Australia's most decorated Olympian, Emma McKeon, headlines a strong line-up at the International Swimming Federation (FINA) Swimming World Cup season's first leg in Berlin, which is set to run from tomorrow until Sunday (October 3).

McKeon had a historic Olympics, winning four gold medals at Tokyo 2020, and will be joined by compatriots Zac Incerti, Matthew Temple, Madison Wilson, Kyle Chalmers, Leah Neale and Minna Atherton in the German capital.

McKeon won seven medals in total in Japan, and now has 11 Olympic medals - more than any other Australian.

Vladimir Morozov of Russia - overall men's Swimming World Cup champion in 2019 - and reigning women's champion Cate Campbell of Australia are both set to compete in Berlin also.

German Olympic champion marathon Florian Wellbrock is due to compete, over 1500 metres, while Arno Kamminga of The Netherlands, South African Chad Le Clos and the United States' Blake Pieroni will all be vying for points also.

Canada’s Olympic champions Kylie Masse and Margaret Mac Neil will also add star power to the three-day meeting.

In total, $1,452,000 (£1,075,000/€1,253,000) in prize money is available during the FINA Swimming World Cup.

Some $224,000 (£166,000/€193,000) will go to the top 20 athletes at each stage and $556,000 (£412,000/€479,000) will be awarded to the top 10 swimmers at the end of the series.

The 2021 Swimming World Cup is set to take place across four legs throughout October.

Hungarian capital Budapest is set to host the second stop from October 7 to 9, while Doha in Qatar is scheduled to stage the third event from October 21 to 23.

Russian city Kazan will hold the final event on October 28 to 30.

All four stops will be contested in 25-metre pools and act as qualifying events for the postponed FINA World Short Course Swimming Championships, set to be held in Abu Dhabi in the United Arab Emirates from December 16 to 21.

The 2021 edition will mark the 18th time that Berlin has hosted a World Cup event, with the first in the 1988-1989 season.
