massive sinkhole in the backyard of an elderly Aussie couple leads to an amazing discovery about the house

Shaft

The mayor put forth some facts about the shaft. He explained that one shaft was actually built in the same area but that was believed to be at least 40 meters far from the recently found hole. The misconception would have arisen because of lack of record keeping in early 1900. Not to forget it was dug sometime between 1903 and 1920.
