Australia 'fell off a cliff' in biggest-ever Test defeat

Joe Schmidt said his Australia side "fell off a cliff" after they gave up a 17-point lead to suffer a humbling 67-27 defeat to Argentina.

Australia suffered their biggest-ever Test defeat on Saturday, as Argentina came from behind to win 67-27 in the Rugby Championship.

And Wallabies coach Joe Schmidt said his team simply "fell off a cliff" after taking a 17-point lead.

Having snapped an eight-game winless run in the Rugby Championship with their last-gasp victory over Argentina last week, Australia were looking to keep the momentum going.

And they looked well set to do just that as tries from Carlo Tizzano and Andrew Kellaway propelled them into a 20-3 lead.

But Mateo Carreras and Julian Montoya, who was playing for Argentina for the 100th time, dragged Argentina back into it and paved the way for Australia's capitulation after the break.

Juan Martin Gonzalez, Joaquin Oviedo, Juan Cruz Mallia and Lucio Cinti all crossed for the Pumas in the second half, with Santiago Carreras' conversion condemning Australia to their record defeat.

"To lead a Test match 20-3 and get run down in the manner which we did is really disappointing," said Schmidt.

"We cannot let a game get away from us like it did and fall off a cliff.

"We lost connection in our defensive line. We were forever chasing them.

"We didn't put enough pressure on at the breakdown, so they were operating off a lightning-quick ball, and it's just too difficult to keep chasing a team on a hot day when they’ve got the ball and going forward."

Australia's previous record Test defeat had come against South Africa in 1997.

Matters do not get any easier for the Wallabies, who now face two matches against Schmidt's native New Zealand as they aim to avoid finishing bottom of the pile.

Second-place Argentina, meanwhile, will tussle it out with Rugby Championship leaders South Africa.
