Gallio joined NT Thunder in 2019 after an impressive NTFL season with the Southern Districts Football Club, finishing runner-up in the NTFL’s Nichols Medal, the highest individual accolade a player can win. He is a playing premiership coach in 2018 with the Millicent Football Club in the Western Border League, South Australia. Unfortunately Gallio suffered a season ending knee injury in Round 12 of the 2019 NEAFL season.
