Kaiser Chiefs made their Oxegen debut on the Main Stage.

Kaiser Chiefs made their Oxegen debut as the third act on the Main Stage on the Saturday, a feat they would surpass on the Sunday of the following year when they were third headliners. They later went on to become second headliners on the Sunday of the 2008 festival. Other bands to make their Oxegen debut included Bloc Party, The Bravery and Rodrigo y Gabriela.^[16] Bloc Party frontman Kele Okereke received a cold reception from the crowd after saying that it was great to be "back in the UK" before trying to back out of it by saying that he meant "familiar territory".

Audioslave played on the Main Stage on the Sunday of Oxegen 2005, their only Irish festival performance before their split in 2007. They performed much of their own material and also previous songs by Soundgarden ("Spoonman" and "Black Hole Sun") and Rage Against the Machine ("Killing in the Name"). The band minus Chris Cornell went on to headline Oxegen 2008 with Zack de la Rocha as the reformed Rage Against the Machine, with "Killing in the Name" performed in its original style.^[17]

The scheduled appearance of Bright Eyes in the Green Room on the Saturday was cancelled at the last minute; they were replaced on the bill by Irish band 66e who were asked to step in on that same afternoon. Bright Eyes did however later go on to make an appearance on the Pet Sounds Stage on the Sunday of the 2007 festival. Ian Brown headlined the Green Room on the Saturday of Oxegen 2005 before going on to repeat this on the Sunday of Oxegen 2008. Flogging Molly performed in the Green Room on the Saturday of Oxegen 2005 before oddly going on to perform on the New Band Stage on the Sunday of Oxegen 2008.

The Magic Numbers, Future Kings of Spain, The Go! Team, Humanzi, Director and The Blizzards were amongst the bands that performed on the New Band Stage. Editors too performed on the New Band Stage, making the first of what, as of 2008, was four consecutive appearances on four different stages at Oxegen. They performed on the NME Stage in 2006, the Green Room in 2007 and the Main Stage in 2008.

Health

The Order of Malta had 70 personnel and ambulance crews on site to deal with any problems in the arena over the weekend, while Civil Defence provided over 120 personnel and emergency vehicles for the campsite.

Crime

Dozens of gardaí, drug enforcement officers, sniffer dogs and security officers policed the grounds.^[18] There was no serious trouble with less than 100 arrests for drug offences, generally for possession of cannabis.
