The first witness due to give 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.
Among the issues under scrutiny will be security arrangements for the Chanukah by the Sea event that was targeted by two gunmen and what was known by counter-terrorism agencies and police about the shooters.
