More than 20 years ago, Indigenous business trailblazer Jaynaya Winmar was "making myself smaller" in office spaces. A lot has changed since.

Winmar, a Ballardong Noongar woman from Quairading, founded Blakbone Sistahood in 2000.

The company prides itself on being a 'transformative initiative empowering Indigenous women in entrepreneurship, business, and leadership, fostering meaningful global connections among Indigenous professionals to strengthen economies and amplify the impact of collaborative efforts".

It provides support from the ground up, workshops, programs and room for networking.

Early on, that was something Ms Winmar found was difficult to enter, and "flipped the script".

"Just after I'd established Blakbone Sistahood, I was going into spaces that were corporate that didn't look like me, that didn't sound like me, and I was making myself smaller in those spaces," she told The Indigenous Business Review at the First Nations House global Indigenous Business Summit earlier this month.

"So once I discovered that I didn't need to make anyone feel comfortable with my presence," Ms Winmar threw out constraints on culture, including what she wore and how she presented herself.

"It was exposing them to Indigenous businesses, but also exposing them to feel comfortable with Indigenous people in that space," she said.

She also drew on culture for what proved an "effortless transition" to championing something familiar.

"So Blakbone Sistahood is because our Blak women are the backbone of our community. So that's kind of a play on words, but coming from a strong matriarchal line of the Noongar, it kind of just was an effortless transition into that space."

That work continues both closer to home and around the world.

A director on non-profit Indigenous business and entrepreneurship empowerment collective First Nations X, Ms Winmar is helping to 'start, grow and expand' the sector turning over $2 billion-plus a year, the group says.

Indigenous businesses globally "are an extension of family", she says.

"We all have the same cultural values of family, land, country, and what that circular economy looks like, and establish strong bonds with not just our business, but our culture and our community.

Ms Winmar recently spoke on a panel at the World Indigenous Business Forum in the US.

Delegations then came to Australia for First Nations House.

"So it's kind of that flow on effect that will be, we've created a space. The space looks like us, the space sounds like us. And we're exposing not just Indigenous businesses to each other and our global brothers and sisters that we've bought here, but also our west, West Tech (broader Western Australian business) family."

First Nations X co-chair and Nyiyaparli woman Jahna Cedar said First Nations House was about giving a "culturally safe space" to mix.

She said Australia is forced to navigate a space not underpinned by a Treaty, but also builds on 60,000 years of experience.

"We bring together the skills, the experience, our ancestral intelligence, in one space where we can network, share best practice, but also work together and collaborate with a lot of those from overseas that may face similar barriers and obstacles," Ms Cedar said at First Nations House.

"The vision for me is, how do we bring together mob in a safe space? How can we create introductions with international delegates with potential venture capitalists? How can we support our mob in creating what I'm passionate about - circular economies, where we can create our own businesses, but we also know we want to reinvest back into our communities.

"Of all countries in the Commonwealth, Australia is the only country that does not have a treaty with our government. So by having these international delegations, it means that we can learn from our international brothers and sisters on how they have got to where they've got to understand some of the advocacy that has supported them in getting there, we can bring it back to our country here and hopefully create that change for our mob but our future generations."

Ms Cedar is hopeful their next collective gathering will be at major arts and business festival South by Southwest (SXSW) in Texas, March.
