Nemanja Vidic has insisted that Serbia will take nothing for granted against Australia.
Serbia's shock win over 10-man Germany on Friday has handed them a chance of progressing from Group D.
Their final group clash is versus the Australians, who were heavily beaten by Germany in their opening fixture.
Centre-back Vidic, though, has stressed that his team-mates will be wary of complacency in Nelspruit.
The Manchester United player said: "They had a bad game just like we had against Ghana. You can't judge a team on one match.
"All the teams who are here at the World Cup have good qualities, it's only small details which decide who is going to win.
"We respect Australia, they have four or five players who play in England at a high level.
"That says something about the team. I'm sure it will be a difficult game."
