Hallworth began his career as a trainee at Ipswich Town before signing a professional contract. During his time at the club he spent time on loan at Swindon Town, Bristol Rovers, where he made his professional debut, and Fulham before returning to become first choice goalkeeper until he was displaced by Craig Forrest.
In 1989, he joined Oldham Athletic in a deal worth £75,000. He went on to spend the majority of his career at Oldham and was the club's first choice goalkeeper for most of his eight years there. He helped them reach the FA Cup semi-finals and the Football League Cup final in his first season, promotion to the First Division after a 68-year exile in 1991 as Second Division champions, and to another FA Cup semi-final in 1994. In both FA Cup semi-finals, the Latics held Manchester United to a draw before losing in a replay. He also helped the Latics survive three years in the top flight (FA Premier League from 1992) before relegation in 1994.
He left the club in 1997 to sign for Cardiff City on a free transfer. He was first choice goalkeeper for three years before being replaced by Neil Alexander. He left the club in 2001 and went on to play for fellow Welsh clubs Newport County and Bangor City.
