Griffiths has played for Liaoning and more recently Beijing Guoan in China for the past three seasons and comes on the back of the re-signing of star youngster Ben Kantarovski last week, and coach Branko Culina’s four-year contract renewal late last month.

Ryan played for Newcastle United in the National Soccer League 52 times between 2002 and 2004 and made his international debut for Australia in September 2006, making his last appearance in 2008 against Singapore.

“I played most of my career in Australia in Newcastle so to be able to come home and play with the Jets is really exciting,” Griffiths said.

“The club is doing some great things on and off the field so I’m glad to have an opportunity to contribute.”

Jets Chief Executive Officer John Tsatsimas said the club was rapidly becoming a more appealing option for both domestic and overseas-based players.

“When you’re able to attract great overseas-based talent such as Ryan you know you are heading down the right track,” Tsatsimas said.

“Our squad is going from strength to strength under Branko’s leadership and we hope to continue to make great strides off the field.

“We look forward to welcoming Ryan into the fold and into a Jets jumper.”
