About Us

At the heart of Mirabilis Collective are its co-founders, Stephanie Nicholls and Tresna Stampalia, whose friendship and creative collaboration date back to their university days. Over the years, their shared journey through orchestras, chamber music ensembles, and Australian touring musical theatre productions revealed a common truth—women’s contributions to music were underrepresented on stage and in programming.

Mirabilis Collective was born from a vision to change that narrative, creating a space where women musicians could collaborate, perform, and champion one another’s work. The ensemble brings together established and emerging artists, each contributing unique strengths and perspectives to a vibrant, evolving musical community.

We are building a bold, intergenerational community where women in music connect, collaborate, and elevate each other—ensuring their voices shape the future of chamber music.

Mirabilis Collective is a dynamic community of women musicians, where the exchange of ideas and experiences fuels artistic innovation and creative collaboration.

We embrace an intergenerational approach, valuing the insights, skills, and unique perspectives that women of all ages bring to music-making. This blend of experience and fresh creativity is essential to our evolving and sustainable approach to chamber music..

Our performances honour and amplify the contributions of women composers and musicians. We create musically enriching concerts that celebrate resilience, artistry, and storytelling through sound, ensuring women's voices remain at the forefront of the arts.

Join us at Mirabilis Collective as we connect, create, and inspire. Experience the power of women collaborating in music.
