‘We’re looking at a very young cohort’: Counter-terror chief warns ISIS is targeting teenage Australian Muslims

ISIS is targeting young Australian Muslims and the age of recruits is rapidly decreasing, the head of the country’s security agency says.

ASIO Director-General Duncan Lewis has warned of the emergence of increasingly young Islamist extremists, whose activities will continue to impact Australia’s security environment.

In 2013, 45 per cent of Sunni Islamist extremists that were being investigated by his agency fell in the age group of 25-34.

In 2015, 40 per cent of those under investigation were aged between 15 and 24.

‘It basically dropped by a decade in the space of a couple of years,’ Mr Lewis told a Senate estimates committee on Tuesday night.
