A new Group One sprint for three-year-olds will be introduced at the Royal Ascot meeting.
The 1200m race, to be called the Commonwealth Cup, will replace the Buckingham Palace Stakes on the Friday card.
Ascot chief executive Charles Bennett said they were hoping to eventually attract the best two-year-olds from Australia.
"Longer term we are looking to attract interest from connections of horses that have run in championship two-year-old races in Australia like the Blue Diamond and the Golden Slipper, as they are counted as three-year-olds in the northern hemisphere at Royal Ascot," Bennett said.
"We are very excited about the Commonwealth Cup, which has already been talked of in positive terms by the connections of this year's leading two-year-old filly, Tiggy Wiggy, and American-trained Hootenanny, who won the Windsor Castle Stakes at this year's meeting and was subsequently successful at the recent Breeders' Cup."
