Cave dwellers of Oz
The tiny outback town of White Cliffs in far north-west New South Wales can now claim a place in Australia’s engineering history, alongside the Sydney Harbour Bridge and the Snowy Hydro scheme.
The opal mining town, where most of the 200 residents live in underground homes, was the first in Australia to be powered entirely by solar energy, and is still a fully off-grid community.
The solar plant is now closed but it has earned a national award that will see it preserved as a piece of alternative energy heritage.
