Australian Prime Minister Julia Gillard was joined by U2 frontman Bono at a ceremony to mark World AIDS Day in Sydney Tuesday.
The event saw the Sydney Opera House and Harbour Bridge bathed in red lights, the Australian Broadcasting Corp. reported.
Standing on the stage with Australia's first female prime minister, Bono joked he felt like Charlie from the 1970s U.S. TV show "Charlie's Angels" "surrounded by powerful women." He went on to call for an "AIDS-free generation starting in 2011."
Gillard paid tribute to the Irish rocker and social activist, saying he has "a message of hope for AIDS sufferers".
"There is also a sense here in Australia and other developed nations that the prevention message is being lost as new generations grow up and
complacency sets in," she said.
The Sydney landmarks join a number around the world to be transformed for the day, including New York's Empire State Building, the Hotel de Ville de Paris in France and the London Eye.
