Young sprint gun Torrie Lewis and established middle-distance star Jessica Hull have backed up to complete historic multiple triumphs on the final day of the 100th edition of the Australian track and field championships in Brisbane.
Lewis, 18, even shocked herself by the way she was able to recover from Saturday's breakthrough 100m victory to claim the 200m title in a personal best of 23.02 seconds.
Ella Connolly (23.16) and Riley Day (23.24) rounded out a Queensland trifecta.
Not to be outdone, Hull ran solo at the front to win the 5000m title in 15:05.87, a day after she saluted in the 1500m.
The 26-year-old also won the Australian 3000m championship last month in Sydney, making her the first Australian woman to hold all three titles simultaneously.
Only Glenys Beasley back in 1962 had done the Australian sprint double at a younger age than Lewis.
"It was way more than I could have expected," she said.
"To be honest I came in with high hopes for the 100.
"But the situation wasn't the best coming into the championships and for the 200 I just didn't really feel fit enough.
"So to come in and win, especially with the back-end strength, I'm pretty happy."
Lewis's surprise victory in the half-lap race could force a rethink in her priorities in the buildup to August's world championships in Budapest.
"Yesterday I would have told you the 100 was the main target for sure," she said.
"Now it's a case of whatever on the day.
"It's a surprise for me and for you and then there's always the relay too."
Lewis did not get the best of starts in Sunday's 200m final but she made up for that with a powerhouse finish as she stripped four-hundredths of a second off her personal best.
"I was that close to going sub-23," said Lewis.
"Hopefully this is the season to get it."
Hull had a crack at the tough world championships 5000m qualifying standard but realised it was out of reach with 1000m to go.
"Being able to do that time solo today does give me a lot of confidence that I can hang in there in Budapest (if I contest the 1500m and 5000m)," she said.
"It's been a great weekend and a really productive one."
Queenslander Callum Davies also did the 1500m-5000m double - stopping the clock at 13:52.82 in the men's longer race on Sunday.
Two-time Commonwealth Games pole vault champion Kurtis Marschall was lucky to escape serious injury when he snapped his pole while attempting what would have been an outdoor PB of 5.90m.
Marschall wisely decided to call it a day, having already claimed the national title with a best clearance of 5.80m.
Ultra-consistent Catriona Bisset set a championships record of 1:58.32 to win the women's 800m.
The race came at the ideal time for the Victorian, who is back to full fitness after suffering a minor hamstring injury earlier this year.
Michelle Jenneke also locked in her spot for the world titles in Budapest by claiming a second national title in the 100m hurdles in 12.77.
It was the fifth time the 29-year-old had dipped under the automatic qualifying standard of 12.78.
Tokyo Olympics silver medallist Nicola Olyslagers won the women's high jump with 1.95m and Jake Doran took gold in the men's 200m in 20.81.
