The 1st Australian Tunnelling Company was one of the tunnelling companies of the Royal Australian Engineers during World War I. The tunnelling units were occupied in offensive and defensive mining involving the placing and maintaining of mines under enemy lines, as well as other underground work such as the construction of deep dugouts for troop accommodation, the digging of subways, saps (narrow trenches dug to approach enemy trenches), cable trenches, and underground chambers for signals and medical services.[1]
