As foreboding as a mangrove swamp, the windswept valley’s icy blasts warned Christine and John Black, this place wasn’t for the light hearted.
Nine hundred metres above sea level, and 170 kilometres north of Canberra, massive frosts, heavy snow dumps and relentless wind tested their resolve. Now, after 18 years of living off-grid north of the bluestone village of Taralga, in an L-shaped home recycled from Sydney that arrived in three sections, the Blacks are expanding their home and businesses.
They named their 70-acre block Mangrove Farm to embrace nature’s way of generating new life in tough climates. They produce so much power they dump excess in summer.
Instead of paying for power poles to join the grid they invested in solar and wind. Outlay and upgrades to the 24, 800-watt solar panels and 1-kilowatt wind turbine and batteries over the 18 years totals $60,000.
“A lot of people say how long will it take you to pay it off?’’ Mrs Black said. “We don’t care what it takes. We are looking at it from the point that this is our decision, instead of a pay back thing where everyone wants to get their dollars back.’’
Mr Black adds, “The trick is not how much power you can produce, we can always produce enough, it is how well you can store it. It’s like rainfall, if you can store what you have got coming down it helps in the leaner times.’’
Developers in Canberra’s newest suburbs are tempting people with off-grid energy options, but the Blacks motivation was simply powering a three-bedroom home, office, three computers including one linked to a weather station, two freezers and two fridges.
They are going to treble their home’s size, grow and process truffles and continue expanding their consultancies and berry ventures. More than 400 trees in three varieties of oak and hazelnut inoculated with truffle spore were sown three years ago.
A workplace safety and traffic management consultant, Mr Black was involved in construction of Goulburn’s notorious Supermax prison, came face to face with backpack murder Ivan Milat -“we called him Uncle Ivan’’ – and recycled apple trees no longer wanted at the jail.
A registered nurse Mrs Black works six shifts a fortnight in Goulburn and capitalises on Mangrove Farm’s acidic, red basalt soil by growing raspberries, blackberries, boysenberries and red currants.
“The cold is ideal for berries, they are planted on the southern side of the slope of the valley, it keeps the roots cooler,’’ she said. Her mother Helen Jamieson sells out of the jam at a little shop in Moruya as quickly as she makes it.
Mangrove Farm’s winters punish as Mr Black found when pneumonia struck. They have been rewarded for the berry cover and water they have added, with red-browed fire tail finches that flit through fence netting, and regular visits from European goldfinch, superb blue wrens, bowerbirds, tree creepers and king parrots.
