On 13 July 2013, Ellis signed a two-year deal with the Sydney Kings of the National Basketball League.[1][5][6] However, his arrival in Sydney was delayed until December 2013 while he completed his studies in business at Saint Louis.[7] He made his debut for the Kings on 3 January 2014 against the Cairns Taipans,[8] and in 16 games during the 2013–14 NBL season, Ellis averaged 5.1 points and 3.1 rebounds per game.[9]

Ellis entered the 2017–18 NBL season eight kilos lighter.[17] However, a bout of chicken pox kept him out of the NBL pre-season blitz.[18] Ellis started the 2017–18 season out of the rotation after management at the Hawks sent down the edict to the coaching staff that he wasn't to play.[19][20] Eventually he hit the floor and finished the season strongly.[20] In 20 games for the Hawks in 2017–18, he averaged 6.7 points, 1.4 rebounds and 1.0 assists per game.
Every year between 2014 and 2023, Ellis played for the Warwick Senators in the State Basketball League (SBL) / NBL1 West.

Ellis' first three seasons in the SBL saw him average over 22 points per game.[28][29] With the league's change from 48-minute games to 40-minute games in 2017,[30] his scoring average dropped to 17 per game,[31] which then dropped to 14.5 and 13.4 in 2018 and 2019 respectively.[32][33]
Due to the COVID-19 pandemic, the 2020 SBL season was cancelled.[34] Ellis later played for the Senators in the West Coast Classic,[35][36] where they won the title with a 96–81 victory over the Perry Lakes Hawks in the grand final.[37] In 13 games, he averaged 14.69 points, 4.62 rebounds and 5.08 assists per game.[38]
