Puberty Blues is a 1981 Australian film directed by Bruce Beresford. The film is based on the 1979 novel Puberty Blues, by Gabrielle Carey and Kathy Lette, which is a protofeminist teen novel about two 13-year-old girls from the lower middle class Sutherland Shire in Sydney, Australia. The girls attempt to create a popular social status by ingratiating themselves with the “Greenhill gang” of surfers.
