For the past two years, the 13-year-old has run an online store selling Indigenous merchandise with the help of her dad - founder of Darkies Design and 2018 ACT Australian of the Year Dion Devow.

Now the Daramalan College student will share what she's learnt with other aspiring "kidpreneurs" around the country through the Academy for Enterprising Girls.

The academy - set to launch on Friday, which is also the International Day of the Girl - will have online modules where girls aged 10 to 18 can learn about design, coding and business development.

It also features videos from young female entrepreneurs - including Tea - and some of Australia's most successful businesswomen, like Mia Freedman and Helen McCabe.

The academy is funded through the federal government's $3.6 million Future Female Entrepreneurs Program.

Director Annie O'Rourke said the academy would "appeal to girls' natural talent for problem solving".

"We know many girls struggle to see themselves as CEOs, entrepreneurs, engineers and IT specialists," Ms O'Rourke said.

"It's about ... showing them the possibilities that are open to them."

Tea has big dreams for her label, Tea and Belle. Founded with her friend Belle, she hopes to open a permanent shopfront so more people will encounter her products.

Asked what advice she would give a fellow kidpreneur, she said: "Just keep doing what you're doing. A lot of people might not agree with it but just ignore them and give it a go."

Tea's mum Danielle Devow, who also helps with the business, said it was important for parents to believe in their children.

"I think having the support of a parent makes a huge difference to a kid, when you let them live out their dreams and have a go," Mrs Devow said.

The academy will also encourage girls to pursue careers in science, technology, engineering and maths (STEM).

"Currently boys outnumber girls three to one in Year 12 physics, and almost two to one in advanced mathematics," Ms O'Rourke said.

"On top of this, only 16 per cent of the STEM workforce is women.

"These sorts of statistics tell us that we need to improve the way we market these kinds of career pathways to girls. Particularly in those early teen years when students are deciding which electives they want to study."

Dr Alex Schumann-Gillett, a 25-year-old with a PhD in computational biochemistry from the Australian National University, said she could have really used a program like this when growing up.

"As a younger girl, I had a keen interest in science and technology, but not necessarily the confidence or reassurance to know where following that interest could take me," Dr Schumann-Gillett.

Dr Schumann-Gillett said she was often asked, particularly by older people, why she wanted to do science.

"These questions around the legitimacy of STEM career paths are formed, in my opinion, by people who unfortunately haven't had the chance to experience the wonderful world of STEM themselves," she said.

"Questions around career legitimacy are consistent barriers to young people - and particularly women - backing themselves and having the confidence to continue down a STEM path. The Academy for Enterprising Girls provides an opportunity for girls to play, test, discover and grow, that minimises barriers."
