A whirlwind 12 months has followed, starting with him returning Down Under for family reasons, helping his new team to a Grand Final and then completing the unlikely feat of representing Greece at a Rugby League World Cup.
For now, his career is likely to be defined by two chip kick plays – a quite handy signature move for a stocky forward to have in his armoury.
His most famous, for Newtown Jets in their 2019 NRL State Championship victory, saw him chip over the top for Jackson Ferris to score the winning try against Burleigh Bears barely seconds from the end.
While his replica of it for Greece against France in Doncaster back in October mattered little to the outcome of the game, it will no doubt have been just as special for a man proudly representing his heritage.
Billy Magoulias made just eight appearances for Warrington after arriving as a late signing to boost Daryl Powell’s forward pack in what turned out to be a turbulent first year in the job for the former Castleford coach.
In his first two games, Magoulias saw his side dumped out of the Challenge Cup at home by Wakefield and then mauled away by Hull KR in a game which they arrived late for.
He would at least taste three victories during his brief spell, but the 40-4 home defeat to Leeds at the beginning of June proved to be his last outing and it’s unlikely he’ll ever make a return to Super League.
Magoulias said: “I signed a one-year deal with Warrington and after a while, my missus got pregnant so the whole living in England thing wasn’t working for me and I just had to be realistic about that. Obviously you’ve got to do what makes your family happy because that’s why I do it. We ended up going back to Australia, because I wanted to raise my kid around family. That was a major reason as to why I left.
“With Warrington, I wasn’t sure if I was going to be there the year after and I didn’t even look at signing for another (Super League) club.
