This article details the Cronulla-Sutherland Sharks rugby league football club's 2005 season.
The Sharks started season 2005 brightly; at one stage they were joint ladder leaders after round 11.
However, the season would fall apart with losses to Parramatta at home (the Sharks trailed 22-0 at halftime before rallying in the second half to go down 34-26), North Queensland in Townsville, the eventual premiers Wests Tigers at Campbelltown in round 14 before winning against the Sydney Roosters at home in round fifteen.
The Sharks' round two loss to the Manly-Warringah Sea Eagles was marred by the sickening injury suffered by Keith Galloway as a result of a high elbow shot from Manly winger John Hopoate.
For his part, Hopoate was sacked by the Sea Eagles after receiving a mammoth 17-week ban by the NRL Judiciary.
