Most industries we work in have retention obligations measured in years. RTOs have obligations measured in decades, for some assessment evidence. That changes the shape of the backup conversation, the shape of the identity conversation, and the shape of what "we've always done it that way" actually implies about the records currently on the network.
The other RTO-specific pattern is the volume of third-party systems. A Student Management System, a Learning Management System, an assessment platform, an accounting and payroll stack, training venue platforms, and the AVETMISS submission pipeline each have their own security posture. Most RTOs accumulate these over years and never audit the aggregate access picture. We do.
On audit: ASQA doesn't audit IT, but almost every clause they audit depends on IT-held evidence. Walking into an audit with a clean evidence pack (retention policy, access register, backup proof, SMS audit log) means the auditor spends their time on training-quality questions, not on whether your records are real. We build and maintain that evidence pack as part of the service, not as a panicked six-weeks-before exercise.
