You are in Australia and the person doing this is in the United States. You report at home, and at the same time trigger action where they actually are.
000 (Triple Zero) for immediate danger, threat to life, or a crime in progress. TTY 106 is the text-based emergency service via the National Relay Service for people with hearing or speech impairment; 112 also routes to emergency from mobile and satellite phones (it redirects to 000 with no call priority).
Most people here are not in an active emergency. To start an official record, use the non-emergency steps below.
Keep doing everything below in Australia. At the same time, the fastest leverage often sits in the United States, where the person actually is.
The fastest practical levers against a U.S.-located perpetrator are: (a) platform reporting and content removal directly to the host service (the U.S. has no general government takedown order against a private individual's speech, and platforms have Section 230 immunity for user posts, so the platform's own abuse/terms process is the front-line removal tool); and (b) a state civil or criminal protective / restraining order (a stalking or harassment protection order, process varies by state), which once issued is enforceable against the U.S.-located respondent and makes any further contact a new, more readily charged offense. Where the conduct is interstate threats or cyberstalking, a U.S. federal case (18 U.S.C. § 875(c), § 2261A) opened via the FBI is the route to criminal action and to compelling evidence from U.S. providers.
A foreign victim whose harasser is located in the United States does not file with U.S. federal agencies from abroad and wait. The reliable inbound path is police-to-police: report the matter to your own national police / cybercrime unit in your home country and ask them to channel it to U.S. authorities. Two official conduits carry it: (1) INTERPOL, where your country's National Central Bureau transmits the request to INTERPOL Washington (the U.S. NCB inside the DOJ, the U.S. contact point for the 196-member INTERPOL network), and (2) a Mutual Legal Assistance Treaty (MLAT) or letter rogatory, the formal government-to-government request handled on the U.S. side by DOJ's Office of International Affairs, used to compel evidence such as subscriber records and content from U.S. platforms. U.S. platforms (where most of the abusive content sits) are themselves in the U.S., so a U.S.-based investigation or valid U.S. legal process is the lever that reaches them. In parallel, a victim can and should file directly with the FBI Internet Crime Complaint Center (https://www.ic3.gov) and the FBI tip line (https://tips.fbi.gov); IC3 accepts international complaints and may refer them to the appropriate U.S. or partner agency.
There is no single U.S. government body that will unmask an anonymous account or order a takedown on a foreign victim's request without a U.S. investigation or U.S. legal process. The most effective sequence is: preserve evidence (dated screenshots, URLs, usernames, headers), report to your home-country police so they can engage INTERPOL Washington / the MLAT process, file directly with the FBI/IC3, and pursue platform removal plus a state protective order against the named or identified U.S. perpetrator.
File a non-emergency report, and do the single most important thing: get your report / reference / occurrence number. That number is the key that unlocks platforms, prosecutors, employers and protective orders.
Primary channel to START AN OFFICIAL RECORD for cyber-enabled harassment, online abuse, image-based abuse with an online element, online threats, impersonation/identity theft, and online extortion. You receive a reference number; the report is routed to the relevant state, territory or federal police for assessment. It is a national policing intake/triage tool, not an investigator, and submitting it is NOT the same as making a formal police statement.
Call to report a non-urgent crime or incident and get it logged with police; a call-taker creates a record and your local police can action it. Ask for the event/reference number for your paper trail.
For a robust paper trail on stalking, intimidation or threats, attend a local station and give a formal statement; this creates an official occurrence/event number and is the basis for charges and for an AVO / personal safety intervention order. ReportCyber feeds the same police, but a station statement carries more weight.
File here in addition to, not instead of, your local police report.
INTAKE and REFERRAL, not investigation. Online portal where individuals and businesses report cybercrime including cyber abuse, online image-based abuse, online fraud, identity theft with an online component, and online threats. Issues a reference number and routes the report to the appropriate state, territory or federal police jurisdiction for assessment. Not every report is investigated; reporting also feeds intelligence and disruption. Submitting a report is NOT the same as giving a formal police statement.
CIVIL takedown/removal regulator, NOT a criminal prosecutor. Runs the Adult Cyber Abuse Scheme (18+), the Cyberbullying Scheme (under-18), the Image-Based Abuse Scheme and the Online Content Scheme. Can investigate complaints and issue REMOVAL NOTICES to platforms and end-users; non-compliant services can face civil penalties of up to 500 penalty units. For ADULT cyber abuse the threshold is deliberately HIGH: content must be menacing/harassing/offensive AND likely intended to cause SERIOUS HARM (serious physical harm or serious harm to mental health, including serious distress). For most schemes you must FIRST report to the platform or service before eSafety will act. eSafety does not prosecute, award damages, or replace police.
Investigates serious, complex Commonwealth cybercrime and transnational matters; hosts the INTERPOL National Central Bureau (NCB) Canberra for cross-border liaison. Most individual harassment cases are handled by STATE police; the AFP engages on serious threats, organised or cross-border offending.
