Bradford Bulls (Super League)
In June 2011, the Bradford Bulls announced that Lulia had signed a two-year contract with the Super League club.
In 2012, Lulia missed the all four pre-season games due to a biceps tear. He also missed the first 2 rounds. However he featured in 25 consecutive games from Round 3 against Wigan to Round 27 against the Catalans Dragons. He also featured in the Challenge Cup against Doncaster and Warrington.
On 18 July 2013, Lulia signed a two-year deal with the Wests Tigers, starting in 2014. He appeared sporadically in first grade in 2014, covering for injured players Chris Lawrence, Tim Simona and David Nofoaluma.
In Round 19 of the 2014 NRL season, Lulia scored four tries against the Canterbury-Bankstown Bulldogs, equaling the club record set by Kevin McGuinness and Marika Koroibete. His coach, Mick Potter, said, "that was a great performance from him. His finishing ability was just second to none. A couple of those tries he scored, not too many people can do that sort of stuff."[4]
In August 2014, Lulia suffered a small vertebrae fracture to his neck and played no further football for the year.[5] He made no first grade appearances in 2015 and was released at the end of the year.[6]
