De Waart became chief conductor and artistic adviser of the Sydney Symphony Orchestra in 1993, and served in the post until 2003. While in Sydney, De Waart made no secret of his dislike of the acoustics of the Sydney Opera House Concert Hall, the orchestra's home, saying, "if there is no clear intention to do something to improve the hall, then we really seriously have to look at another venue". In 2004, De Waart became artistic director and chief conductor of the Hong Kong Philharmonic Orchestra. He concluded his Hong Kong tenure in 2012.
