  • Donna Marwick-O’Brien – Creative Director

    Donna is the Creative Director of One Big Voice and the driving force behind much of what happens behind the scenes. From writing and arranging repertoire to developing resources, planning events and supporting teachers, she works to ensure that every aspect of OBV reflects its mission of bringing young people together through positive, uplifting music.

    A music educator, songwriter and conductor with more than 30 years of experience, Donna has a passion for creating songs that children love to sing and that spark meaningful conversations about courage, kindness, resilience and connection.

    In 2021, Donna received the Australia Day Individual Award for the City of Wanneroo in recognition of her contribution to music education and community engagement. She was also awarded the National Award for Excellence in School Music Education and is widely respected for her ability to connect with children through music.

    Whether she’s leading workshops, creating new repertoire or standing in the middle of RAC Arena surrounded by thousands of young singers, Donna remains committed to helping children discover the joy, confidence and sense of belonging that music can bring.

  • Kiki McCormack – Regional Director

    Kiki has a special passion for nurturing young talent and helping young people discover the joy, confidence and sense of belonging that music can bring. As Regional Director of One Big Voice, she works closely with schools, teachers and students across Western Australia, supporting the growth of the festival and helping create a positive experience for all involved.

    With more than 30 years in education, Kiki has taught children and adults in South Africa, England, Taiwan and Australia. She has led choirs, facilitated music programs and seen first-hand how singing can build confidence, foster belonging and bring people together.

    Away from One Big Voice, Kiki is an enthusiastic African drummer who loves the energy, rhythm and sense of community that djembe drumming creates. She regularly attends drumming workshops and retreats and enjoys sharing this passion through community performances and music programs.

    Kiki believes music is a universal language that transcends age, culture and background. She loves that One Big Voice brings thousands of young people together each year in a celebration of joy, belonging and community.

  • Judy Vorster – Operational Director

    Judy is the founder of the festival that eventually evolved into One Big Voice. In 2000, she established West Coast Warblers to provide performance opportunities for school choirs in an area where few existed. The festival gave choirs the chance to come together and perform for one another, fostering a love of music and singing among young people.

    Today, as Operational Director, Judy oversees student registrations, develops the annual Teacher Resource Book and designs the detailed floor plans that accommodate thousands of students at RAC Arena. On concert day, she works closely with the OBV team, Lux Events and RAC Arena staff to help ensure everything runs smoothly.

    Trained as a music teacher at the Conservatorium of Tasmania, Judy taught music in both primary and secondary schools before moving into educational assessment and literacy programs. Her organisational skills, attention to detail and wealth of experience have made her an integral part of the festival’s continued growth and success.

    For Judy, the greatest reward is seeing so many children involved in and enjoying music. The joy, confidence and sense of achievement on students’ faces is exactly what inspired her to create West Coast Warblers all those years ago.

    As Chairperson, Gail is proud to support the vision of One Big Voice and the work of the many teachers, volunteers and committee members who make it possible.
