Matthew Denny and Nicola Olyslagers have broken their own Australian marks on a remarkable record-setting day of track and field at the Diamond League final in Eugene.
Denny made up for the disappointment of finishing a close fourth at the recent world championships by winning the Diamond League discus crown on Sunday (Monday AEST).
The big Queenslander's best throw of 68.43m came in the final round as he relegated 2022 world champ Kristjan Ceh from Slovenia and Sweden's reigning Olympic and world gold medallist Daniel Stahl to the minor placings.
"I'm very happy with this today and it's a great way to end the year," said Denny, who added 19cm to the national mark he set last month in Budapest.
"I thought I was in good nick but it was good to connect and put it together on the last meet of the year when a lot of other people might be fried or over this season.
"I was pretty keen to make amends for Budapest, so I'm happy with that."
Not to be outdone, world championships high jump bronze medallist Olyslagers dug deep with a last-attempt clearance at 2.03m, which was 1cm better than the Australian mark she had previously shared with her great domestic rival Eleanor Patterson.
Ukrainian star Yaroslava Mahuchikh pipped Olyslagers on countback, adding the Diamond League title to the world championships gold she won in the Hungarian capital just a few weeks ago.
"I'm feeling really thankful of the year that's been and the personal best was always the plan this year," said Olyslagers.
"To do it on my final competition was a blessing."
While Denny and Olsylagers were re-writing the Australian record books, Swedish pole vaulting supremo Armand Duplantis and Ethiopian distance running superstar Gudaf Tsegay were setting new global marks.
Duplantis was again in a class of his own, setting a seventh world record with a successful clearance at 6.23m.
"I don't remember the jump. I'm dead serious ... I just knew that it was going to be really close," he said.
"I knew that when I was over the bar just to not panic because I knew I was going to have to squeeze over a little bit."
Australian world championships bronze medallist Kurtis Marschall was fourth (5.72m).
Earlier in the day at Hayward Field, Tsegay smashed the women's 5000m world record with a landmark run of 14 minutes 00.21 seconds, breaking Kenyan Faith Kipyegon's previous mark set in June.
Tsegay set a blistering pace from the start and broke away from the field with two laps to go, rousing the fans to their feet as she raced against the clock.
The world 10,000m champion took almost five seconds off the world record that Kipyegon set at the Paris Diamond League meeting as part of a record spree that also saw the Kenyan set global marks for the 1500m and mile.
Consistent Australian Brooke Buschkuehl (6.71m) was fourth in a women's long jump competition won by Serbian world champ Ivana Vuleta (7.14m).
Catriona Bisset was sixth in the 800m and Stewart McSweyn was eighth in the 3000m.
