Mamer Thuch doesn’t know exactly when he was born but he thinks it was sometime in the early 1980s.
He chose 23 August 1982 as his birthdate for his humanitarian visa application to enter Australia, and that’s what all of his documents now say.
A Christian from the Dinka tribe, he was born in a village near Bor in Jonglei state, before South Sudan gained its independence.
In 1991, Mamer fled his village after it was invaded by rebel soldiers from the Nuer tribe. The following year, he and his mother joined thousands of others crossing the border into Kenya, to the relative safety of Kakuma refugee camp.
During his disrupted childhood, Mamer witnessed extreme acts of violence, including people being tortured and killed.
