Increasing numbers of young women are altering the profile of Australians joining ISIL in Iraq and Syria, Attorney-General George Brandis said Saturday, enticed by the "false glamour" of the organization.

"At an earlier time, perhaps even six months ago, we were concerned almost entirely about young men," Brandis said, according to the Australian Broadcasting Corporation (ABC).

"But a more recent estimate by the national security agencies suggests that a growing number of young women are travelling to participate in that fighting as well."

Brandis said about 90 Australians were now believed to be caught up in the conflict, compared to 70 last year, the ABC reported.

Ever more young people were being "enticed and ensnared here in Australia with the false glamour of participating in the civil war on behalf of ISIL," he added.

"The Australian people should be aware that this is a real and growing problem."
