Foreign Minister Marise Payne declined to detail her conversation with Mohammad Javad Zarif about convicted academic Kylie Moore-Gilbert on the sidelines of a global leadership conference in India.
"This is not a detention that we support. We don't accept the charges,"Payne told the Australian Broadcasting Corporation in New Delhi.
"I don't think it's appropriate to talk about the details of that conversation,but to assure Australians and to assure Dr Moore-Gilbert's family that I have raised that matter again,"she added.
Moore-Gilbert,a Melbourne University lecturer on Middle Eastern studies,has been held in the notorious Evin Prison in Tehran since September 2018. She was arrested at Tehran airport while trying to leave the country after attending an academic conference.
She was convicted of spying and sentenced to 10 years in prison. A recent appeal was rejected.
The Guardian reported Moore-Gilbert wrote in June to Prime Minister Scott Morrison:"I beg you to act faster to bring this terrible trauma that myself and my family must live through day after day."
She wrote again in December:"Six months have passed...during this time I have remained in the same prison without any improvement in my intolerable conditions,"the newspaper reported.
