The team lost to St. Helens. In 2005 the club signed Michael De Vere from Brisbane Broncoes, the highest profile Australian signing since the 1950s. The team finished in 8th place.
2006
In 2006, Sharp led Huddersfield to their first Challenge Cup final in over 40 years, including a 30-12 win over Leeds in the semi finals held at Odsal. Huddersfield lost in the final 42-12 against favourites St Helens.
2007
After a nightmare start to 2007's Super League XII in which Huddersfield lost all of their opening 7 games, some might have expected Sharp's job to be under threat. However, Huddersfield's faith was repaid when Sharp led the team from 5 points adrift at the bottom to being 4th in Super League after, winning a club record 7 along the way including a first win over Bradford Bulls in 35 years. Sharp won consecutive Coach of the Month awards in April and May as a result. The club made their first appearance in the Play Off competition losing to Hull at the KC Stadium, 22-16.
2008
The opening 2 matches in 2008 were lost, to Leeds, and to Bradford Bulls. However the 3rd match saw Sharp's team beat Castleford 64-12. After a 48-0 loss to Catalans Dragons, and a run of disappointing results, Sharp's contract was terminated by Huddersfield and for the 2009 season, Nathan Brown, former coach at St. George Illawarra Dragons, took over the helm. He then moved to Featherstone Rovers in a voluntary advisory role to caretaker coach Danny Evans.
2009
In 2009, Sharp joined his former club Hull F.C. as 'football operations manager', working alongside head coach Richard Agar. However, the partnership didn't work out as Hull slipped to a disappointing 12th-place finish, and Sharp left the club at the end of the year.
2010
In October 2009, Sharp was appointed as first team coach for Crusaders Rugby League, where he will link up with former Great Britain colleague Brian Noble and assistant coach Iestyn Harris.
