While the project delivery environment in which we operate is highly dynamic, our approach to working with our clients is based on an unwavering commitment to our company values.
It is these values which bind the team and focus our efforts to overcome the challenges faced each day, whether these are encountered onsite, on the road, or behind the scenes at DEMEX’s headquarters in Southeast Queensland.
In addition to striving to maintain the highest standards of safety and professionalism, we continue to learn and look for ways to innovate in our systems, technology, and equipment. One important key to how we do this is taking lessons learned and applying them to the advantage of our clients. It is this willingness to transfer knowledge back into the field that reflects our value to collaborate and connect, ultimately creating a stronger community of colleagues, clients, and contractors.
Having expanded our services and capability across diverse sectors, our objective is to provide complete solutions for clients who require the removal of assets to make way for site remediation or commercial development.
From demolition planning required for asset closure or early contractor involvement, through to decommissioning, deconstruction, and remediation applying circular economy principles, our experience, team, and approach continue to set us apart.
As we continue to move into the resources, oil and gas, and energy sectors, we are building on the team’s capability and experience in heavy industry and commercial demolition strengthened by strategic partnerships in materials recycling.
This company profile provides a high level view into our business, however, I encourage you reach out to our team directly to learn more about how we can work with you to achieve your project and business objectives

Our leadership team sets the foundation for how we work together. They demonstrate the the overall approach to business through:
• Resourcefulness

Project estimating, planning, and management is undertaken by a core group of professionals located at DEMEX’s head office in South East Queensland, with many of the team bridging both site and project management roles.
We operate extensively throughout coastal, regional, and remote Queensland and New South Wales, and continue to expand across Australia through projects and delivery partners as opportunities present.
Together with our delivery partnets, we strive to conduct our business in an ethical and responsible manner. Our approach to sustainability commitments balances cultural, economic, environmental, and social considerations.
DEMEX maintains a strong sustainability track record with resource recovery solutions for projects including screening for waste minimization, scrap metal processing and recycling, precious metal segregation and salvage, onsite concrete crushing for reuse, and remediation techniques to reduce landfill exposure. Our environmental management approach is tailored according to project needs and in keeping with all relevant legislation and regulations.
As the projects we deliver take us to diverse communities in urban, regional, and remote locations, we understand the responsibility conferred upon us to ensure meaningful economic and social outcomes are realised by local businesses and the broader community. The approach taken is underpinned by compliance with relevant legislation, such as the Commonwealth Modern Slavery Act for supply chain integrity, and by forging commercial relationships with our Australia wide network of prequalified suppliers and contractors.
The importance of meeting our obligations to Indigenous Australians is well understood. Accordingly, we have implemented an Indigenous Employment Strategy (IES), which details our commitment to creating employment opportunities for Indigenous Australians. In conjunction with our Indigenous cultural advisor, we seek to create employment opportunities that help build competency and confidence in the individual.
