By Justin Langer Australia Test batsman

Having already won the Test series in South Africa, this final match of our tour in Johannesburg still has special significance.

We understand this will be our final true test before England arrive in Australia towards the end of the year and we want to keep getting better and better for that contest.

It is also my 100th Test match, so from a personal point of view it will be nice to celebrate this feat, of which I am proud, with another victory.

The taste of success is not only pleasurable, it is also addictive. So the match starting on Friday will be another opportunity to enjoy that habit of success.

Memories are still fresh of our victory in Durban with only a handful of overs remaining on Tuesday.

The celebration as Shane Warne dismissed Makhya Ntini pretty well said it all.

As the umpire's finger moved towards the sky, 10 Australian cricketers chased Warney out to deep midwicket to form a triumphant huddle.

After a nerve-racking fifth day, the relief and joy of a job well done climaxed in an excited war cry of emotion.

Rarely do you see the Australian team so fired up by a Test victory, but in this case the series-sealing victory was one that meant a lot to this touring party.

There has been a lot of talk since South Africa arrived in Australia in November. And now, after five tough Test matches, we have proved what a good side we are in all conditions.

On the final day in Durban we needed all 10 wickets to win.

We had to contend with an increasingly flat and lifeless pitch. Then, there was the talented South African batting line-up to deal with, followed by the uncontrollable factor of the inclement weather.

Throughout the game, rain and more particularly bad light had played a significant role.

Fortunately, though, we have the unbridled advantage of Shane Warne in our team, so that when the umpires declared conditions unfit for fast bowling, our leg-spinning genius was able to keep the pressure on the Proteas at all times.

After the first hour, the South African batsmen looked relatively comfortable at the crease and it felt like we would be in for a tiresome day and a drawn cricket match.

However, as we have seen so many times before, Shane's first spell turned the game on its head.

He ripped through the South African top order to give us the momentum, and then added the final two wickets in the last session.

Ricky Ponting, meanwhile, is a batting genius with a gift reserved for a few.

His centuries in both innings took his overall count in Tests to 30 and considering he has many years left in him, he could end up as the greatest run-scorer of all time.

Brett Lee took his 200th Test wicket - his six wickets part of an outstanding team performance where every single player contributed to the final result.
