A $20,000 fine for five breaches of the NRL media policy has taken the total value of fines imposed on Canberra mentor Ricky Stuart to $125,000 during his coaching career.

Stuart was hit with his 10th fine from the NRL after walking out of the post-match press conference after last Saturday night's 24-12 loss to Brisbane over what he later claimed was a build up of frustration with the performance of referees in recent weeks.

He also withdrew from a halftime interview with the host broadcaster Fox Sports, which he had agreed to do before the match, and refused to allow any Raiders players to speak to the media afterwards.

A radio interview Stuart conducted mid-week, in which he outlined the reasons for cutting short the press conference after 24 seconds, was also deemed to have been a breach of the NRL rules about comment on referees.
