Julie Bishop said Canberra was working to secure the release of Katherine Jane Wilson, but insisted Australia does not pay ransoms for hostages.
Wilson, who also uses the first name Kerry, was grabbed in the city of Jalalabad, close to the border with Pakistan, on Thursday, a government official in the area told AFP.
“She visited the city of Jalalabad for a women’s embroidery project,” said Ataullah Khogyani, a spokesman for the governor of Nangarhar province, of which Jalalabad is the capital.
“And unknown masked gunmen abducted her from Police District 2 of Jalalabad city.”
He added that the kidnappers, disguised as police, took her at 4am from a home in which she was staying.
Nangarhar police chief Zrawer Zahed confirmed the abduction by “unidentified gunmen” not long after she arrived on Wednesday evening.
Bishop said she had been in contact with Wilson’s family.
“The details of the reports are still being confirmed but the Afghan authorities certainly believe she has been kidnapped,” she told reporters.
“Our priority is to ensure that she is well, that she’s being treated well, and so that’s what we’re focusing our efforts upon, working with the local authorities. Our embassy in Kabul of course is deeply involved in this matter.”
Asked if Canberra would pay a ransom if one was demanded, she replied: “The Australian government does not, as a matter of policy, pay ransom for kidnappers.”
Wilson’s 91-year-old father Brian Wilson said his daughter had worked in the region with charities related to women’s rights and water security for more than 20 years, and made an emotional plea for her release.
“I feel extremely worried indeed,” he told the Australian Broadcasting Corporation.
“But I presume she’s a hostage, and that they’ll do their best to keep her alive and not harm her, simply because they want to have something or other in return and it’s not very good having a dead hostage.”
