Cambodia deal faces renewed criticism

The Cambodia deal has been slammed following reports one of the four refugees resettled there has returned to their home country.

Labor and the Greens have ridiculed a resettlement deal with Cambodia amid reports one of only four refugees sent there has returned to their home country.

Opposition Leader Bill Shorten told reporters in Sydney on Friday spending "about $10 million a pop is ludicrous".

Greens senator Sarah Hanson-Young said $55 million was an "expensive return ticket".
