Our knowledge about the role of fly‐in fly‐out (FIFO) work‐related factors on the well‐being of workers across the FIFO work cycle is limited. This study examined the within‐person effects of job demand and control on psychological states and health behaviours. The study employed a daily diary design, with 23 FIFO workers in the Australian mining industry completing a daily diary survey for 28 consecutive days across on‐shift and off‐shift periods. Multilevel analyses showed FIFO workers experienced higher positive affect and enjoyed better sleep quality, but consumed more alcohol, during off‐shift days as compared to on‐shift days. Within‐person variability in daily demand (workload) was associated with higher anxious affect, whereas job control predicted lower anxious and depressed affects, higher positive affect, more alcohol consumption, and more physical activity. The within‐person effect of demand on anxious affect was moderated by job control such that those who generally had more control over their jobs had a smaller effect of demand on anxiety than those with less control. Results suggest potentially modifiable aspects of FIFO work—particularly job control—may help alleviate the impact of workload on poorer health behaviours and mood.
