Australian Van Kham Chau located within Vietnam's prison system as Government urged to act

Liberty Victoria has now started advocating for Mr Chau, saying there has been a lack of public condemnation from the Australian Government in his case.

Martin Radzaj, the chair of the criminal policy board at Liberty Victoria, said Mr Chau deserved more support from the Australian Government.

"Mr Chau is an Australian citizen currently in prison as a 71-year-old with health issues. He's been hospitalised since his arrest, the family have struggled to get his medication to him," he said.
