The Queen Park Rangers striker, who is on loan from West Brom, said he and teammate Geoff Cameron came to blows following Rangers’ defeat at Birmingham on Saturday.
Austin gave the west London side the lead just before half-time before two quickfire Birmingham goals late in the second half saw QPR leave empty-handed.
The result understandably left the QPR players seething but the anger threatened to spill over in the away dressing room afterwards with Austin and Cameron engaged in a spat.
But the situation was diffused by Stefan Johansen, who apologised to the whole team for missing a big chance when QPR were 1-0 up.
Austin told Drivetime: “Me and Geoff Cameron, after the game, had a little moan at each other. He came in saying it wasn’t good enough, I replied that we gotta defend better.
“We have a full argument in front of the team and then Stef stood up and said ‘woah, woah, woah, it’s my fault, I should have killed the game off. It was poor from me’.
“Me and Geoff just looked at each other and went ‘I’m glad he just said that!’.
“It depends on the player. Stef’s Norwegian captain, should have scored to make it 2-0 and he knows that, he stood up in front of us and held his hands up.”
Austin says the issues have now been resolved but believes the fact that he and Cameron were arguing is a good sign for the club’s future.
He added: “It’s the sign of a good team because you want the best for each other. There’s a fine line, of course there is, but the best teams will argue for sure.”
