During the ceremony, William signed the book of remembrance to a backdrop of Didgeridoo music.
Tensions between the once-close brothers are believed to have hit rock bottom, particularly since the release of Harry’s memoir in January.
News Corp Columnist Angela Mollard told ‘The Royal Report’ show on Sky News Australia that Harry and William’s relationship is “just on its knees”.
Mollard added that she doesn’t believe the brothers will “exchange a word” throughout the entire Coronation.
