Chaotic scenes have unfolded at Melbourne Airport after a group of ISIS brides and their children arrived from Syria on Thursday night.
After being held in customs for several hours, ISIS bride Zahra Ahmad was shielded from the media by a large group of men dressed in black as she was escorted through the airport terminal.
While Ms Ahmad was making her way to a waiting mini bus, a TV reporter asked her 'why did you marry an ISIS terrorist?', to which a male member of Ms Ahmad's entourage responded: 'Shut up you s***.'
Ms Ahmad, 33, arrived in Melbourne with her mother Kawsar Abbas, 54, sister Zeinab Ahmed, 31, along with eight children, almost two weeks after leaving the Al-Roj detention camp in northeastern Syria.
Abbas and Zeinab were arrested by AFP officers and formally charged on Friday morning.
Only Ms Ahmad was allowed to walk free without any charges laid.
Abbas was charged with four crimes against humanity - slavery charges, including keeping and using a slave, and engaging in slave trade.
These offences carry a maximum penalty of 25 years' imprisonment.

Police will allege she travelled to Syria in 2014 with her husband and children, and was complicit in the purchase of a female slave for US$10,000, and knowingly kept the woman in her home.
Zeinab faces two slavery charges. Both offences carry a maximum penalty of 25 years' imprisonment.
Zeinab travelled to Syria in 2014 with her family and knowingly kept a female slave in the home.
The pair are expected to face Melbourne Magistrates Court later on Friday.
The widow of a notorious Islamic State recruiter, Ms Ahmad had previously pleaded with Australians not to 'judge' the ISIS brides.
The latest cohort travelled to Australia with Janai Safar, 32, and her nine-year-old son, who were escorted off a plane by AFP officers shortly after landing at Sydney Airport on Thursday night.
Safar was later charged with entering or remaining in declared areas, and being a member of a terrorist organisation.
Police will allege she travelled to Syria in 2015 to join her husband, who had previously left Australia to join ISIS.
Safar is due to face Downing Centre Local Court on Friday, where she is expected to apply for bail.
