Four Corners

Four Corners exclusively brings you the story of the Sharrouf children and their grandmother's epic fight to find them and bring them home to Australia.

If there was one family that represented the alarming tide of Australians flocking to the black flag of Islamic State, it was the Sharroufs.

Reporter Dylan Welch and producer Suzanne Dredge have documented the family's experience for four years, travelling with the children's grandmother as she tries to convince the authorities in Syria and Australia to release the family into her care and allow them to return home.

The idea that anyone would willingly confess to a crime they didn't commit sounds unbelievable, particularly when the punishment may be life in prison or even the death penalty.

But a series of high-profile cases across America has revealed a slew of wrongful convictions based on false confessions and placed the spotlight on a widely used police interrogation technique designed to make people confess.

Across Australia the university business is booming. Higher education institutions that only a few years ago were cash strapped are now flush with billions of dollars brought in from fee paying international students.

But there are growing concerns about the consequences of the overseas student boom.

Four Corners investigates how Australia's higher education system is being undermined by a growing reliance on foreign fee-paying students.

It's almost three years since Four Corners exposed shocking revelations of mistreatment in the Northern Territory's Don Dale youth detention centre in Australia's Shame, sparking a Royal Commission.

Now the program is set to reveal a new child detention crisis in another part of Australia, where children as young as 10 have been held alongside adult criminals in maximum security facilities.

With exclusive access, the program goes behind the locked cell doors to reveal how young people, most of whom have not yet been convicted of a crime, are being held, sometimes for weeks at a time.
