'Il Barbiere di Siviglia', Opera Australia, Das Opernglas Magazin, February 2025 
"Pro fessioneller und ausgereifter in der Gesangs Technik die Rosina von Helen Sherman, meist im Mädchenzimmer oben links im Haus agie rend, für Koloratur gespickte Passagen aber im Treppenhaus und Musikzimmer unten gut gestellt und klangliche Wirkung erzielend. Ein delikater Höhepunkt - auch an musikalischer Präzision-war das rasante Quartett im zwei ten Akt. Und das intensive und punktgenaue Timing des Agierens aller verlieh der ganzen Produktion Drive und Professionalität, die zwar keine Albernheit ausließ, aber geschickt die Balance zur inhaltlichen Entwicklung fand."

"Helen Sherman's Rosina was more professional and sophisticated in her vocal technique, performing mostly in the girls' room upstairs on the left side of the house, but with passages rich in coloratura well placed and sonicly effective in the stairwell and music room below. A delicate highlight—also in terms of musical precision—was the rapid-fire quartet in the second act. The intense and precise timing of everyone's performances lent drive and professionalism to the entire production, which, while not skipping any silliness, skillfully struck a balance with the development of the content."

'Giulio Cesare', Pinchgut Opera, Sydney Morning Herald, November 2024
"Neil Armfield’s production of Handel’s Julius Caesar, is a vintage Pinchgut Opera creation for its cheeky boldness, superb musicality, freshness and delight. As Sesto, Helen Sherman, singing a travesti or “pants” role, projected a dramatic voice with vivid colour and weight in the lower register as she cries for vengeance."

'Giulio Cesare', Pinchgut Opera, Limelight Magazine, November 2024
With Lashings of on-stage chemistry, this all-conquering Neil Armfield production of Handel's Julius Caesar is a triumph. Mezzo-soprano Helen Sherman is impressive as Sesto, in a 'pants role', growing from callow youth to angry young man avenging his father's murder. She is imposing in the rage aria Svegliatevi nel cor, and wistfully sanguine in Cara speme."
