SA view: Australia's weak spot at No.6, Proteas weak spot is playing at home against Aussies George Bailey averaged 26.14 in his debut Test series. AUSTRALIA beware - South Africa has worked out your weakness. There is genuine wariness in the Republic, mixed with a tinge of disbelief, about Australia's resurgence as a force in Test cricket ahead of its battle with the Proteas next month. While some scoffed at Michael Clarke's suggestion that he possesses the best bowling attack in Test cricket, given the top-two ranked bowlers in the world are both South African, the Proteas couldn't help but sit up and take notice of Mitchell Johnson's blistering Ashes form. But another aspect of Australia's play that didn't go unnoticed was the fragility in its batting line-up, and in particular the troubles experienced by Test debutant George Bailey. Bailey was the only member of the Aussie Test line-up not to make a century this summer, and finished his first Test series with a disappointing average of 26.14. "All of the Australian team, pundits and public are notably bullish again after their 5-0 Ashes thrashing of England ... but No 1-ranked South Africa are fully aware of where their weakest spot still lies," Rob Houwing wrote for the Sport24 website. Little wonder that when shrewd critic and former Test batsman for both nations, Kepler Wessels, spoke to Sport24 a few days ago he said: 'There are still some holes in their batting ... and (especially) Bailey at No 6.' All right, you got us, we've got a weak spot at No.6. But the joke's on you, South Africa, because you've given up what your weakness is too. Playing in South Africa. No, that's not a typo - the Proteas do indeed have a worryingly poor record on home soil when taking on Australia. Amazingly, the Aussies are yet to lose a Test series on African soil since the Proteas were brought back into the international arena in 1993 at the end of apartheid, winning four series and drawing two. To put that achievement into perspective, South Africa has only lost one other home series during that period, against England in 2004-05. It's a fact that has led many to predict Australia will experience some level of success against the Proteas despite their No.1 ranking and their win over the Aussies in the teams' most recent meeting in 2012. And ex-Test batsman Ashwell Prince has warned his former teammates not to let their guard down against the Aussies - something South Africa did in 2009 after achieving a historic victory Down Under just a few months earlier. "There was a lot of emphasis placed on the fact that we hadn't won there before, and that probably had a positive influence on our preparation," Prince told Johannesburg's The Times. The away series had probably taken too much out of the guys, and they might have relaxed when they played the home series. In injury news, world No.1 batsman AB de Villiers will undergo surgery this week but is expected to be fit in time to take on Australia. The Proteas wicketkeeper is set to go under the knife on Friday to have a plate removed from his hand, but team management is confident he will recover within three to four weeks.
