We believe high standards of governance are critical to creating long-term value for our customers, suppliers, people and the communities where we operate.

Even though we are a young company, we aim to be a leader in corporate governance and ethical business conduct, by maintaining best practices, transparency and accountability with our stakeholders.

Our board of directors has established clear lines of authority and oversight over our corporate responsibility programs.  

Security and resilience

The security and resilience of telecommunications infrastructure is of the utmost importance to our customers, and the communities that depend on them. We have a permanent Director of WHS, Risk and Security, to rigorously assess our operations against the highest standards on a regular basis, and maintain close relationships with security and infrastructure resilience bodies, including:

  • Member of the Critical Infrastructure Centre's Trusted Information Sharing Network (TISN), Communications Sector Group (CSG). Stilmark is the only telecommunications infrastructure company that is a member of the CSG.  
  • Member of ASIO's Outreach program.  
  • Assessed operations against Australia's Critical Infrastructure Resilience Strategy, the National Guidelines from Protecting Critical infrastructure from terrorism (ANZCTC), and the NSW Critical Infrastructure Resilience Strategy.  

Picture taken Nov 2020 shows our site at Mt Moonbi, NSW covered in pink fire retardant as applied by the NSW Rural Fire Service. Thanks to the bravery and coordination of all the emergency services across Australia, our critical infrastructure was kept operational to support the local community and emergency services in the effort to manage the bushfires in the area.
