Where do they come from?
By far the largest number of people sent to Nauru or PNG have been from Iran. The second-largest group of people are stateless. There are also significant numbers of people from Afghanistan, Pakistan, Sri Lanka and Iraq.
Unlike onshore detention, there is no regular reporting on nationalities of those in offshore facilities. The statistics are occasionally revealed in response to Senate questions on notice.
This graph shows the number of people recognised as refugees by key nationalities, by year and place.
However, that graph only includes those recognised as refugees and select nationalities. The graph below provides the most recent statistics on the number of people still in PNG and Nauru by nationality.
