Australia boosts security as IS threat grows

As Australia moves to boost its security at airports and sports events this weekend, it's had a reminder of Islamic State's (IS) growing hold in the country.

A Sydney schoolgirl's facing charges, accused of attempting to wire money to an IS fighter.

At 16 she's too young to get her full licence or vote, but it's alleged the teen tried to send thousands of dollars to IS.

Counter terrorism police say she was enlisted by notorious Syrian fighter Ahmed Merhi.

The teen was arrested and charged along with 20 year old Milad Atai, her father insists she hasn't been in trouble before.

It's a chilling reminder of IS' growing hold in Australia -- the school girls' one of 190 Australians currently under suspicion for sending funds to Syrian fighters.

There are 400 active "high-priority" counter-terror investigations underway in Australia.

"We don't have a watch list, this is too much of a dynamic environment to have a listed number of people going up, going down," New South Wales Police Commissioner Andrew Scipione said.

More than 100 Australians are fighting with IS.

"The fact is we've had lots of young people go over and fight and the reality is many will die on those battlefields," Mr Scipione said.

So far around 30 fighters have returned to Australia but that number could rise, so the war to keep Australia safe from IS is only set to grow.
