An Indonesian court has heard a people smuggler who helped organise a voyage in which more than 90 people died had links to four men in Australia.

The 19-year-old Afghan man, named Dawood Amiri but also known as Irfan, has been found guilty of people smuggling for organising four asylum seeker boats.One of the boats Irfan admitted to organising sank north of Christmas Island last June. Of the 204 people on board, only 110 survived.At the East Jakarta district court on Wednesday, chief judge Maryana sentenced Irfan to a six-year jail term and a fine of 750 million rupiah ($75,000).What the case uncovered is more about the people smuggling network Irfan worked for and its links back to Australia.The judges described how Irfan was recruited as a UN-recognised refugee while himself attempting to get to Australia.
