In July 1949, construction began on the Snowy Mountains Hydro-Electric Scheme, Australia's largest ever project. At that time, Australia had not even one steel tower transmission line, and the existing timber ones, distributing power over a limited part of the country, were periodically burnt down by summer bushfires.
During the ensuring fourty years, a network of steel tower transmission lines would be built, to link even the remotest outpost to the national grid.
