There have been multiple recent shootings in Australia, and different incidents have involved different identified or alleged shooters; without knowing which specific event or date you mean, any single name would be incomplete or misleading. Because this is an ongoing and sensitive situation involving deaths, injuries, and terrorism investigations, the most accurate and safest approach is to check a current, reputable news outlet for the latest confirmed identification of the person or people involved in the particular incident you are asking about.

If you can share more detail (for example, city, state, or approximate date), it becomes possible to narrow down which case and which named suspect or deceased shooter the reports are referring to, but it is still important to rely on official police briefings and established news organizations rather than unverified social media speculation—especially because names, charges, and even the number of suspects can change as investigations progress.
