The 2005 OFC Club Championship was the 4th edition of the top-level Oceanic club football tournament organized by the Oceania Football Confederation (OFC), and the 1st since 2001. The tournament was held in Papeete, Tahiti. The preliminary rounds were played from 10 February until 6 April 2005, with the finals beginning on 30 May and ending on 10 June 2005.
The tournament was initially planned to take place in September 2002, in anticipation of the upcoming FIFA Club World Championship in the following year, in order to decide which team would represent Oceania at the tournament. However, this tournament was cancelled, and therefore so too was the Oceanic competition. With the return of the tournament in 2005, the OFC Club Championship went ahead, and the winner went on to represent Oceania at the 2005 FIFA Club World Championship.
A preliminary round was held, with the format being a two-legged playoff to determine who went through to the final round. The Australian representative (Sydney FC), as the representative of the strongest OFC Nation, and the two Tahitian Teams (AS Pirae and AS Manu Ura), as hosts, were seeded to the main draw.
The travelling team played two matches in the host country. The aggregate scores are shown.
The eight remaining teams were separated into two groups, each team playing the other teams once. The top two teams from each group progressed to the semi-finals.
^Manumea was withdrawn by the OFC, due to administration concerns from the American Samoa Football Association and not guranteeing the facilities and infrastructure to host an international match.[1]
