It seems that NESA has extended the study of the current modules and their respective prescribed texts for an additional two years, which is definitely interesting to see. This sounds like good news for students who will be completing their HSC in 2024 and 2025, given the wealth of resources and other relevant material that they will gain access to once they reach Stage 6.
Provided NESA does not intend to further extend the current HSC English syllabus beyond 2025 (extending the current HSC English syllabus beyond 2025 is unlikely), I believe that a syllabus change will likely occur in 2026.
I hope this helps!
