The Farm at Mirrim Wurnit · Macedon Ranges, Victoria
A 100-acre regenerative farm, off the grid, on Wurundjeri country — Mirrim Wurnit, Deep Creek, where people, animals and country thrive together.
The Farm
Mirrim Wurnit — the name given to us by the Traditional Owners for Deep Creek in the Woi wurrung language — winds through our 100-acre farm in the Macedon Ranges. We came here with a simple intention: to live well, to give more than we take, and to leave this land healthier than we found it.
Our family and guests live here entirely off the grid — solar power, rainwater, local firewood and the creek for drawing water for livestock (plus Starlink, a necessary evil). Our chickens provide eggs daily, we grow vegetables for our own table, tend a small but growing herd of cattle and a flock of sheep, and share our paddocks with alpacas, our lovely dogs and Percy the Pig!
We think of ourselves not as owners but as custodians — temporarily responsible for a piece of country with its own deep history, its own intelligence, its own needs.
Peter & Kate Munns
This is Wurundjeri country — Mirrim Wurnit, Deep Creek, has been cared for by the Wurundjeri Woi Wurrung people for tens of thousands of years. We approach our time here with humility, learning from country, returning what we can, and carrying a responsibility that is bigger than ourselves.
We follow holistic, regenerative grazing principles — moving livestock through paddocks in a planned pattern that mimics the natural movement of wild herds. Resting pastures between grazes builds topsoil, sequesters carbon, and restores the deep-rooted grasses that once covered this country.
Up to 30% of our property is being permanently set aside for revegetation — planting thousands of native trees and understorey shrubs endemic to the Macedon Ranges. These areas will become habitat corridors, connecting remnant bush and giving wildlife room to move and thrive. Our Land Management Plan identifies several species of conservation significance in the area — Grey-crowned Babbler, Bush Stone-curlew, Long-nosed Bandicoot, Squirrel Glider and Brush-tailed Phascogale — and the revegetation is designed to support their return.
Country & Culture
Mirrim Wurnit — Deep Creek — sits on the traditional Country of the Wurundjeri Woi Wurrung people, part of the broader Kulin Nation, whose connection to this landscape spans at least 26,000 years. Colonisation disrupted and destroyed much of that living culture — but what survives tells us the eastern Macedon Ranges are rich in cultural significance: from the sacred heights of Mount Macedon (Geboor) and the ceremonial site of Hanging Rock (Ngannelong), to the Mount William stone axe quarry (Wil-im-ee Moor-ring) — an important source of greenstone axes traded across south-east Australia for thousands of years. The stone was quarried and roughed out here, then carried to Mount Macedon — just 29 kilometres away — where the nearest grinding grooves have been found, the same greenstone confirmed by analysis. A trade route that ran through this country. The Wurundjeri Woi Wurrung and their descendants remain active in this country today. We sit with that history lightly and with respect.
* The figure of 26,000 years reflects the oldest archaeological evidence found and dated to this point. It is likely that Indigenous occupation of this landscape extends much further back in time.
When Governor Bourke ascended Mount Macedon in 1837, local Aboriginal people told him the traditional name was Gee Burgh (Geboor). The mountain was significant hunting grounds and held deep cultural meaning for the Wurundjeri and surrounding peoples. The nearest grinding grooves for Mount William greenstone axes have been found here — making Geboor a key stop on an ancient trade route that passed through this country.
Located near the traditional boundaries between the three Aboriginal groups, Hanging Rock was a sacred place used for ceremonies, mediations and initiations for at least 26,000 years. Archaeological evidence shows stone tools dating back at least 10,000 years, with stones sourced from considerable distances — evidence of a vast social and trade network.
Perhaps the most significant site in the eastern Macedon Ranges. Wil-im-ee moor-ring means "axe place" in Woiwurrung. This greenstone quarry — comprising hundreds of mining pits — was the source of ground-edge axe heads traded across south-eastern Australia. Stone was quarried and roughed out here, then carried 29 kilometres to Mount Macedon (Geboor) to be ground and polished. Wurundjeri leader William Barak described how specific custodians controlled access, with neighbouring peoples sending messengers bearing opossum skin covers, weapons and ornaments to trade for stone. In 2012 land title was handed back to Kulin elders. It is now listed on the National Heritage List.
A smoking ceremony — tanderrum in the language of the Kulin Nation — is one of the most significant cultural practices of the Wurundjeri and neighbouring peoples. Native plants, particularly eucalyptus and other aromatic species, are burned to create a cleansing, healing smoke that welcomes visitors to Country, marks significant transitions and gatherings, and connects those present with the spiritual life of the land.
A smoking ceremony is held before the start of every Back Paddock Ultra — a moment that grounds the event in country, and one that runners and spectators alike have come to deeply value.
How We Graze
Regenerative grazing begins with a single observation that changes everything: livestock, managed well, are not a problem for the land — they are the solution. The key is movement. Animals that graze one area and move on, allowing long rest periods before returning, mimic the behaviour of the wild herds that built the world's great grasslands over millions of years.
At The Farm at Mirrim Wurnit, we divide our 60 acres of pasture into multiple paddocks using a combination of semi-permanent and temporary electric fencing, rotating our Dexter/Lowline cattle and Aussie White sheep through them on a planned schedule. Our chickens move with the sheep — following behind to scratch through the manure, break parasite cycles, and forage the insects that the sheep stir up. Our alpacas work as guardian animals for both the flock and the chickens, keeping a watchful eye out for foxes and other predators. Each paddock rests for months between grazing events. The grass recovers fully, roots deepen, organic matter builds, and the soil comes alive.
The results show up in the ground: improved water infiltration, more diverse pasture species, reduced erosion, and a steady increase in the sponge-like quality of the soil that makes this landscape more resilient to both drought and flood — exactly what country in the Macedon Ranges needs.
Thinkers & practitioners who have shaped our approach
Savory's Holistic Planned Grazing framework — developed over decades of field observation across Africa and the Americas — demonstrated that large herds of animals, properly managed, can reverse desertification and rebuild grassland soils. His insight that the land needs animal impact, not less of it, is the foundation of everything we do here. savory.global →
The New South Wales farmer who developed Natural Sequence Farming — the practice that underpins our whole approach to land and water at Mirrim Wurnit. Working against the grain of conventional agriculture, Andrews restored degraded catchments by slowing water, rebuilding organic matter and letting landscapes rehydrate themselves. His two books, Back from the Brink and Beyond the Brink, are essential reading for anyone serious about land restoration in the Australian context.
Massy's landmark book Call of the Reed Warbler brought the regenerative agriculture movement to an Australian audience, documenting farmers across the country who had transformed their land through holistic thinking. As both a farmer and a scholar, he gave Australian regenerative agriculture its own voice — and its own deep connection to country. Watch him talk →

