Captain Tim Paine admitted he'd never experienced a match like it, after Australia lost the third ODI to England by 242 runs.
England secured their biggest winning margin in an ODI at Trent Bridge, and in doing so took an unassailable 3-0 lead in the five-match series.
New skipper Paine used eight bowlers in the game to try to find a way to stem the flow of runs, but only spinner Ashton Agar was spared.
Agar went at seven runs an over in his 10-over spell, while four of the bowlers had economy rates into double figures.
England were spearheaded by centuries for Jonny Bairstow and Alex Hales, and were 310-1 at one stage.
Paine admitted after the match he'd found it a tough experience against a batting side he said had struck the ball as well as he'd ever seen.
"I've just said in the changing rooms, I've been playing cricket since I was a kid and that's the hardest day's cricket I've ever had in my life," he said.
"Everything we tried didn't work and everything they tried came off. Normally that happens for an hour or two and you get a couple of wickets but it happened for as long as it did."
Paine didn't rue electing to field after winning the toss, saying the reason for the defeat was that Australia had run into a team with red-hot players.
Now the series is lost, Australia are set to continue to tinker with their batting line-up as they try to fill the significant holes left by the absence of Steven Smith and David Warner.
"The best place for these guys to learn is on the job," said Paine.
"So as bad as it feels right now this can be a big positive for us going forward that we've gone through a day like this and the guys realise that the sun comes up tomorrow and we get another crack at it in two days' time."
