The Wallabies have not claimed a grand slam sweep of the Home Nations in 29 years and a dismal three-from-10 win record this year does not augur well for this attempt.

Former captain Nathan Sharpe and World Cup-winning coach Bob Dwyer both believe the Wallabies can be successful on the tour but only if the Wallabies clean up their handling and coach Ewen McKenzie finds the right combination in the back row.

''I definitely think it is possible but, at this stage, I'm not sure that it's probable and they are going to have to be far more clinical getting out of their own half, especially in the northern hemisphere,'' Sharpe said.

''I like the mindset to attack they have but, until their last couple of games, they've made too many errors in turnovers and breakdown work. If they continue with their strategy but don't execute with precision, then they'll find themselves in trouble because these northern hemisphere teams play a field position-oriented game.''
