The most favourable
areas, coal seams ranging in thickness of 60 metres through to 140 metres
with an easily removed layer of sand and clay averaging only 15 metres deep
were found. Boring at one point found the coal bed, only 27 metres
underground to be 270 metres thick!
In the fifty years to 1917, only 120 000 tonnes of brown coal was mined. In
the next 60 years, Victoria produced more than 300 million tonnes of coal.
By 1918, Victoria's population was 1.5

uninterrupted supply of electricity was essential. The Victorian Government
passed legislation to appoint Commissioners to regulate and investigate the
supply of electricity, particularly in the metropolitan Melbourne area,
where a shortage of power was imminent.
