Concerns have been raised as to whether its year 12 students from Victoria can attend classes face to face with the reintroduction of a stage three lockdown and remote learning in their home state from Wednesday.

Principal Justin Beckett said if Victorian-based students were unable to attend school at the pointy end of their secondary education it would put them "at a huge disadvantage" to those living on the NSW side.

"The schools in Wodonga are doing VCE and therefore the restrictions will apply evenly to all VCE students, whereas a border school with students doing HSC means our kids are in a different situation," Mr Beckett said.

"For our Victorian students, we want them to learn face to face wherever possible because we know it has better mental health outcomes."

Around a quarter of Trinity's 1000 students reside in Victoria.
