[2] Born in Sydney, but grew up in Brisbane, Sean went to the prestigious rugby nursery, St Joseph’s Nudgee College.
Hardman debuted for the Reds in 1999 against the Auckland Blues and has since played over 100 games for the Queensland side.
Hardman has also represented Australia at test, under 21 and A level and was the Wallabies third string hooker at the 2007 Rugby World Cup behind Adam Freier and Stephen Moore.
Hardman would again play for the Wallabies against a second string South African side in the 2007 tri nations, again off the bench and was a surprise inclusion into the Wallabies 2007 Rugby World cup squad as the third hooker as it was expected that either Jeremy Paul or Tatafu Polota-Nau would be chosen ahead of him.
Hardman played one game at the world cup coming off the bench against Canada in Australia's final pool match.