Effective rotational grazing depends on being able to move animals quickly and reliably. We use a combination of semi-permanent and temporary electric fencing across our paddocks, giving us the flexibility to adjust cell sizes and rotation times as conditions change.
Our Animals
How We Farm
Natural Sequence Farming (NSF) is a framework for understanding how the landscape functioned before human interference — and for actively restoring those functions. It begins with a simple but profound observation: that plants manage water, and water builds everything. Together, they are the engineers of a healthy landscape.
At The Farm at Mirrim Wurnit, we are putting NSF principles into practice on the ground. We are currently installing contour banks across the property — earthworks that slow the movement of water down slope, spreading it across the land rather than allowing it to race off into the creek. This rehydrates the soil, reduces erosion, lifts the water table, and begins to rebuild the deep landscape function that once made country like this extraordinarily productive.
Combined with our revegetation work, holistic grazing and riparian fencing along Mirrim Wurnit, the contours are part of a long-term commitment to landscape restoration — working with the patterns of country rather than against them.
The Five Pillars of Natural Sequence Farming — hover to explore
Contour banks, swales and retained vegetation slow water moving across and through the landscape — above and below ground — giving it time to sink in rather than run away.
Every plant has a role in landscape succession. Nature determines what is needed. We listen before we pull — understanding that so-called weeds are often responding to a landscape in need.
Sensitive areas — creek banks, wetlands, newly planted zones — are fenced and rested. Animals are used as tools where beneficial and excluded where the land needs to heal.
Wetlands and floodplains naturally filter water and process fertility before it leaves the landscape. We are working to reinstate these areas along Mirrim Wurnit so nutrients cycle back through the system.
Fertility that accumulates in lower areas must return upslope to close the loop. Grazing management, composting and strategic plantings all help cycle nutrients back up the landscape system.
"One of the best things I've learnt is to manage for what you want, not what you don't want. I apply this to my thinking about weeds — the main one here is Chilean Needle Grass — so rather than spraying poisons and doing mechanical removal, we are letting the pasture revert to more palatable grasses by managing grazing and improving hydrology."
— Peter Munns

