FIFO: substance use in fly-in fly-out culture

The fly-in fly-out model of employment creates a set of conditions that are, from a behavioural science perspective, fairly predictable in their effects on substance use. Extended periods of isolation, high-demand physical or managerial work, peer cultures with particular norms around toughness and stoicism, followed by compressed blocks of free time with significant money and social pressure to make the most of it.

This is not a moral commentary on FIFO workers or on the resources sector. It's a structural observation: the FIFO schedule creates specific risk conditions, and understanding them is more useful than either dismissing the concern or catastrophising it.

What the research shows

The research on FIFO work and substance use is reasonably consistent, though the Australian evidence base is more developed for mental health impacts than specifically for substance use patterns.

The FIFO mental health inquiry by the Education and Health Standing Committee of the Western Australian Parliament found elevated rates of depression, anxiety, and substance use in FIFO populations relative to comparable non-FIFO workforces. The University of Queensland's FIFO Research Centre has documented the specific mental health toll of roster-based isolation, with particular emphasis on relationship strain, social disconnection, and the difficulty of re-integrating into family life during R&R periods.

Australian National Health and Medical Research Council data from broader workforce studies consistently finds shift work and irregular hours as independent risk factors for alcohol misuse , a finding that applies broadly to FIFO conditions.

The specific pattern that emerges from the FIFO context is not necessarily daily or heavy drinking during the roster , many mine sites are dry, and the occupational safety requirements of the work enforce some degree of sobriety. The pattern is more often binge concentration: a week or two of compressed, intensive drinking and sometimes drug use during R&R, followed by a return to the site.

The structure of the pattern

Understanding why the binge concentration pattern develops helps in examining whether it's operating in your own behaviour.

The site as pressure cooker. High-demand work, limited privacy, significant responsibility, and social environments with limited options for decompression create sustained psychological load. The tools for managing this load in a normal residential context , time alone, varied social contact, access to recreational activities, the texture of ordinary domestic life , are largely unavailable.

R&R as decompression. The transition home is the first real decompression opportunity in weeks. For many FIFO workers, drinking is the most readily available and socially endorsed tool for that decompression , and the intensity of the built-up need produces proportionally intensive use.

Relationship and family pressure. R&R periods carry expectations from family that can create their own pressure , the absent partner returning, the parent trying to re-establish their role in a household that has functioned without them. Alcohol facilitates the social lubrication of these re-entries and also provides escape when they're difficult.

The money factor. FIFO workers are typically well-paid. The financial constraint that moderates substance use in many people's lives is reduced or absent. This is not a moral observation , it's simply that the cost of a night's drinking that would deter many people is not a deterrent at FIFO wage levels.

Normalisation within peer culture. Drinking culture in many FIFO cohorts is significant. The social norm is that R&R involves drinking, that the week at home includes substantial alcohol, and that this is earned and appropriate. This normalisation makes it structurally harder to examine the pattern clearly, because the comparison reference group all share the same behaviour.

Mental health and the roster cycle

The research on FIFO mental health is more developed than the substance use literature, and the two are connected. Isolation and loneliness on site are significant predictors of poor mental health outcomes. The psychological model underlying FIFO substance use often involves alcohol and drugs performing a genuine function , managing boredom, loneliness, the absence of normal social and recreational life during site rotations, and the difficulty of the R&R transitions.

The functional use framing is important here for the same reason it matters in any substance use context: habits driven by genuine need are harder to change than habits of convenience, because removing the substance removes the function it was performing without replacing it. Understanding what the use is doing is more useful than simply noting that it's occurring.

What tracking reveals

The roster structure actually makes self-monitoring particularly informative. The use pattern is inherently cyclical , tied to a schedule , and comparing mood, sleep quality, and functioning across the site and R&R phases gives a picture that would take months to accumulate in a standard residential context.

Many FIFO workers who track their substance use across a full roster cycle find a few things they didn't expect. The drinking during R&R is often more than they estimated. The mood trajectory on return to site , which they had attributed to disliking the job or relationship stress , correlates with the tail end of the previous R&R's drinking rather than the site conditions themselves. Sleep quality at site, despite the enforced sobriety, is sometimes better than sleep quality at home, where the R&R drinking has disrupted it.

This information doesn't require a decision. It just requires looking.
