Refoulement from PNG

Dear Prime Minister,

In the Parliamentary Research Paper, 'Australia's offshore processing of asylum seekers in Nauru and PNG: a quick guide to statistics and resources,' a table shows the number of departures each month from Nauru and PNG. For the period Jan 2014 - Jun 2015 it shows the destination countries of the returned asylum seekers. However from August 2015 onwards there is no information about the destination countries. Does Australia follow up the fate of each of the returnees? If they have been returned to danger then Australia has committed the international crime of refoulement.

Refugees in PNG report that a total of 6 men have been deported to danger in Bangladesh between 4th and 20th March 2018. Will they be recorded as 'destination unknown.' Were they stateless Rohingyas? What is their fate?
