Who we are

Our Vision:
To increase accessibility to local, nutritious dairy in the Castlemaine region, practicing regenerative agriculture with the utmost respect for the animals involved.

The Humans

Growing up on a farm in Victoria’s north east, Tessa Sellar has long been passionate and heavily involved in promoting, farming and developing sustainable food systems to reconnect people with their food, farmers and landscapes.

Her partner, Oliver Holmgren, grew up in central Victoria immersed in a Permaculture way of life. Bringing a host of practical building and engineering skills, he is building much of the infrastructure.

The Cows

Working so closely with these ladies is a beautiful and humbling experience, each cow has a very individual personality. Getting to know them and build trust is one of the corner stones to this business. Running such a small herd also means that the individual characteristics of each cow’s milk is very noticeable in the flavour. Cow’s are named by family lines so in future years it’s easy to recognise who is related to who.


Named by her previous owner after Roberta Flack, she was our first cow and the start of the singer family line. Now in her 8th lactation she is about 11 years old. Berta is a mix breed, most likely a large percentage Holstein meaning she has a large boney build and definitely produces milk before looking after herself. Reaching 43ltrs a day at peak she has one massive udder which can leave her quite vulnerable. Her milk is similar to the Shorhorn in flavour. Berta is the most beautiful creature to behold; calm, affectionate with very strong mothering instincts. She was the matriarch but seems to be dominated by Joyce and Olive currently. Berta will come to her name when called.


Olive is a classic Jersey. Born and raised on the corner of Danns rd, daughter of the infertile Daisy, she will be the start of the Edible tree family line. Six years old and calving with her second calf Dec 2020. A very good milker who held condition after calving and held her milk volumn right through for 15 months, shes my dream jersey. A very rich yellow milk which sometimes you could mistake for straight cream. Olive is very cheeky, she loves to steal food and sneak into areas she shouldn’t. She’s known as Boomba as she can get quite fat. Currently Olive is dominated by Quartz and Iggy. Olive has a very husky jazz moo.


Joyce arrived August 2019 and has been a complete no fuse cow to work with, even if she is a grumpy old bag. Joyce is the beginning of the Buffy line. She’s a 10 year old Illawara dairy shorthorn who came from a certified organic dairy nearby. True to her breed she had an easy calving with Rupert and once she understood that her milking routine would now happen in a mobile parlour in the paddock she has been a dream to work with, often putting herself back in the stall after milking if I leave the gate open. Her breed combined with her age means her milk is very complex and savory. Joyce is due to calve Jan 2021. Joyce doesn’t moo, she yells.


Luna arrived from Guildford in 2019 as an 18 month pure A2 jersey heifer. Shortly after her arrival, we got her in calf to Satellite and she had Stella in October 2019 continuing the Astronomy line. Both Luna and Stella are a little mad, with a quirky energy, but very affectionate. When Luna arrived she’d had very little person contact and I couldn’t touch her, she now is the first cow to come to you for a scratch and comes to her name for milking. They both love a head and brisket scratch, are darker colouring in winter and have a very dainty build. Luna had milk fever after calving and serve edema which led to her losing the use of one quarter of her udder. She has made an incredible recovery and is my best producer, per quarter, now with a classic rich and creamy jersey milk. Luna will probably remain my most vulnerable cow around calving and is due in May 2021 to a Dairy Shorthorn bull to breed more resilience into her line. Stella will be the next to join the milkers and we intend to breed her mid 2021


Quartz also came from Guildford in 2019 as an 18 month old pure dairy shorthorn heifer. We chose the mineral line as her registered breeding line was Molly and we made a very loose connection to molybdenum. She had a straight forward calving with Onxy December 2019. Quartz wouldn’t let me near her when she arrived and prior to calving I didn’t know how I would ever tame this cow. Both her and Onxy have a very different energy to the rest, she often does her own thing, can be a little vague and get left behind a bit. She has a very gentle soft nature and loves a good butt scratch. At times she has come into milking by calling her name, currently she just looks up and decides not to, but is easily lead in. Her breed and age makes her milk very simple, clean and savory. Quartz can get picked on a lot however she dominates Olive so theirs always someone to steal from.


Iggy was the first calf I had on the property, born to Berta with a dairy shorthorn sire. A combination of following the singer line and my fathers nickname being IG. Iggy was a teenage tart who broke in with the neighbours bull, twice! Iggy has been my first experience of working with an animal I raised and it’s definitely paid off, although she has the attitude of a spoilt brat at times. As a human she is great to work with however she abuses her power within the herd, only being dominated by her mother. She maintained awesome condition after a very easy calving and has been a good milker, having clean, simple and savory milk.


