This white paper examines the administrative and financial burden created by cross-jurisdictional teacher regulation in Australia. It considers how duplicated registration, accreditation, child-safety checking, fee, renewal, suspension, and evidence-transfer processes affect teacher workforce availability, particularly for casual, returning, regional, border, and interstate teachers. Using supplied case material as an anonymised practical source, the paper argues that teacher regulation should protect students while avoiding unnecessary loss of educational capacity. It proposes a whole-of-government review of teacher regulatory burden, improved source-authority verification, clearer fee and leave pathways, better renewal communication, and functional coordination between teacher-registration and child-safety authorities.
