Australia and the United States will revive the bilateral Duel in the Pool contest after a gap of 15 years in Sydney in August, Swimming Australia announced on Wednesday.
The rivalry between the swimming powerhouses was revived at the Tokyo Olympics last year, where a resurgent Australia ran the United States close in the final medal tally.
The three-day event at Sydney's Olympic Park from Aug. 19 to 21 will bring together 30 Olympic, Paralympic and national team swimmers from both countries, while an open water event will be held at Bondi Beach.
