​Beirut: A freed Adam Whittington has left Lebanon nearly four months after first being detained for plotting the abduction of Brisbane mother Sally Faulkner's two children from Lebanon and warned the Nine Network "the truth is coming out."

A new image of Whittington taken at Beirut–Rafic Hariri International Airport showed the ex-soldier sporting a long, thick beard and full moustache but giving a thumbs up.

"I'm sitting at a gate right now ready to fly out of Lebanon finally, thank God!" Whittington said. "I'm shocked really, we've come across so many hurdles to get out of here."

"I'm just walking on the plane now, I really can't believe it, it's been a tough four months," he said.
