the teacher shortage. 11 teachers were employed by private schools and another two by interstate schools in the past two years. Most were maths, science or language teachers, all recognised areas of national shortage and positions the principal had struggled to fill. In July 2009 the school had another issue with 3 more teachers being employed by other schools. During 2012 and 2013, many teachers and support staff participated in work bans and strikes organised by the Australian Education Union as part of an ongoing dispute between the union and the state Department of Education and Early Childhood Development (DEECD) over wages and working conditions.
