Australia's Zac Stubblety-Cook has set a world record for the 200m breaststroke at the national championships in Adelaide.
Stubblety-Cook clocked two minutes 05.95 seconds in Thursday night's final.
His time bettered the previous world benchmark of 2:06.12 set by Russian Anton Chupkov in 2019.
"It's a bit surreal to be perfectly honest, it doesn't feel real," Stubblety-Cook said.
"It will probably sink in over the next few days.
"I was obviously hoping to swim fast and hoping to swim close to my best but that is just something else."
The 23-year-old from Brisbane won gold in the same event at last year's Tokyo Olympics.
But while he'd fleetingly thought of breaking the world record, he said it wasn't on his radar entering the Adelaide meet.
"I had thought about it ... but I never have been like 'yes, that's it, I want to break the world record'," he said.
"It happened obviously ... but I didn't think we were going that fast."
