The young South Sydney half is yet to pull on a Greek jersey yet, but being a near certainty to be selected for the international side for the post-season tournament, Ilias already has his heart set on who he will dedicate his debut to.
Ilias' grandfather Spyros passed away a few weeks ago, leaving Lachlan desperate to represent his 'Papou' in England later this year.
While Greek players in the NRL are stretched far and wide, the strong cultural support network around Ilias is a massive reason behind his successes.
Mamouzelos, unlike Ilias, has already donned the blue and white jersey, notching a highly impressive ten tries in seven games at hooker for the nation.
“I’m really looking forward to it, especially because my grandfather passed away a few weeks ago and he was born in Greece.
“He’s the reason why we’re here in Australia so I’m really looking forward to representing him and my family."
Ilias earlier revealed how form teammate Adam Reynolds has been messaging him support throughout the season, something Reynolds may regret after Ilias' Bunnies jumped the Broncos on the ladder during Round 21.