Ginger arrived mid 2020, a five year old Certified Organic Illawara dairy shorthorn. Finally I have a roan shorthorn and she even has a love heart on her schnoz! Ginger is most definitely the sweetest cow to walk the earth but needs some lessons in holding her own. She went down hard with milk fever after having twins; Monte and Carlo, it was touch and go but she pulled through and has been a beautiful milker since, with a large volume of savory shorthorn milk. Ginger is the biscuit line.


Norma Jean was our adopted jersey calf who Berta raised along side Iggy. Marilyn Monroe was also adopted and while she did sing she mainly acted so Norma will split off into a film star line. She arrived as a 24hr old angel who has certainly learnt to hold her own. Norma calved with Doris in Oct 2020 and has been a dream to work with producing beautiful sweet milk and being very easy to train; not a single kick, poo or wee in the milking parlour!

The Farm

Sellar Farmhouse Creamery holds a lease at the foothills of Leanganook just outside of Harcourt, 9km from Castlemaine, Victoria. Harcourt was once the premier apple growing region in Australia and continues to have a large orchard industry, requiring the recently upgraded irrigation system.

Sitting about 380 metres above sea level with rolling granite hills, red gums and lightwoods dotting the landscape.

Our average rainfall sits around 560mm, mainly falling over the winter months. Turning the concrete granitic sands of summer into porridge in winter, with springs popping up everywhere as the ground-water follows the underground boulders.

Summer days mainly sit in the 30°s and can reach 45°C, with a winter average of 2°-12° occasionally dropping below 0° with frost.

Sellar Farmhouse Creamery farms on Dja Dja Wurrung country. We acknowledge that Aboriginal sovereignty on this land has not been ceded.

We pay our respects to the Dja Dja Wurrung people whose knowledge and care for this land has nourished and fed people for countless generations before us.

At the foothills of Leanganook we marvel and are reminded of the power and history of this country we farm.

The Harcourt Organic Farming Co-op

We’re lucky enough to be part of he Harcourt Organic Farming Co-op. A collaboration of diverse organic farmers in Central Victoria.

Katie and Hugh Finley have taken a new approach to succession planning for their second generation family farm, a 47 acre certified organic farm in Central Victoria now home to the co-op. Unlike the traditional farming co-op model; people farming the same product on different properties, using the combined energy to sell together, we’re doing things a little different. Different farming enterprises, working together on the same land to bring diversity and resilience to the land and our customers.

So far we are:

Gung Hoe Growers
Sas & Mel are the two hoes who make up Gung Hoe Growers. They grow real, dirty, food in Harcourt, Victoria. Gung Hoe Growers build soil, belly laughs, veggie porn and feed their local community through veggie boxes, a seasonal farm shop and various restaurants and cafes.

Tellurian Fruit Gardens
Orchardist, Ant, grows stone fruit, apples and pears. Selling through Community Supported Agriculture (CSA) shares, farmers’ markets, pick your own and farm shop. CSA Members can name their own price or organise a labour exchange for fruit.

Carr’s Organic Fruit Tree Nursery
Under the mentorship of Merv Carr who has been grafting and budding heritage fruit trees for over 50 years, sisters Katie and Liz are continuing the tradition. Carr’s Organic Fruit Tree Nursery grows a huge variety of quality heritage fruit trees for sale in winter as bare-rooted trees.

Grow Great Fruit
Hugh and Katie Finlay use their 20 years’ experience as organic fruit growers to teach others how to successfully grow organic fruit at home with their home-study program and one-on-one support.

And of course Sellar Farmhouse Creamery!

The Breeds

We run two main breeds in the herd which together create our delicious milk:


A small to average sized, classic dairy cow. Caramel colour often having a darker winter coat with black areas on face, neck, tail and feet. Black colour pigment: visible around eyes and nose. The Jersey cow has the highest butter fat content of the mainstream milking breeds in Australia. She is the best converter of feed into fat and her milk has a yellow appearance when on pasture. A very rich, simple and sweet flavour. Being a higher production cow they have a habit of producing milk first and then looking after themselves which can lead to higher risks of milk fever, weaker immune systems and struggling to keep weight on after calving.

Dairy Shorthorn

I have two types of Dairy Shorthorns in my herd; the classic English dairy shorthorn and the Illawara dairy shorthorn which is an Australian Breed created by breeding a small amount of Ayrshire and Devon blood into the classic shorthorn. The Illawara is considered to be a straight dairy breed as opposed to the traditional dual purpose Dairy Shorthorn. Both animals are known for their roan markings, they can range from pure white to pure red and everything in between. Red or white colour pigment around the eyes and nose. A medium size animal who is far beefier than a modern dairy cow; looking after herself at the same time as producing milk means they are known for easy calving, resilience, strong mothering instincts, fertility, grazing efficiency and calves which can be raised for meat. Their milk is white with a savory, complex flavour. While there are very few purebred herds of either left in Australia, they were previously one of the most popular breeds.
