Sisters Mika Koelma and Zoe Fehlberg are living proof that the world needs women in manufacturing.
The Hunter pair are the brainchild behind Hey Zomi, creators of Australia’s first reusable menstrual disc, launched in January 2023.
Just 10 months after their business began, the duo picked up the Hunter Manufacturing Award for excellence in marketing, an accolade they say became a turning point.
Mika and Zoe are just two of what is becoming an influx of women in Hunter manufacturing.
They now fill a variety of roles within the sector, testament to its evolution in the region and the ingenuity of its proponents.
For Hey Zomi, the HMA represented an opportunity to take stock of their business plan.
The co-founding sisters have since realigned their priorities and made multiple changes and experienced significant growth.

“It’s really cool to look back and see how far we’ve come,” Ms Koelma says.
“This manufacturing journey is addictive. It is amazing to have manufactured this product and see what we are capable of. We are already asking ourselves what other things do we want to innovate? And what other problems can we solve?
“And, that’s a really beautiful part of being able to grow as a start-up.”
Kari Armitage knows the feeling.
She took over from her father as managing director of Quarry Mining 18 years ago.
The company has been providing a wide range of quality bespoke products, service, and support to the construction and mining industry for 30 years.
“Our sales team are all former underground coalminers,” Ms Armitage says.
“They still go underground, and they know what it is that mines need to make their lives easier. We will manufacture it for them. We make a lot of bespoke stuff and there’s a lot of tweaking involved in those bespoke jobs.”
Ms Armitage studied civil engineering and her first job was with WorleyParsons, the Australian engineering professional services company.
Her boss was a design engineer consultant.
“When I came to Quarry Mining, I think I brought a consultant-style approach to a manufacturing business,” she says.
“In hindsight it was a lucky thing because Quarry Mining has learnt to listen to the customer, consult them, find out what their problem is, and then manufacture something to provide a solution rather than offer a widget off the shelf.
“That has been ultimately a competitive advantage or point of difference from traditional manufacturers where they just offer what they have. So, it’s been a great benefit to have that background.”
As for being a woman in a traditionally male-dominated sector, Ms Armitage says it is not something of which she is conscious.
“I come across some other women in the mines,” she says, “but not in manufacturing.
“I do remember attending an executive connection event. It was great. There were all these CEOs in the room, and we just learnt from each other. We talked about the challenges, problems, and stuff you go through daily when you’re CEO of an SME.
“At the end of the day, the organiser said to me something like, ‘Oh you know the guys thought you were really good, and they didn’t mind having you there at all’. And I hadn’t even realised I was the only girl in the room. It hadn’t occurred to me because I’m so used to it.”

Rachel Jameson has worked at Deeps Engineering for seven years, but the manufacturing industry has been her life.
Deeps is her dad’s company.
It specialises in custom injection moulding and spent years not having its own proprietary line and making things for other people.
This year, Deeps purchased two other businesses to provide it with a proprietary line.
“Obviously, custom mouldings is not going to last forever, particularly with many people taking their work overseas where it is cheaper,” Ms Jameson says.
We saw the opportunity to buy these two businesses to give ourselves a proprietary line to make sure Deeps goes further than what we were originally doing for 30 years.”
Ms Jameson was three when her father opened his own business, and she grew up around the plastics moulding.
“I remember as a kid it was very much a male-dominated industry, but then as I got older and through my teens, I saw more women coming through working in the factory. It was really good seeing that. Now we have as many women working here as men.”
Ms Jameson knows they are as effective as their male counterparts, and she often goes onto the floor to help dissect the moulding machines and assist where she can.
“Girls can get in there and get dirty as well,” she says.
Deeps shares a similar HMA experience to Hey Zomi.
“We’ve been in business coming up to 33 years this year and it wasn’t until 2021 that we entered HMA,” she says.
“It was the first-ever awards we entered, and that was at my initiative. No one at Deeps really had the time to enter awards and get our name out there. So, I took that on.
“We entered the HMA and it’s great to go to the event and meet other people within the industry. It gets our name out there. We spent 30 years of people not knowing we even existed. Much of our business came from word of mouth.
“Since entering the awards in 2021, we have made connections with other businesses in the Hunter. It’s a good opportunity to meet other businesses where we can help them, or they can help us.”
HMA encourages all manufacturers in the Hunter region to enter the 2024 awards.
Applications for the 2024 Hunter Manufacturing Awards close on 30 August.
