Beating the Australians in their own backyard is as good as lifting the World Cup, says South African all-rounder Jacques Kallis [Images], who rates the Test series triumph as the highest point of his career. 

"It is up there with winning the World Cup, if not better. What better place do you want to do it? I have had some individual high moments here but ... this takes the cake, having won a Test match here," Kallis was quoted as saying by The Australian.

South Africa [Images] has sealed the three-match series after winning the first two Tests in Perth and here, humbling the Aussies at home for the first time in 16 years. 

Kallis, who scored two half centuries in the opening Perth Test, said playing and winning Down Under is one of the toughest challenges that a cricketer can imagine. 

"All the younger generation, I don't think they appreciate just how tough a place Australia [Images] is to tour," he said.
