Mehmet Obul spent Tuesday night sifting through thousands of leaked images of Uyghur detainees who have been locked up by Chinese authorities.
He was both afraid and nervous that he might catch a glimpse of his sisters or nephews, who he hasn't heard from since 2016.
"We are in a very low mood and emotional right now," Mr Obul, president of the Australian Uyghur Association, said.
He and thousands of Uyghur-Australians looked through 2,884 police photographs that have been leaked by a consortium of media in what is an unprecedented look into the Chinese Communist Party's (CCP) detention camps.

It is understood police servers were hacked to reveal 452 spreadsheets outlining details of more than 20,000 Uyghurs.
But Mr Obul says the leaked documents reveal "just the tip of the iceberg" of the magnitude of the issue, and fears there are more people affected than the documents indicate.
Uyghurs are a minority ethnic Muslim group, primarily from the Xinjiang province in China's northwest.

China has long denied the alleged human rights abuses, insisting that Uyghurs were willingly enrolled in "vocational and education centres" to free themselves of "extreme views".
Others have been sentenced to years in prison for charges that include listening to Islamic lectures, growing a beard, or not recharging their mobile phones in fear they are using secretive means of communication.
"I don't have any hope for my people ... they were so disappointed," Mr Obul said.
President of the Australian Uyghur Tangritagh Women's Association, Ramila Chanisheff, said the leaked documents have renewed the community's fears about loved who ones have gone missing under CCP rule.

"Everyone is going through those pictures thinking is there a family member, is there a neighbour or someone that they studied with or somebody they may know that are in the pictures that are being released," she said.
The photos were taken between January and July 2018 in the Shufu county, in the Xinjiang region. The BBC says the leaked files were handed to them earlier this year.
According to the files, the youngest detainee at the time was 15 and the oldest was 73.

"Genocide is being committed in the 21st century and Australia needs to act and with a new government in place, prior to the election, they were speaking quite strongly how they're going to do business with China. We have to hold them to account now."

The data leak comes as the United Nations human rights chief Michelle Bachelet .
Her visit has sparked concern from Western diplomats and human rights groups who say the CCP will attempt to use it to whitewash the torture and abuse Uyghurs have allegedly been subjected to.
China vehemently denies the allegations, calling them the "lie of the century".
"We know that her treatment is going to be extremely controlled and staged by the communist regime, so we're scared that she's going to come back and give a glowing report and we don't want that," Ms Chanisheff said.
Ms Bachelet held a video call with Chinese president Xi Jinping on Wednesday, during which Mr Xi defended his country's human rights progress, according to a readout from state broadcaster CCTV which did not say whether Xinjiang was mentioned by either side.
"Human rights issues should also not be politicised, instrumentalised, or treated with double standards," Mr Xi said according to CCTV, adding that China has "a human rights development path that ... suits its national conditions".
CCTV reported Mr Xi as telling Ms Bachelet that there is no "ideal nation" on human rights.
He added that there is "no need for a teacher who is bossy towards other countries" - an apparent reference to recent public criticisms of the trip by US officials.
According to the CCTV readout, Ms Bachelet said the UN Human Rights Office is "willing to strengthen cooperation with the Chinese side".
She was also reported to have said: "I admire China's efforts and achievements in eradicating poverty, protecting human rights, and realising economic and social development."
