Canberra: Australia's foreign minister said on Friday she had raised with her Iranian counterpart the fate of an imprisoned Australian-British academic after a report that the woman had urged the Australian government to help free her.

Melbourne University academic Dr Kylie Moore-Gilbert is planning another hunger strike in an Iranian prison, supporters say.

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.
