Rural ecovillage harvests timber from nearby forest, with houses made from recycled materials

In the Fryers Forest, around 50 kilometers south of Bendigo, one group of residents isn’t feeling the rising cost of living as hard as most.

Hamish MacCallum is one of 30 people who live in a rural ecovillage, nestled in the forest in Fryerstown.

Standing in the kitchen of the house he built himself, he proudly explains the kitchen bench was a cypress tree that fell on a local farmer’s property during last year’s storms.

“[It’s about] taking a waste product, a fallen down tree, and turning it into something beautiful,” he says.

“The whole kitchen is recycled.

“All the cupboards and drawers, everything came from other kitchens that had been pulled out.”

There’s no heater inside, with the firewood stove in the kitchen emitting more than enough heat to warm the house.

“That’s only been running now for about half an hour,” Mr MacCallum says at 10am.

“It’s generating our hot water and providing us with an oven and a stovetop for cooking on as well.”

Mr MacCallum estimates his power bills are a third of the price of the average family’s electricity bills.

“I’m spending $150 on electricity for three months for the two households,” he says.

“It’s $100 a year for the gas bill.”

The bushfire management consultant and landscape designer put a huge amount of thought into designing and creating the house, with insulation and solar passive design a main priority.

“With a solar passive design, it’s using the sun to heat or cool the house by including or excluding it at particular times of year,” he says.

Timber from surrounding forest

Mr MacCallum has become an expert at reusing and recycling.

The house is made from 50 per cent recycled and reused materials, most of which were locally sourced.

On the verandah, two pieces of wooden ‘bush poles’ were eleven trees on this block of land.

Other pieces of wood were collected and stored from unexpected places.

“A lot of the timber came from a timber furniture maker who decided to give up his profession and sell it all on,” he says.

In the Fryers Forest eco-village, residents do forestry work, harvesting timber from the forest around them.

“Our expense is the time we spend collecting the wood from the forest, when we’ve done some tree thinning,” Mr MacCallum says.

“Always when we’re doing forestry, we get the highest value out of the timber as possible.

“Each season, we cut enough to provide the whole village with enough firewood to last them a season.

“The firewood [for the stove] is just a good solid day’s labor and a few days of forestry [work].”

Mr MacCallum refers to the concrete floor as a ‘thermal mass’ which holds the heat and keeps the house warm in winter and cool during summer.

In the middle of the house, a mud brick wall has the same function.

“It stores the cool over the summer and the heat over the winter and then releases it back into the household so you can wake up in the morning without any heating and the house will still be warm,” he says.

“The eaves that overhang the north side of the house, where most of the windows are, stop the sun coming into the house.”

Sharing food eliminates waste

Mr MacCallum’s family shares the house with another family, with two separate living quarters under the one roof.

Their efforts to live sustainably, with as little waste as possible, mean sharing a bathroom, laundry and food.

“A part of our strategy is to buy in bulk foods and to store in a big freezer,” he says.

“I might go hunting and harvest a lot of meat and then store the meat, the fat and the bones … make bone broth or render the fat down into lard or tallow and use that for cooking.”

He’s also committed to growing his own fruit and vegetables.

“80 per cent of our fruit and veg can come from [the garden] here,” he says.

But recently Mr MacCallum has been sourcing more of his produce from his local market, rather than his own garden.

“I help him [the seller] pack up and we get to take home a whole heap of fruit and vegetables,” he says.

“Sometimes that means that I’ve got to spend hours or preserving that produce.

“[Sometimes] that’s a few months’ worth of passata bottled and stored in an afternoon.”

Built to withstand bushfire

Mr MacCallum has spent years teaching others how to retrofit their houses for bushfire safety, so it was always going to be front of mind in designing and building his own eco-friendly house.

“I wanted to demonstrate how landscapes can reduce bushfire risk and be productive at the same time and beautiful at the same time as well,” he says.

Everything in his yard was planted for bushfire mitigation.

Fruit trees border his backyard, providing a heat shield against the fire front.

“The fruit tree hedge, also protected by the stone wall from radiant heat, acts as a heat and ember filter, as well as wind protection for the fruit and vegetable garden,” he says.

It may have taken years to build, and countless tutorials and tradesmen to help him learn new skills, but Mr MacCallum was never going to shy away from the challenge of living as sustainably and efficiently as possible.

“I wanted to take a piece of degraded land and turn it back into something beautiful and productive,” he says.

No new gas connections for ACT homes and businesses from 2023 under plan to phase out fossil fuels

Canberra homes and businesses will be unable to install a gas connection from next year under the ACT government’s plan to ditch fossil fuels by 2045.

Households are already leading the way, as natural gas prices convince them to switch to electricity to save money.

And Canberra’s new suburbs have already been designed without gas connections.

However, the government tabled legislation today to end all connections to new builds — including in older suburbs — as of January 1.

Chief Minister Andrew Barr said the transition — far ahead of the rest of the country’s schedule — would be “gradual and gentle.”

He said cutting off new gas connections was the only way to meet the ACT’s target of eliminating greenhouse-gas emissions.

“The days of cheap gas in Australia appear to be over,” Mr Barr said.

“Renewable electricity is now the cheapest and cleanest way to power our homes and businesses.”

About two-thirds of Canberra homes use natural gas — for heating, water systems or cooking — and the fuel accounts for about 20 per cent of the ACT’s emissions.

The ACT already buys more electricity from renewable sources than it uses: it reached its 100 per cent target three years ago.

Most remaining emissions come from transport, and the government revealed plans last month to phase out petrol and diesel engines.

Mr Barr said the government would help Canberrans to turn off their gas entirely by 2045.

“We know we need to make this transition in a responsible and considered manner — a way that provides certainty to households and businesses but also supports them during the transition,” he said.

Market forces already encouraging Canberrans to switch

Even before the Ukraine war worsened the global energy crisis, prices had been driving Canberrans to disconnect from mains gas.

In the two decades to 2020, gas costs for ACT households doubled after accounting for inflation.

They are expected to rise a further 19 per cent over the coming decade — about $220 a year more for a typical home.

Meanwhile, electricity prices are predicted to fall 3 per cent.

As a result of these pressures and environmental concerns, about 2 per cent of Canberra households each year have been cutting off their gas supply.

The government now expects that to increase to 2.5 per cent a year.

Its modeling also suggests that, without any policy interventions, market forces alone would reduce Canberra’s gas use by almost 60 per cent by 2045.

Change-over costs the biggest barrier: survey

The government says a range of incentives will help people and businesses change over.

These include the existing interest-free household loans of up to $15,000 to improve energy efficiency or switch to electricity.

Lower-value homes are also eligible for direct subsidies of up to $5,000.

Climate Change Minister Shane Rattenbury said disconnecting from mains gas was a longer-term goal, and there was no need to hurry, though it made sense to avoid the annual connection fees.

“As your current gas devices come to the end of their life, our advice to you is: make your next one electric,” he said.

“As you go to replace your hot water or heating system, don’t put another gas one in: choose an electric one today.

“It’s better for the environment and it’ll be better for your bank account — and we’ll help you make that transition over the coming years.”

A recent government survey found cost was the biggest barrier preventing Canberrans from switching to electricity.

At present, removing a gas meter and supply pipes costs about $800 per household.

The government said it would work with the Australian Energy Regulator to reduce or abolish that charge.

Mr Rattenbury said the ACT gas network would be switched off in 2045, but the government would not stop people from buying gas in LPG tanks if they wanted to.

“But I would say to those people: those new induction cooktops perform like gas, and the chefs we’ve talked to who’ve tried it love it.”
