Mark Labelle reports the first pictures of Kylie More Gilbert on Australian academic on her way to freedom, releasing her face mask in front of the Australian ambassador to Iran after two years in prison.

She was facing another eight years in an Iranian prison, wrongfully imprisoned there, wrongfully convicted and it is incredibly essential that we did the work that was done to secure at least and see her coming home coming the other way.

State controlled TV also reveals three arrivals, seemingly in exchange for the British Australians release being heralded by Iran's deputy foreign minister.

The Melbourne University lecturers exit comes after she was tried in secret on charges of spying, which she denies.

She was held at a notorious prison in the desert and let it be known she had rejected an offer from Iran to become a spy.

In a statement, Dr Moore Gilbert thanked Australian officials and said, I have nothing but respect, love and admiration for the great nation of Iran on its warm hearted, generous and brave people.

It is, she said, with bittersweet feelings, that I depart your country despite the injustices which I have been subjected to.

The prison conditions would not have been good that Carly had been living through, especially in the section where the Revolutionary Guard, um, where she'd been detained, because we know that ill treatment and torture is quite prolific there.

Theo British government has yet to secure the release of the British Iranian charity worker, Nazanine Zachary Ratcliffe, who was jailed on spying charges in 2016 and has always maintained her innocence.

Her husband, Richard Ratcliffe, said this latest release shows deals are being done but didn't know what it meant for his wife's situation.

Yeah, I just really fell in love with the people.

Iranian state media insists they've exchanged a Zionist spy, but Dr Moore Gilbert supporters say they are over the moon.

Amazing friend and colleague is on her way home.
