The federal government has requested that Australian officials be present at the trial of Australian journalist Cheng Lei, which is set to begin on Thursday.
Foreign Minister Marise Payne said such a request is in line with China's obligations under the bilateral consular agreement.
"We expect basic standards of justice, procedural fairness and humane treatment to be met, in accordance with international norms," Ms Payne said in a statement.
She said Australian officials have been able to regularly visit Ms Cheng, with the last visit on 21 March.
"The Australian Government has regularly raised serious concerns about Ms Cheng’s welfare and conditions of detention," she said.
Ms Lei, who worked as a television anchor for Chinese state media for a decade before being detained in 2020, was formally arrested a year ago on suspicion of illegally supplying state secrets overseas.
She will be tried in the Beijing No.2 People's Intermediate Court at 9am next Thursday, news agency Reuters confirmed with sources who did not want to be named because of the sensitivity of the matter.
Australia has previously said it was concerned by what it said was a "lack of transparency" over the case, and Ms Cheng's family have said they are convinced she is innocent.
China's foreign ministry did not immediately respond to a request for comment, but has said previously Ms Cheng's rights were being fully guaranteed.
She has been separated from her children, aged nine and 11, who were visiting their grandmother in Australia when she was detained.
Ms Cheng was born in China but moved with her parents to Australia as a child.
She built a television career in China, first with CNBC and later as a television anchor for China's English-language channel CGTN, and is a high-profile member of the Australian community in Beijing.
Diplomatic relations between Australia and China have worsened in recent years, after Canberra called for an international investigation into the source of the pandemic in 2020 and Beijing responded with trade reprisals.
