A fatal shark attack occurred in Sydney, Australia, on 23 January 2026. Reporting indicated that the victim was a 12-year-old boy who died as a result of injuries sustained in the incident. The shark species involved was not identified in available sources.

A separate account described a surfer sustaining a leg amputation in connection with a shark attack in Sydney around the same period. It is unclear from available information whether these accounts refer to the same incident or two distinct events. No further details regarding the victim's identity, the precise location within Sydney, or the activity being undertaken at the time were confirmed across sources.

Sydney's coastline borders the Tasman Sea and is known for regular surf activity. Shark interactions, while infrequent, have been recorded along New South Wales beaches over many years. Authorities had not publicly identified the species responsible as of the time of reporting.
