Kemp, 24, who has also enjoyed a stint with the New Zealand Warriors and a brief spell with Sydney rugby union club Southern Districts, has signed a one year deal with the Dragons.
Dragons chief Peter Doust said Kemp’s signing means the club’s squad for 2012 is now complete.
“Denan is keen to revive his rugby league career and we are pleased to welcome him to our Club,” said Doust.
“Denan is extremely fast and a great finisher who can play wing, fullback and centre. His versatility makes him a great addition to our 2012 roster and I look forward to seeing how he progresses under Head Coach Steve Price and the Dragons coaching team.”
