Border Force stops 300 people 'of concern'

More than 300 people were stopped at Australian airports last year over national security concerns, including minors wanting to fly to conflict areas in Syria and Iraq.

The Australian Border Force's counter-terrorism unit stopped 336 passengers in the 12 months to June 2015, following around 135,000 assessments of travellers across the country.

"Upon examination of persons of concern, the CTU teams have found evidence of significant movements or attempted movements of large sums of cash, and images and material of an extremist nature," the now-defunct Australian Customs and Border Protection Service's 2014-15 annual report said.
