[3] Lette first attracted attention in 1979 as the co-author (with Gabrielle Carey) of Puberty Blues, a strongly autobiographical, teen novel about two 13-year-old southern suburbs girls attempting to improve their social status by ingratiating themselves with the "Greenhills gang" of surfers.

[9][10] She teamed with Radox to write a water-resistant book, which was released free online in September 2009, with an aim to encourage women to be selfish with their time.

In recognition of her many novels and advocacy of equality, human rights, and physical and mental health both nationally and internationally, Lette was awarded an Honorary Doctor of Letters (Honoris Causa) from the University of Wollongong on 20 April 2017.

[15] In August 2014, she was one of 200 public figures who were signatories to a letter to The Guardian expressing their hope that Scotland would vote to remain part of the United Kingdom in September's referendum on that issue.
