England head coach Eddie Jones returned serve at Australia's Nic White, who said he was expecting more off-the-ball "niggle" in Saturday's deciding Test in Sydney, describing the Wallabies scrum-half as "the biggest niggler of all time".

With one win apiece both teams are out to secure victory at the Sydney Cricket Ground to decide the three-game series and the preceding two games have set up what should be a fiery encounter.

The Wallabies' Darcy Swain was suspended for a headbutt in the first Test, before cameras caught England prop Ellis Genge driving his elbow into White, as the latter was lying face-down on the ground in the second encounter.

White addressed the situation, asserting that Genge leaning on him was a diplomatic way of putting it, before Jones laughed off his implication about the front-rower.

"He’s got plenty to say. I hardly think he’s entitled to make that comment," the England coach said. "He’s the biggest niggler of all time.

"That makes me laugh. The boy from Queanbeyan who niggles everyone, complaining about niggle. That's a bit like the pot calling the kettle black.

"Obviously he thinks that and his perception is reality, so he's got a funny way of looking at reality. He's just trying to look for something."

Australian captain Michael Hooper cited White's competitiveness to brush off Jones' comments ahead of the Wallabies' captain's run, but added the series had ultimately been played in a competitive but fair spirit.

"Whitey is just obsessed with rugby," he said. "The guy is an absolute footy nerd. He just wants to play. He's as competitive as you'll see. Most half-backs are. He'll be doing his usual thing tomorrow.

"It's been competitive and enjoyable. Both teams just want to win and we get a chance to see that tomorrow.

"[I am] expecting [niggle] to be an element in tomorrow's game but ultimately tomorrow is all about who is up on the scoreboard and who can do it for longer."
