Hutton made a notable London concert debut at Cadogan Hall as the guest soprano soloist with the Royal Philharmonic Orchestra in Górecki’s Symphony of Sorrowful Songs. Her performance was met with critical praise, with The Times lauding her interpretation as a "sweet and sorrowful" centerpiece to the evening. Expanding her repertoire on the British festival circuit, Hutton appeared as the guest soprano soloist for Mozart’s Requiem at the prestigious Three Choirs Festival inside Gloucester Cathedral. Collaborating with the Philharmonia Orchestra and conductor Simon Halsey, her vocal contribution received warm critical acclaim. Notably, Seen and Heard International commended her performance, spotlighting "the consoling voice of Alexandra Hutton in ‘Te decet hymnus’" as a standout element of the performance.

Alexandra has made several notable appearances at Berlin's premier concert halls. At the Berliner Philharmonie, she debuted as the Second Flowermaiden in an excerpt from Wagner’s Parsifal under Sir Donald Runnicles. She returned to the venue to perform the role of Taumännchen (Dew Fairy) in Humperdinck’s Hänsel und Gretel, conducted by Marek Janowski with the Rundfunk-Sinfonieorchester Berlin—a performance recorded live and released on the Pentatone label. She reappeared at the Philharmonie as Ortlinde in Act III of Wagner’s Die Walküre for Musikfest Berlin, conducted by Runnicles with the Orchester der Deutschen Oper Berlin and featuring Sir Bryn Terfel as Wotan. Later that year, Hutton made her debut at the Konzerthaus Berlin as the principal soprano soloist for its festive Christmas concert series in the Grand Hall, performing a program of Bach, Händel, Vivaldi, and Mozart alongside the Kammerorchester Berlin under Igor Budinstein.

Alexandra grew up in Bingara, a small town in regional New South Wales. She trained in piano and flute, sang in the national children's choir Gondwana Voices, and at 16 won the Globe Shakespeare Festival National Shakespeare Competition as Kate in The Taming of the Shrew.

After graduating from the Sydney Conservatorium of Music, she joined Opera Australia's Oz Opera Schools Company, singing Pamina (The Magic Flute) and the title role in Cinderella (La Cenerentola). She continued her studies at the Royal College of Music in London, where she was a finalist in the London Bach Competition and the Jackdaws Vocal Competition. While still based in the UK she sang Adina (L‘elisir d‘amore), Marzelline (Fidelio), Blondchen (Die Entführung aus dem Serail), Comtesse Adele (Le Comte Ory), Rosina (Il barbiere di Siviglia), Mabel (The Pirates of Penzance), and Yum-Yum (The Mikado). She went on to win 2nd Prize (Operetta) and the Deutsche Oper Berlin Sonderpreis at the International Belvedere Competition in Vienna.

She was a Verbier Festival Young Artist where she worked with Sir Thomas Allen, Thomas Quasthoff and Ileana Cotrubas. As a Britten-Pears Young Artist, she sang Miss Wordsworth in Albert Herring opposite Dame Felicity Lott, directed by Oliver Mears, now Artistic Director of the Royal Opera House.

Alexandra is returning to the stage after a 3.5-year break, during which she welcomed her second child and focused on her young family. She lives in Stuttgart, Germany.
