There's no evidence that any intelligence agency suspected a terror attack would take place before the Bondi Beach massacre, a high-level probe into the attack has been told.
After hearing first-person accounts of rising anti-Semitism within the community, a royal commission on Monday began looking at potential failures of security agencies to stop the December 14 mass shooting, which left 15 people dead.
The first witness giving evidence is ASIO director-general Mike Burgess, followed by senior officers from the Australian Federal Police and NSW Police.
Two representatives from Jewish security organisation CSG NSW are also due to appear.
Before witnesses were called, counsel assisting the royal commission Richard Lancaster outlined what was expected to come from the evidence, including that the massacre was a "surprise attack".
