Adelaide resident Mat says his sister-in-law in China has been unable to return home to care for her three children for five weeks, since a COVID-19 lockdown began in Xinjiang.
"She works in a factory, and her husband works at a different factory," said Mat, an Australia Uyghur who does not want to use his full name for security reasons.
"When the lockdown [started], they were locked down in their workplaces and weren't allowed to go home. The kids were all by themselves.
