Safety Matters - # 11 - Drug and Alcohol Use in Australian Manufacturing: A Timber Frame and Truss Industry Perspective
28th July 2026
By Simon Williamson - Chair, FTMA Frame & Truss National Safety Council
Australian manufacturing has never been risk-free, but the timber frame and truss sector carries a particular combination of hazards that makes drug and alcohol use a serious workplace safety issue rather than an abstract policy concern. Between docking saws, automated nail plate presses, truss jigs, cranes, forklifts, and constant manual handling, a moment of impaired judgement can result in serious consequences.
Understanding why our industry is exposed, and what can realistically be done about it, matters to every frame and truss plant manager, supervisor, and worker in the country.
The National Drug Strategy Household Survey has independently identified manufacturing as one of the industries with the highest rates of long-term high-risk alcohol consumption in Australia, a pattern that has held steady across two decades of data collection.
Workers in trade occupations, which include qualified positions found in frame and truss production, such as wood machinists, report the highest rate of illicit drug use of any occupational group in Australia, at around 1 in 4.
The Alcohol and Drug Foundation (ADF) puts the scale of the problem in sharp context. Among Australian workers who used alcohol or illicit drugs in the past 12 months, 1 in 37 reported working while under the influence of alcohol, and 1 in 9 reported working while under the influence of illicit drugs such as methamphetamine, cannabis or opioids.
The ADF also links use directly to absenteeism as roughly 1 in 22 workers missed at least a day of work in the preceding three months because of alcohol or drug use.
Importantly, the ADF also notes about a 30% of Australian workers report being personally affected by a co-worker’s alcohol or drug use, through involvement in an accident or near miss, reduced ability to do their own job safely or having to cover a co-worker’s days off.
The financial and human cost is substantial. Alcohol and other drugs contribute to around 11% of workplace accidents and injuries nationally, with alcohol-related time off costing Australian workplaces approximately $3.6 billion a year, and illicit drug use adding a further $1.5 billion annually in workplace costs.
On a frame or truss production line, running saws, presses, and overhead cranes and where tasks are often sequential and interdependent, one impaired worker can put an entire crew at risk of catastrophic harm.
There are a number of features of the timber frame and truss sector that increase the risk profile beyond that of generic manufacturing. These include
Machinery interaction is constant, not occasional. Unlike some manufacturing roles where operators monitor automated lines from a distance, frame and truss production typically involves hands-on interaction with saws, presses, and cranes throughout a shift.
Physical strain drives self-medication. Repetitive lifting of timber and maneuvering frames and trusses can be physically taxing, and chronic pain from this kind of work is a recognised driver of both problematic alcohol use and, in some cases, misuse of prescription or non-prescribed painkillers to get through a shift.
Piece-rate and production-target cultures. Many plants run on production targets tied to builder deadlines. This can create pressure to keep working through fatigue or discomfort, and can also foster an after-hours drinking culture as a release valve
Workforce demographics. Younger, male-dominated crews are statistically more likely to normalise risky drinking and casual drug use as part of workplace culture.
The ADF is also explicit that once-off or random drug testing alone has been shown to be less effective than a comprehensive, well-communicated policy and reinforcing that testing should support a broader strategy rather than substitute for one.
To mitigate these risks there needs to be a proactive approach to alcohol and illicit drug use in the workplace with clear policies, robust testing programs coupled with education and awareness. Alcohol and other drug policies should be written in plain language, be implemented with worker consultation and consistently enforced.
Managers and supervisors should receive training to help them to recognise signs of impairment early, rather than in the aftermath once an incident has occurred.
Workers should be provided with access to genuine support, not just punitive consequences. Only around 1 in 6 workers currently report having access to alcohol & other drugs education, leaving a wide gap for referral pathways to counselling or treatment.
Employers should where practical, address the physical and cultural drivers, including manual handling improvements to reduce chronic pain, realistic production scheduling, and shifting site culture away from drinking as the default social outlet.
For frame and truss operations, drug and alcohol use isn’t a peripheral HR issue, it sits directly alongside machine guarding and manual handling as a core safety risk, shaped by the specific physical demands, culture, and workforce profile of the industry. Plants that treat drug and alcohol management as seriously as they treat saw safety, backed by clear policy, trained supervisors, and real support pathways, are the ones most likely to keep both their people safe and their production targets intact.
