That would depend on when, in 2013, he arrived at or near Christmas Island and who was the express-processing Immigration Minister at the time BUT that said, Tony Burke and mealymouthed Chris Bowen both have extensive form and blood on their hands as Rudd/Gillard 'express-processing' Immigration ministers.

''On 25 March 2013, Burke was appointed Minister for the Arts in the Second Gillard Ministry, in addition to his existing responsibilities.^[2] Burke took over the implementation of the Gillard Government’s Creative Australia policy after the former Minister for the Arts, Simon Crean, was sacked for his involvement in a failed attempt to return Kevin Rudd.

Following the June 2013 Labor leadership spill, Burke’s offer to resign from the ministry was rejected by returned Prime Minister Kevin Rudd.^[19] Burke, a supporter of Julia Gillard, had been critical of Rudd's performance during his previous tenure as Prime Minister.

Rudd appointed Burke as Minister for Immigration, Multicultural Affairs and Citizenship in the Second Rudd Ministry.^[2] He also remained Minister for the Arts and Vice-President of the Executive Council.''
