Australia expect England to hit them with "rough" tactics in Saturday's World Cup quarter-final showdown in Marseille.

John Connolly, the Wallabies head coach, fears England will try to unsettle his side and urged referee Alain Rolland to clamp down on anything underhand

Connolly also revealed that he has met with Paddy O'Brien, the International Rugby Board's referees' chief, and raised specific concerns about England hooker Mark Regan.

"England picking Regan at hooker delivers an intent," he said. "We've spoken to Paddy O'Brien to ensure he behaves himself, just to ensure the game's fair and clean."

Jake White, the South Africa coach, recently accused Regan of not throwing straight down the middle of the lineout and of stepping into the field of play, which is understood to have been one of the issues raised by Connolly.

After England's second Test defeat to South Africa in the summer, hooker John Smit remarked that Regan had "said more to me in two games than my wife has in 10 years".

Regan was also admonished by referee Rolland for overstepping the mark as he celebrated England being awarded a penalty during their defeat to France in Marseille in August.

Michael Foley, Australia's forwards coach, is concerned his players do not react to any chat or dirty tactics from the England forwards. The Wallabies to not want to gift Jonny Wilkinson shots at goal but Foley has warned them what to expect.

Replacement lock Hugh McMeniman said: "Foley has coached some of the boys and he says they're pretty rough. You can expect anything from the English really, definitely off the ball stuff and anything if you are lying on the ground; a bit of the scratch on the eye, but all the boys have coped with that before. It's not going to have any effect on us.

"I would like to see us play the sort of game we want to play, I get more enjoyment out of that than coming down to fisticuffs on the ground with some blokes. There's a lot of teams in the world that do it to try and get over the top of their opposite player mentally."

Number eight Wycliff Palu impressed the need for discipline, even if England are looking for a rise.

"There'll be plenty of niggle. The team that controls their discipline will get over the top," he said. "You've just got to control yourself and get them back some other way - a big tackle or something. If you give away a silly penalty, especially with Jonny Wilkinson playing, you give away three points."
