Japan's stunning upset of South Africa is proof the gap is closing between the haves and the have-nots, further emphasising why the Wallabies won't take Fiji and Uruguay lightly.
At the World Cup, any game is a potential banana skin.
Wallabies coach Michael Cheika says his squad, who face Fiji in their opener in Cardiff on Thursday morning, before backing up against Uruguay on Sunday, won't make the mistake of letting their thoughts wander to the big Pool A matches against England and Wales which follow.
"What we saw [from Japan's win] is if you take your eye off the ball for a minute, you will get pounded," Cheika said. "I am certainly not going to take my eye off the ball. That's the thing about rugby, it's a very humbling game.
"You do well in one scrum and you knock off in another and you'll get turned up; you carry strong once but if you don't carry strong the next time someone will pick you up and dump you."
