At DEMEX, health, safety, environmental performance, and quality assurance are central to the way we deliver demolition and construction projects across Australia. Our HSEQ policies and procedures protect workers, subcontractors, site visitors, and the community, while ensuring full compliance with Australian legislation, industry standards, and regulatory requirements.

Project specific HSEQ plans are prepared and detail how DEMEX will comply with its obligations and meet company HSEQ goals and objectives during project delivery. These detailed plans include:

Legislative and regulatory compliance
ISO 14001:2015 environmental management systems (Certificate No. 418081E)
HSEQ objectives and targets
Safety training and site inductions
Hazard and risk assessment

Incident prevention and reporting
Subcontractor safety management
Environmental controls and waste management
Quality assurance and compliance monitoring

We also operate under a formal Hazard Identification, Risk Assessment and Control procedure aligned with the Federal Safety Commissioner’s WHS Accreditation Scheme (FSC Accreditation). All incidents, near misses, and non-conformances are recorded and reviewed to drive continuous improvement.

Our structured approach to HSEQ gives clients confidence that safety, compliance, and environmental responsibility are actively managed throughout the demolition and construction lifecycle, supporting safer, cleaner, and more efficient project delivery.

Industry Recognition in Safety Excellence

In 2020, we received an Australian Workplace Health & Safety Award for developing a comprehensive safe system of work at the Mulwala Explosives Facility, where our team successfully demolished 47 buildings across two complex projects. Our approach to hazard remediation and safe demolition practices also saw the project shortlisted in the World Demolition Awards 2020 (Industrial Demolition).

More recently, we won the Best WHS Technology Innovation (<1000 employees) award at the AWHSA for the demolition of the Kalamia Sugar Mill chimney stacks, recognising our innovation, engineered methodology, and commitment to safety in a high-risk, live facility environment.

These achievements reflect our ongoing commitment to health, safety, environmental performance, and quality across every demolition and construction project we deliver.

DEMEX has received Federal Safety Accreditation (FSC) for the completion of projects that fall under the scope of the Australian Government building and construction Work Health and Safety Accreditation Scheme (Accreditation number 598).

DEMEX has been formally registered on the second release of the Prequalification (PQC) System for contractors managed by the Department of Housing and Public Works (Registration number 4624). Demex has obtained a PQC rating of level 3 with a maximum contract value of $5,200,00.00 per contract.

DEMEX is registered as a supplier of demolition and asbestos services works on the buy.nsw procurement portal to undertake works for the NSW government.

In addition to our core services in decommissioning, demolition, hazardous materials removal, and civil works, we also provide integrated resource management solutions. This includes the onsite crushing, screening, and processing of discarded materials to ensure they are managed safely, efficiently, and with minimal environmental impact.

Through our partnership with Terreco Resources, we extend the lifecycle of construction and demolition waste by recycling and repurposing it back into the construction industry. Our objective is to recycle 90 percent or more of all onsite materials, maximising resource recovery and ensuring any residual waste is directed to licensed, compliant facilities.

Our team maintains an unwavering commitment to addressing unexpected challenges within the framework of project budgets, schedules and robust systems. We draw from our internal capabilities, resources, experience, and the capacity to innovate, adapt, and overcome, which is integral to the DEMEX culture.

We continually invest in the highest quality equipment and machinery, with acquisitions in low emission technology expanding our fleet and allowing us to make greater inroads to reducing our carbon footprint, and helping our clients to do the same.

Two DEMEX projects have been shortlisted for the 2025 Demolition and Recycling International (D&Ri) World Demolition Awards.

Kalamia Sugar Mill has been shortlisted in the Contract of the Year (US$1M+) category: the demolition of the towering boiler stacks at Kalamia was as complex as it was high-risk. Through early involvement, precise engineering and a focus on safety, our team delivered a project that reflects the technical expertise and innovation DEMEX brings to every site.

Acacia Ridge Business Park has been shortlisted in the Recycling & Environmental category: at Fox Road, we delivered a comprehensive enabling works program, including hazardous materials removal, demolition, and civil works, setting a benchmark for environmental performance and resource recovery in the industry.

