Paul signed for Warrington RLFC as a fourteen year old schoolboy from his junior club Waterhead ARLFC in Oldham. Reaching his early potential he made his Great Britain debut as an eighteen year old on the 1996 Oceania Tour to PNG, Fiji and New Zealand.
In 1998 Scully signed for St Helens RLFC in a world record transfer for a forward for £375,000 aged nineteen. This was to be a move that paid great dividends to both Paul and Saints as they went on to be the most successful team in the Super League era. During this time Scully was twice named Man of Steel (2001, 2002), still the only player ever to retain the award in consecutive years.
In 2004 Scully was named Saints skipper and in 2005 as many predicted, he was named Great Britain captain. In 2008 after two years of a horrendous run of injuries, Scully decided to hang up his boots and look towards the next chapter of his life. He now concentrates on his Paul Sculthorpe Rugby League Skills & Development in an aim to get more people involved in the great game of Rugby League. Alongside inspiring and entertaining people on the After Dinner Circuit at numerous Sportsman's Dinners and such events.
'Just to let you know that Paul Sculthorpe and Pete Emmett were absolutely brilliant at the luncheon, especially their double act. The York crowd are so good and appreciative and I gather that both Paul and Pete enjoyed their visit. I feel sure that John Duck will give you some feedback as well but if you are in touch with either of them, please give them my personal thanks.'
