Australia captain Isaah Yeo says his side has not played to its full potential in the Ashes series, despite convincing wins in the first two Tests against England.
The Kangaroos triumphed 26-6 in the first Test at Wembley, before clinching a series victory with a 14-4 defeat of England at Everton Stadium last Sunday AEDT.
The final Test will be played at a sold-out Headingley in Leeds on Sunday morning AEDT.
Yeo said the Kangaroos were determined to produce a “full 80-minute performance” as they chased a series clean sweep.
“We just haven’t done that yet, but it makes for a wonderful opportunity,” he said.
“England will be all out to make sure it’s not a 3-0 whitewash and we’re trying to make sure it is.

“In the history of the game, you don’t want to lose these things.Â
“This tour’s been truly something special and something we will look back on in our careers and be really fond of having been over here.”
Yeo said England was a far better opponent than the scorelines in the opening two Tests suggested.
“There was a five-minute period there in that second game where it could have gone either way and we were lucky enough to get a couple of tries,” he said.
“There were moments we certainly weren’t at our best, but that was because of the standard they were playing at as well.
“The way they’ve competed through this whole series has been outstanding.”
Yeo has returned to the Kangaroos line-up after missing the second Test because of concussion protocols.
He suffered a head knock early in the Wembley Test a fortnight ago.
Harry Grant captained the Kangaroos in Yeo’s teammate’s absence.
