Two large sharks have been captured off Sydney beaches in the past week, following the fatal mauling of British dive instructor Simon Nellist.
The Department of Primary Industries (DPI) has confirmed the sharks have been captured on SMART drumlines in recent days, before being tagged and released.
Officials said neither creature was suspected to be the "at least three metre" long great white suspected of killing 35-year-old Simon - rather, the two animals were tiger sharks ranging from 1.5 to almost two metres.
