The 37-year-old is proud of his Irish roots, but is reluctant to take the place of younger players who have shown more commitment to the Irish cause over the last four years.
Lynch has spoken to Ireland coach Mark Aston on a number of occasions about playing for the Wolfhounds in the past, but injury has prevented him pulling on the green jersey.
“It’s hard to say, it’s still preseason,” he told Love Rugby League.
“I don’t know if it’s right to say it, but I can’t just put my hand up now when I’ve never done it before.
“I’ve had conversations with Mark before about playing, but with the injuries I’ve had I haven’t played.
“I can’t just put my hand up and say I want to play because the World Cup is on.
“It’s tough on the other guys, because people work really hard and their goal is to get into that Ireland squad at the end of the year.
“It’s only fair that those players who work hard all year don’t miss out and play in that squad.
“It’s still early days, I’ll see how things go.”
“I think what’s we want, we need competitive games at international level,” he added.
“Scotland showed when they played the Kiwis, that the quality coming through is getting better and better.
“The only way to get better is to play these teams year on year. If we can do that it’s better for the game.
Lynch also thinks that seeing more players from elsewhere in Europe playing in Super League would give the game a boost at the moment.
“Of course it would,” he said.
