Online posts and emails can become part of a criminal investigation. Two Australian Federal Police (AFP) releases published on 3 October describe separate matters involving alleged online threats and abusive emails. Together, they show why it matters to distinguish an arrest and charge from a guilty plea and sentence, and why a public account cannot tell readers exactly how investigators examined digital evidence.
A South Australian man has been charged over alleged posts
The AFP and South Australia Police said a referral about social media posts led to an AFP National Security Investigations investigation in September. The release says the posts allegedly advocated violence against police and threatened senior officers. Police executed a search warrant in South Australia's Mid North region on 1 October, and a 34-year-old man was arrested and charged with using a carriage service to menace, harass or cause offence. He appeared in the Adelaide Magistrates Court on 2 October, was refused bail, and is due back in court on 5 November.
These are allegations, and the matter is before the courts. The charge named in the release is under section 474.17 of the Commonwealth Criminal Code. The law's heading describes using a carriage service to menace, harass or cause offence. A charge is not a finding of guilt.
A separate Sydney case ended in a sentence
In a different matter, the AFP said a 43-year-old Sydney man was sentenced on 2 October after pleading guilty to sending offensive emails to a Commonwealth official. The AFP release says the emails were sent between February and May, the investigation began after a referral in May, and the man was arrested on 23 June. The court imposed a sentence of three months and three days' imprisonment, with release on time served, as well as a 12-month community correction order and a 12-month community release order that included 100 hours of community service.
This case had reached a different procedural point: the AFP says there was a guilty plea and sentence. It should not be conflated with the South Australian charge, which remains an allegation awaiting court proceedings.
What the releases do not establish
Neither release identifies a mobile device extraction product, a digital forensics vendor, or the examination method used. They describe investigative events and court outcomes at a high level. That public information does not establish whether a particular device was seized, what data was recovered, or which forensic tool, if any, was used. Naming a commercial product or reconstructing a technical method from these releases would go beyond the available evidence.
That limit is useful for readers to keep in mind. A public statement can confirm that online communications formed part of the reported circumstances, but it may not disclose the technical steps behind an investigation. The details that matter for an individual case belong to the evidence and court process, not to assumptions drawn from a short media release.
Reading crime and cyber security reporting carefully
When following an online-crime report, check who is making each claim and what stage the case has reached. A police release can summarise an investigation or announce a charge; a court outcome may later record a plea, finding or sentence. Keeping those stages separate helps avoid presenting an allegation as a proven fact.
The two AFP releases also show why digital forensics should be discussed with care. Online material can be relevant to an investigation, but the existence of a post or email in a public account does not disclose how it was collected, authenticated or assessed. Unless an authoritative source or court record explains those details, the responsible conclusion is that the method has not been made public.
