Australia is a major contributor to the Extraordinary Chambers in the Courts of Cambodia and has to date committed $22.96 million to the ECCC. Australia has also provided funding to support public outreach campaigns and is an active member of the Principal Donors Group in New York and 'Friends of the ECCC' group in Phnom Penh. The first Cambodian and international judges (including Australian Rowan Downing QC) and prosecutors were sworn in on 3 July 2006.
On September 26, 2014, Australia and Cambodia signed an agreement which will allow refugees from Australia to resettle in Cambodia, which sparked criticisms from rights group such as Human Rights Watch, Freedom House, and the UNHCR. Cambodians, including Buddhist monks, protested in front of the Australian embassy against the deal citing that Cambodia "can't even look after its own", pointing to poverty and human rights concerns in Cambodia.
