The NSW Department of Education has denied the existence of the staffing issues at Howlong Public School that led to teachers striking this week.
"There are no unfilled vacancies at Howlong Public School," a spokesperson for the department said.
NSW Teachers Federation representative John Curtis said teachers elected to strike because the school had been unable to get casual replacements for absent staff on more than 30 occasions.
The department spokesperson said that all rural and remote schools were part of the Teach Rural program which fills vacancies as they arise.
"To date we have filled almost 3200 teaching positions in 2021," they said.
"The number of current teacher vacancies in NSW public schools represents approximately 1.5 per cent of overall teaching roles."
