1st Tunnelling Company
1st Australian Tunnelling Company
The 1st Australian Tunnelling Company went to Ypres and went on to relieve the Canadians at Hill 60.  Led by Captain Oliver Woodward they relieved the Canadians in November 1916, and maintained the mines throughout the winter and spring. At 03:10 on 7 June 1917, 19 mines filled with 450,000kg of explosives, were detonated underneath the German lines. Although two mines did not explode, the blasts created one of the largest pre-nuclear explosions in history. It was reportedly heard in London over 160km away and demolished a large part of the hill while killing more than 10,000 German soldiers.
- In the first week of November, the 1st Australian Tunnelling Company relieved the Canadians on the Hill 60 front.
- The two mines had been intended for immediate firing, but the change of policy meant that they would not be fired for some time to come. It was then decided to sink a vertical steel-lined shaft to replace the long incline, as the latter was more likely to be put out of action than a vertical one.
- Started by the Canadians just before leaving, the Berlin Shaft, as it was termed, 6 feet in diameter, was sunk to 94 feet deep by the Australians, and from the bottom a gallery was driven to the foot of the incline. Along this all the water was drained back to a large sump and pumped up the shaft by power. The new shaft effected a great saving in labour and also greatly improved the ventilation, which had continuously been bad, From this shaft also, a deep level defensive system was put in, and an offensive gallery pushed out towards a strong point called the Snout, but lack of time prevented its completion
By the end of World War One the 1st Australian Tunnelling Company had lost 5 officers and 62 men from their assigned strength of 1220. 166 had been wounded and 37 invalided.
