How are some Australian sex offenders named and not others?

I've noticed that the extended supervision order prevents the public knowing Australian sex offenders, but how come we hear about the teachers being sex offenders or names like Geoffrey Leondard and Brian Keith Jones? ThanksHow are some Australian sex offenders named and not others?My guess is that the law excludes pedophiles from the law so parents can know the names so they can keep thier kids safe z
