Senior home affairs official says no major changes planned to ‘scientifically calibrated’ focus on terrorism after attack

Australian security agencies had no information to suggest the man accused of the Christchurch mosque massacre should be placed on a watchlist or prevented from leaving the country, a Senate committee has heard.

However, there were no major changes being made to Australia’s “scientifically calibrated” focus on different types of terrorism, the home affairs department secretary, Michael Pezzullo, said.
