Witt, along with fellow blue chip signings Ben Kennedy and Brent Kite, added much needed player strength at Manly in 2005 and the club qualified for its first semi finals series since 1998 and finished in eighth position. For the first half of the season Manly was among the dominant teams of the NRL, and Witt's form correspondingly at five-eighth was some of the best of his career to date, prompting Manly officials to publicly thank Parramatta for releasing him. Among the highlights were excellent performances in the victories over eventual Premiers Wests Tigers and in the amazing come-from-behind win against the Penrith Panthers. Penrith led 26-6 early in the second half, before a Witt-inspired Manly team powered home to win 36–26 at Brookvale Oval. Also during this period, Witt kicked 20 successive goals without a miss. However, Manly found wins hard to come by in the second half of the season, and Witt experienced the same frustrations that plagued his 2004. In a match in July against the Wests Tigers, he received a one-week suspension for striking Liam Fulton. And after a disappointing 36–10 loss to the St George Illawarra Dragons a few weeks later, Witt was dropped from the first grade squad after being targeted by the big Dragons forwards due to his perceived defensive deficiencies. Manly coach Des Hasler used a number of forwards at five-eighth in subsequent games, but with very little success, and Witt was drafted back into the side for the semi final against Parramatta. Despite Manly being hopelessly outclassed 46–22 to be eliminated, Witt sent the crowd alight by scoring one of the best tries of 2005, as he weaved through the Parramatta defence and sprinted fifty metres to score under the posts. However, this great moment was marred by yet another two-week suspension, this time for a high tackle on Eels Mark Riddell. Witt was among the leading pointscorers in the NRL for 2005, scoring 140 points from five tries and 60 goals from 19 appearances.
