Mollie O'Callaghan will spend the next four years sucking up the disappointment of missing a medal in the 100m freestyle at the Paris Olympics.
O'Callaghan, suffered anxiety ahead of Wednesday night's medal race, finished fourth.
The 20-year-old clocked 52.33 seconds, some 0.18 behind gold medallist Sweden's Sarah Sjostrom.
"It's not a great time," O'Callaghan said.
"I expected a lot more. But at the end of the day, you've got to suck it up and wait another four years."
O'Callaghan admitted to being overcome by nerves despite already having won gold in Paris in the 200m freestyle and with her Australian teammates in the 4x100m freestyle relay.
"I was really nervous heading into this, didn't have a lot of sleep over the past few days," she said.
"I tried really hard to manage myself and get up for this.
"But I knew the 100 free was going to be hard because it's a lot about speed and that's something I really lack in.
"I knew it as going to be a tough race ... if you stuff something up, it costs you."
O'Callaghan's compatriot Shayna Jack, who watched the Tokyo Olympics three years having just finished serving a two-year doping ban, was fifth in 52.72.
