South Africa skipper Graeme Smith has labelled his team's second successive series win in Australia as the proudest moment of his decorated test career.
The Proteas wrapped up a 1-0 series triumph over Australia and retained the No 1 test ranking with a crushing 309-run victory in the third Test at the WACA Ground.
Four years ago, South Africa notched their first ever series win in Australia when they posted a 2-1 triumph.
But making their latest success even more sweeter is the fact it came on the back of a 2-1 series win in England, with South Africa not losing a single test in 2012.
"I'm extremely humbled. For us it means the world," Smith said.
"There's still people involved that have taken many beatings on tours of Australia.
"For us to win back-to-back series in England and Australia is an immense effort.
"To come here, and do it (win the series) twice in a row, for me, it's the proudest achievement of my career."
South Africa were on the back foot for much of the opening two tests, with their effort to draw in Adelaide particularly special.
Smith praised the fighting spirit of the team, and commended the way they continually overcame seemingly hopeless situations.
"It hasn't been the perfect series," Smith said.
"In England, everything went according to plan. Here we had to scrap and adapt. We had injuries. Our depth was tested. It's a great sign that will still came through.
"And at times we haven't bowled well. But we certainly hit our straps in this Test match.
"This is the performance that I've got used to from our guys over the years. It's important not to take it for granted, because it was outstanding."
The Proteas will be aiming to extend their 10-Test unbeaten run when they play a two-match series against New Zealand in South Africa in January.
