Born in Brisbane, O'Neill played youth football for Brisbane Athletic and Burnley before making his professional debut for the latter in 2016. He spent some time on loan to Oldham Athletic and Fleetwood Town, scoring his first ever professional goal for the latter club. He returned to Australia, on loan, to play for Central Coast Mariners in 2018.
He has represented the Australian under-23 national team.
O'Neill is of Irish ancestry. He was born and raised in Brisbane, attending Nudgee Junior College before moving to Brisbane Boys' College before moving to England aged fourteen when his parents moved there for work.
On 12 January 2016, O'Neill signed his first professional contract with then-Championship side Burnley. He made his professional debut for the club on 20 August 2016, coming on as a late substitute against Liverpool in the Premier League as Burnley won 2–0. He made his full debut days later, starting in an extra time loss to Accrington Stanley in the EFL Cup.
In August 2017, he joined League One side Fleetwood Town on a season-long loan deal. In January 2018, he returned to Burnley early having made twenty-seven appearances and scoring once against Blackburn Rovers.
O'Neill has stated that his preference is to play for Australia, but had not been in any contact with Football Federation Australia when he made his Premier League debut in August 2016. He was later called up for an Australia under-23 camp in March 2017. He had previously been contacted by the Football Association of Ireland and the Irish Football Association but reiterated that his preference was to play for Australia.
