The jailing of an Australian grandmother in Japan is a "kick in the guts" with WA Premier Roger Cook expressing hope for the convicted drug smuggler's potential appeal.
Donna Nelson, 58, from Perth, was sentenced on Wednesday to six years for trafficking methamphetamine into Tokyo in January 2023.
Her legal team has indicated they plan to appeal, noting that the two years she's already served will count toward her overall sentence.
Mr Cook said his heart went out to Nelson and her family.
"That must come as a huge kick in the guts to that family and I know Donna and her family would be hurting today," he told reporters on Thursday.
Mr Cook said the Japanese justice system had to be respected.
"She's been found guilty of a crime and she's been sentenced and now she has avenues of appeal," he said.
"In due course, I hope we may see a situation where Donna Nelson is brought home sooner rather than later."
Japanese officials uncovered about 2kg of methamphetamine in a false bottom in a suitcase she was carrying as checked luggage and the court accepted her testimony that she was tricked as part of an online romance scam.
Nelson told the court she was carrying the case for a man she met online in 2020, who said he was the Nigerian owner of a fashion business, but she did not know that drugs were hidden inside it.
She was supposed to meet him in Japan but he did not turn up, prosecutors said, with the court finding that he paid for Nelson's travel to Japan and asked her to collect dress samples from an acquaintance during a stopover in Laos.
She was ordered to pay a fine equivalent to $A10,000 on top of her sentence after being found guilty of breaking drug and customs laws in the Chiba District Court.
Federal Health Minister Mark Butler said the Australian government would continue to provide support to the 58-year-old Indigenous woman and her family as they decided on their next steps.
"This will obviously be a really distressing result for Ms Nelson and for her family and friends," he told the ABC.
"Our government, through the usual consular pathways, has been providing support to Ms Nelson and the usual sort of consular assistance that you'd expect in a case like this."
Nelson's family members, some of whom attended the trial, said they were disappointed and devastated by the verdict.
They maintain she was "duped" and have described her as the victim of a crime, not a criminal.
"We will never stop fighting for our mum," her family said in a statement.
"And we will keep fighting until we can bring her home."
