It was the first time that the Proteas went into battle with eight players of colour - the most ever in a senior cricket match.
For people in the media and in the public who say that transformation weakens our national sports teams, this was a bloedneus.
There were great performances from Farhaan Behardien, Kagiso Rabada, Wayne Parnell, Imran Tahir, Aaron Phangiso and debutant Tabraiz Shamsi.
And at a ground where the Proteas lost to the West Indies by four wickets last Friday, with spin bamboozling them, they managed to bounce back.
They showed fighting spirit against an Australia side at the top of their game after winning the World Cup last year, and still leading the rankings.
This was by far the most representative side the Proteas have ever put out and it will give mense believe that the excellence in black players is far from the being just the exception.
Many times black players are distrusted for being less professional, that they cannot handle the pressure.
This has blown those stereotypes out of the water.
And, yes, it was just in a tri-series tournament. But SA cricket has been in a slump for over a year and victories to be proud of have been few and far between.
If the side is in a transitional phase, then this is a signpost on the way to go.
I’m not saying that the team has to be completely cleared of whites, but black talent is every bit as valuable as white talent and should be picked on merit.
And what better yardstick than to beat a champion Aussies side to prove that you are up to the job.
Cricket South Africa, of course, are still in a shambles where the national teams are concerned.
They could never make the review with Francois Pienaar happen. to get down to the problems that they have. But it seems like the team management has learnt some lessons and made some bold moves.
The spin trio and the left-right seam combination worked a treat against the Aussies.
Those variations kept the Aussies guessing and gave each bowler his due to do his own thing.
That’s how you get a Protea fire going.
