The 19-year-old Brisbane-born midfielder joins the League One side from Premier League outfit Burnley.

O'Neill made five appearances for Burnley last season, including his Premier League debut in a 2-0 win over Liverpool. 

He was then sent on loan to Oldham Athletic in January, making 15 appearances for the Latics and helping them avoid relegation from League One. 

“I’m really excited to sign on loan for the season," O'Neill said in a statement. 

"I’m really excited to come here and work under Uwe Rosler and his staff. I want to hit the ground running and do my best to help the team.”

Head coach Uwe Rosler added: “Aiden is a player who we have had on our radar for quite some time. He is 19 years old, but he is far more matured than his age. 

"He will add things to our team what we need, he is athletic, well skilled and we must give compliments to the coaching staff at Burnley for that.

“He is very ambitions, a good lad and I’m delighted to get him to us – I’m sure our department in central midfield will be strengthened. I’m really looking forward to working with Aiden.”