We are currently reviewing the use of indigenous cultural burning to improve and manage our grasslands, fostering the growth of native species. Cultural burning — practised by First Nations peoples across Australia for tens of thousands of years — uses low-intensity, carefully managed fire to rejuvenate country, reduce fuel loads, and encourage the regeneration of native grasses and plants. As we learn more, we hope to integrate these practices alongside our regenerative grazing and Natural Sequence Farming approach.
Land Use
Not all land should be farmed. We're actively transitioning up to 30 acres — 30% of the property — from farmland into permanent native habitat. The remaining 70 acres is managed holistically: grazed, rested, monitored and adjusted season by season. The property straddles the boundary of two bioregions — the Central Victorian Uplands and the Victorian Volcanic Plain — which accounts for much of the landscape diversity here, from the volcanic rocky escarpments on the hilltops to the rich creek flats below.
Alongside the revegetation work, the banks of Deep Creek itself have been carefully fenced and planted to reduce erosion and shade the water, encouraging the return of platypus, fish and aquatic invertebrates. Access to the paddocks on the far side of the creek will eventually require a ford crossing — designed and built in collaboration with Melbourne Water — a practical reminder that farming around a culturally and ecologically sensitive waterway takes patience and care. Our work on Deep Creek sits within a larger vision for the landscape — we are supporting and consulting with the Biolinks Alliance, whose Deep Creek Biolink project aims to restore ecological connectivity along the creek system and beyond. Although the farm is currently outside the boundary of their project area, our revegetation and corridor-building share the same goals.
"We are the current custodians — the land was here long before us, and will be here long after."— Kate Munns
Revegetation & Biodiversity
Our revegetation work — planting thousands of indigenous trees, shrubs and grasses across The Farm at Mirrim Wurnit — is made possible through partnerships with four outstanding organisations.
Our approach
Every plant we put in the ground is chosen to match the local ecosystem — specifically the three Ecological Vegetation Classes (EVCs) mapped on this property: Plains Grassy Woodland, Stream Bank Shrubland and Herb-rich Foothill Forest. We're not planting generic native species; we're rebuilding the precise plant communities that belong here, with the insects, birds and animals that depend on them. The deep root systems of established native vegetation also play a vital practical role — intercepting and absorbing agricultural runoff, including animal manure, before it reaches Deep Creek and the broader waterway system.
Succession planting
We plant in stages, working with the logic of ecological succession. First come the fast-growing pioneer species — acacias and other native shrubs that establish quickly, fix nitrogen from the air and create shelter for what follows. Into that framework we plant native grasses and forbs. Over time, as conditions improve, we introduce the canopy trees and the mid and understorey species that make up a mature, self-sustaining woodland — giving back to the land something closer to what was here before.
Better farming, not less
Committing 30% of the property to biodiversity isn't a concession — it actively improves the productivity of the remaining 70%. Shelterbelts and windbreaks reduce stock stress and pasture desiccation. Native vegetation on slopes and creek margins holds soil in place and keeps water in the landscape longer. Increased insect diversity supports pollination and natural pest control. Deep-rooted native plantings draw up and cycle nutrients that shallow-rooted pasture grasses can't reach. A more biodiverse farm is a more resilient farm — better able to handle drought, flood and the pressures of a changing climate in the Macedon Ranges.
Melbourne Water manages the rivers, creeks and waterways of the Port Phillip and Westernport region, including Mirrim Wurnit. Their Stream Frontage Management program supports landholders like us to fence, revegetate and restore the creek banks that protect water quality for all Melburnians.

landcareaustralia.org.au →The Home
The house at The Farm at Mirrim Wurnit is not a typical Australian farmhouse — and that is very much the point. Designed by Clinton Murray Architects, the brief was to create a home that could hold its own against the drama of the landscape: the creek to the west, the escarpment rising beyond it, the falcons nesting in the rock face, and a valley that funnels bitter winds from north and south in winter and bakes in summer.
The response was to dig the house into the hill — building protective walls from insulated concrete to buffer the extremes — while softening the interior with timber, colour and fine detail. From the outside it reads as simple, almost brutish in the paddock. Inside it is warm and considered. It sits a respectful distance from the creek, its form mirroring the drama of the escarpment opposite.
Off the grid from the outset — solar, rainwater, no mains connection — the house was designed to live within what the site provides. The valley's climate demanded it.

How We Live
No mains connection, no grid dependency — our entire property runs on sunlight stored in batteries. The system is sized for a working farm, not just a house.
Drinking and household water is collected from our roof and stored in large tanks — up to 120,000 litres behind the garage and 30,000 litres under the house. Deep Creek provides water for the animals and irrigation.
A dedicated solar array by the creek powers a pump that lifts water up to a header tank. Gravity does the rest — sending water through underground pipes to wherever the animals need it across the property. Three fixed concrete troughs serve our main grazing areas, but the backbone of our system is a network of Kiwitech movable troughs that attach to taps along the buried pipes — so water follows the animals as they move through the rotational grazing system, rather than the other way around.
Waste is something we are very conscious of. As far as possible we try to compost or recycle on property. We have our own septic solution which feeds in to part of the paddocks, and of course animal manure and urine already directly feeds pasture. We try to use fallen branches for firewood as much as possible and in time will plant our own woodlot. Then it just comes down to aiming for as little else leaving the property as possible. Hay is another thing — we may buy it in occasionally but we never send fertility off-farm in that form.

Annual Event · Est. 2019
The Mirrim Wurnit Back Paddock Ultra holds a special place in Australian running history: we ran our first event in 2019, making this Australia's original backyard ultra. Each autumn since, runners have returned to The Farm at Mirrim Wurnit to test themselves on our paddocks, creek crossings and bush tracks in the Macedon Ranges.
The backyard ultra format is beautifully brutal: one 6.7km lap on the hour, every hour, until only one runner remains. No set finish line. No fixed distance. Just you, the land, and the question of how many times you can loop through the back paddocks before your legs or your will gives out first.
We are proud members of AUTRA — the Australian Trail & Ultra Running Association, the peak body for ultramarathon and trail running in Australia.
In 2022 we were honoured to welcome Lazarus Lake — Gary Cantrell, the Tennessee farmer who invented the backyard ultra format and created the legendary Barkley Marathons — to The Farm at Mirrim Wurnit. His visit meant a great deal to us and to our running community.
