IT will be all aboard HMAS XBox for Fall Out Boy fans when the navy turns one of its biggest warships into a party boat this month.
The US rockers will command the deck of HMAS Tobruk at Garden Island for an exclusive event to promote music-themed video games, with tickets distributed in competitions.
The concert is the second of the XBox Sounds banner "money-can't-buy" shows launched by Pussycat Dolls at the Sydney Opera House.
A spokesman for XBox Sounds said all expenses for the February 22 event were incurred on a "cost recovery basis".
"It's a free event but any costs will be incurred by Microsoft," he said. "The navy have been great, fantastic to deal with. It is something they have seen as a positive thing."
The RAN confirmed the cost arrangement was "a usual practice with defence events of this nature. A legal agreement is being drafted between Microsoft and navy to ensure there is no undue cost to navy for this event."
Rear Admiral Davyd Thomas approved the event on the basis it would convey the navy to a youth audience in a cost effective manner.
XBox will give away 400 tickets, with another 100 for HMAS Tobruk's crew of 140 personnel.
