Fly-in fly-out is a method of employing people in remote areas by flying them temporarily to the work site instead of relocating employees and their families permanently. It is often abbreviated to FIFO when referring to employment status. This is common in large mining regions in Australia[1][2] and Canada.
Similar to the fly-in fly-out roster are the DIDO (drive-in drive-out), BIBO (bus-in bus-out) and SISO (ship-in ship-out) rosters.[3]
