Later, she graduated from a Bachelor of Music with distinction at the Queensland Conservatorium, having studied voice with Dr Margreta Elkins AM. Her love of music and performance has led her to appear in a range of roles that include her current engagement as a Young Artist for Pacific Opera, and a regular soloist for Verismo Studio's gala concerts.
Other engagements have included performances in Beethoven's Symphony No. 9 with Sir Neville Marriner and the Academy of St. Martin in the Fields, and in Aida, The Grand Spectacular. Qestra's versatility as a singer has enabled her to explore a variety of genres with various instrumentalists including renowned classical guitarists and chamber ensembles. Initially spurred by an interest in vocal science, and a desire to help people, Qestra pursued a career in biomedical engineering.
This led to her work internationally in research for world-leading medical institutions. In 2011, she was awarded a Doctor of Philosophy for her groundbreaking work in respiratory engineering.
