"I feel honoured to have signed at this club and couldn't have done it without the support of everyone in Newcastle. It's been a long journey to get to this position and I am very grateful to everyone involved at the Newcastle Jets, the members, supporters, fans and close friends.
"I would like to thank you for all your support and I extend my sincere appreciation to Jess [Vanstrattan], Scott [Miller] and JP [Jean-Paul de Marigny] who turned my whole world around by helping me regain my confidence and head in the direction of my dream.
"I dedicate this next chapter in my journey to Jess. He has been my strength and mentor for the last 12 months and I don't have the words strong enough to thank him.
"I'm happy to see that the Newcastle Jets are heading in a positive direction with the Ledman Group taking over the club and I wish you all the best of luck for next season.
"It has been an amazing journey and I look forward to the next two years playing for Swansea City AFC."
