Australia broke with tradition to hold its swimming trials just six weeks before the start of the 2020 Olympics and former world champion Giaan Rooney said the move could reap rich rewards in Tokyo after disappointments at London and Rio. Australia has typically held its trials up to six months before an Olympics but that gap has been drastically cut this year with swimmers vying for Tokyo spots this week in Adelaide. Rooney, who won individual world titles at Fukuoka and Montreal and a relay gold at the 2004 Athens Olympics, said Australia is gearing up for a much improved Games after its swimmers flopped at Rio and London.
