Gas fields behave differently from mines
A coal mine concentrates people at one location. A coal seam gas field spreads them across hundreds of kilometres of wells, gathering lines, compression stations and processing facilities. The workforce is therefore distributed, road travel within the field is a significant part of the working day, and the aviation question becomes which gateway minimises total ground time rather than which strip is closest to a single pit.
That distribution also means the workforce mix leans heavily toward contractors and specialists, drilling crews, well services, compression and processing technicians, construction and commissioning teams. Those crews mobilise and demobilise more often than a permanent mine workforce, which produces more frequent, more variable movements.
Proximity to the coast is the third factor. The Surat Basin is closer to Brisbane and Toowoomba than the Bowen Basin, which makes road transport a genuine competitor to flying for some crews and changes where charter earns its place: usually on longer catchments, tight mobilisation windows and turnaround peaks.
