Teresa Lemaire has come a long way on her leadership journey.
Raised in mining communities in Ghana, she went on to work and study in the USA and Australia and now holds the senior role of Superintendent of Planning, Engineering and Stores at Bell Bay Aluminium in northern Tasmania, leading around thirty people in a highly male-dominated environment. As a migrant woman leading in a male-dominated industrial environment, Teresa navigates both gendered expectations and the added scrutiny that can come with being new to a place and culture.
Back in Ghana, Teresa’s parents instilled in her a strong belief in the value of education, opportunity and resilience. It’s a mindset that has shaped her career ever since.
During her honours degree in Ghana, Teresa secured a competitive internship with General Electric in the United States. It was her first experience of life outside Africa, and one that dramatically expanded her sense of what was possible. “I was like, ‘Okay, wow. There’s this whole big world with all these different opportunities’.
Teresa later moved to Australia and began with Rio Tinto in far north Queensland, where she progressed from graduate engineer to control systems engineer and then into her first leadership role, leading a team of maintainers. Over the next seven years, she built her deep technical expertise alongside frontline leadership experience.
Determined to strengthen her leadership capability further, Teresa made a bold decision – to leave Rio Tinto and complete an MBA at Melbourne Business School. “I felt like I was lacking key skills, about leading people, about running a business,” she explains. “I wanted to make the networks, put myself out there, build that.”
It was this commitment to growth and connection that eventually led Teresa to the I-LEAD Women in Industry program, after she had moved to Tasmania and started with Bell Bay Aluminium. “I was looking to build a local network. As a migrant, I needed to connect with people around me.”
The program delivered on that promise. “When you sit in a room with like-minded people, with everyone sharing their experience and insights, that’s powerful.” And the network has endured. “I’m hoping I can stay connected with the network for a long time and that it will continue to challenge me.”
The I-LEAD Women in Industry program also clarified Teresa’s leadership philosophy as one grounded in empathy and strength. “I love to see my people thrive,” she said. “I like to help them with the roadblocks so they can get to that end goal and feel proud.”
Teresa is already applying what she learned from the program. “My approach has been more intentional,” she said, including how to turn difficult workplace relationships into productive ones. “I’m getting a lot more of a positive response.”
For Teresa, that childhood belief in the power of education, opportunity and resilience remains as strong as ever and continues to shape her as a leader. “It doesn’t really matter what happens, I know I can get to it and come out with something positive.”
Through I-LEAD, Teresa has deepened her leadership toolkit and sharpened her resolve to lift others up, especially women. Her story shows what changes when women have access to networks, sponsorship and authority – alongside technical expertise.
