Twelve years ago, after an international career in show business, three brothers from Melbourne came to Alice Springs with a dream about sustainable living and the determination to make it come true.
Today Ben, 39, Dan, 37 and Tom Falzon, 36, with the hands-on help of their dad Joey, are a long way down that journey – which isn't meant to have an end.
Their 40 hectare lease on a low hill of airport land at the end of Colonel Rose Drive has the grand name of Earth Sanctuary but its achievements are very much down to earth.
With solar cells and wind turbines, the brothers generate more power than they use.
They are connected to mains water but use it very sparingly, mostly relying on every drop of rain that falls onto the roofs their house, sheds and shelters, and collected in tanks with a combined capacity of 75,000 litres.
And they are building houses with linked together, Pine Gap style geodesic domes for just 15% of the cost of conventional homes.
And all that is put before up to 2000 school kids a year, from Alice Springs and around the nation, and several hundred "dinner and show" guests. ERWIN CHLANDA reports. Photos (from top): Dan with wind turbines. Tom dusting off solar panels. The metal domes.
