To honour the royal visit, the official portrait of the King and Queen by Millie Pilkington was projected onto the sails of the Sydney Opera House.

The late Queen was frequently photographed wearing the brooch, including during her numerous visits to Australia. Queen Camilla first wore the Wattle Brooch for the official photographic portrait taken just before the Royal Tour of Australia.
