[4][5] After graduating from university McClymont worked for a publishing company and then the Australian Caption Centre; in 1985 she applied for a job at The Sydney Morning Herald.
Her experience in the busking booth at Kings Cross impressed the editors and she was one of 30 from 1,200 applicants to secure jobs at Fairfax Media publications.
[2] McClymont was sent to The Eastern Herald as a cadet reporter[citation needed], and while there she covered the wedding of a relative of crime boss George Freeman.
[2][5] McClymont left The Times on Sunday for the Australian Broadcasting Corporation's Four Corners program as a researcher for two years,[1][5] before returning to The Sydney Morning Herald in January 1990.
The investigation by the Australian Jockey Club (AJC) stewards that followed found Cassidy guilty of "improper conduct, in that he falsely and fraudulently told a punter that horses had won races as the result of a fix and that he made an arrangement with Moses to corroborate his story".
The Walkley Advisory Board judges said "Davies' and McClymont's investigation was an impressive piece of journalism that would have a permanent impact on the administration of professional sport in Australia.
[10] Former HSU Secretary and federal Labor Party politician Craig Thomson was also named and was initially sentenced to 12 months gaol, which was reduced to a $AU25,000 fine on appeal.
[11] In 2017 McClymont led a joint ABC – Fairfax investigation into Australian television personality Don Burke with journalists Tracey Spicer, Lorna Knowles and Alison Branley.
[3] McClymont's reporting initiated a number of Independent Commission Against Corruption (ICAC) and investigations during her career; the most notable was Eddie Obeid,[4] a former New South Wales Labor party power broker and politician who was sentenced to five years' imprisonment in 2016 for misconduct in public office.
[15] McClymont first wrote about Eddie Obeid in 1999, and since that time she has received information, from a variety of sources, about his corrupt activities which has enabled her to write a series of articles and a book about him.