One of two DEMEX projects to be shortlisted for the 2024 Demolition and Recycling International (D&Ri) World Demolition Awards, DEMEX shared a win with Priestly, receiving the award for Contract of the Year Under US$1M for the resort clean up of Wild Duck Island.

The Wild Duck Island project presented significant challenges. Located 23 kilometres northwest of Stanage on the Central Queensland Coast, the project required extensive planning and on-the-job innovative solutions. DEMEX’s team overcame the constraints of transport by road and sea, extreme seasonal tides, cultural heritage protection requirements, environmental and degraded waste from demolition in a remote location where all accommodation, power, food, water, and communication services needed to be brought in.

In addition to Wild Duck Island, DEMEX was shortlisted in 2024 for a World Demolition Award in the category of Civil Contract of the Year for the Palm Beach to Tugan M1 Upgrade project. DEMEX safely demolished seven bridges over a five kilometre stretch of the Pacific Motorway between May 2023 and May 2024.

DEMEX was awarded an Australian Workplace Health & Safety Award in July 2021.

Nominated for the Small to Medium Enterprise: Health & Safety Excellence Award, DEMEX demonstrated excellence in the context of a comprehensive safe system of work that seeks to adopt higher order controls and contemporary approaches to health and safety management.

DEMEX’s commitment to excellence was recognised with our Mulwala Explosive Facility (MUL037) project winning a 2020 World Demolition Award as judged by global industry leaders.

The World Demolition Awards are judged against primary criteria that include overall professional / expertise, overcoming challenges, financial and schedule management, safety performance and client satisfaction.

DEMEX was shortlisted for a 2021 World Demolition Award as judged by global industry leaders.

The demolition of the Chinaman Creek Bridge in Cairns, as delivered by Demex in early 2021 shortlisted in the Contract of the Year Under US$1 Million category.

We’re committed to creating real opportunities for Indigenous Australians through our Indigenous Employment Strategy (IES). Our goal is to build lasting career pathways by supporting skills development, confidence, and long-term employment.

Working closely with our Indigenous cultural advisor and local partners, we connect candidates with project roles and help them grow their potential for future success, within DEMEX or other employers.

Our efforts in these endeavours are guided by Martina Hazelbane, a Warai/Larrakia Traditional Owner and founder of 100% Aboriginal-owned JobTrail. Ms Hazelbane advises DEMEX on projects to support our IES. She helps identify suitable Aboriginal candidates, facilitates culturally sensitive communication, and supports skills development and training. Through this, we aim to build lasting career pathways for Aboriginal workers, both within DEMEX and beyond.

From the perspective of cultural awareness, we adopt the following measures to ensure our team is fluent in their cultural understanding:

Work with the DEMEX cultural advisor to identify and communicate with local traditional owners
Make provisions for cross-cultural training for our team, with this training facilitated by our cultural advisor in conjunction with a representative from the local traditional owners
Assess the training requirements for Indigenous workers and ensuring these are met during the course of the project
Identify opportunities for economic development and capacity building contributions to the local traditional owner community.

Drive About Workforce

We recognise that education and economic development are key to meaningful Indigenous engagement. Through the DriveAbout Workforce road safety program, we provide essential training in eight Indigenous languages. On each project, we also seek opportunities to partner with Indigenous-owned businesses for supply and subcontracting services.

In recognition of vehicle related incidents as a major killer in the workplace, in 2022 DEMEX formally committed to a work health and safety initiative to embed a culture of road safety into our organisation. Through our research into available training, we identified DriveAbout Workforce, an Australian road safety and road rules education program.

DriveAbout Workforce is an award-winning Australian road rules and road safety refresher, delivering road safety education. The training complements and supports existing driver education resources through its alignment to the National Road Safety Strategy 2021-30, and the Towards Zero and Fatal Five campaigns. It is scalable, cost effective, and suitable for culturally and linguistically diverse audiences.

Every DEMEX employee completed the training when the program was first implemented in 2022 and going forward, will complete an annual refresher. All new employees are required to complete the training as part of their onboarding induction, while employees who receive driving infringements in DEMEX vehicles are required to repeat modules relating to the infringement.
