South Africa captain John Smit accepted there was plenty for his side still to work on following their 44-31 Tri-Nations victory over Australia in Pretoria.
The Springboks ended a run of four defeats to clinch a first win in the competition and climb to second in the standings behind already-crowned champions New Zealand.
"The second half was a little bit closer to what we want. But after the start we had, we know we definitely need to tighten up - that really complicated matters," said Smit. "We wanted a lot more accuracy and it came after the first 15 minutes, but that is not the type of rugby that will win you the World Cup."
The start he was referring to was the Wallabies snatching a 14-0 lead inside the first five minutes.
It was a dreadful start and one that Smit was not proud of, but he felt happy with the spirit shown by his players.
"Coming back from being 14-0 down and the game had barely started is something we can be proud of, but it's obviously not something we wanted to do," he added.
"I told the guys that we still had 70 minutes left and there was plenty of time to win this game, and we started to do things better.
"We held on to the ball more, kept it in hand and got the set-pieces working.
"In the four weeks since we got back (from Australia and New Zealand), we worked on correcting the errors that had crept into our game and got back to basics."
