A Brisbane mother-of-four has been charged with supporting terrorism after being arrested trying to board a plane in Sydney airport, over the weekend.

The 29-year-old was caught carrying cash and equipment including camouflage gear for her husband who is fighting in Syria.

The woman was arrested as she and her four young children tried to board a flight in Sydney about 8:30pm on Saturday, The Daily Telegraph reports.

Shortly after her arrest, she was taken to nearby Mascot police station and later charged.

Three search warrants were also executed in Sydney and Brisbane.

Soon news of the woman’s arrest spread on social media.

And a group of hardline supporters gathered at the police station clamouring of her release, promoting police to call in back-up to deal with them.

The woman was granted bail and will appear at Downing Centre Local Court on June 2.

Her passport reportedly has also been confiscated.

“As per the sister who was stopped at the airport last night she and her kids are now safe with family but passport has been taken,” a post read on the Al-Risalah Facebook page, a meeting place for young Muslims.

More than 100 Australians, mostly young men, have travelled to Syria to join the fight in the civil war.
