Can India's performance in overseas tests improve from what its been in the last 4 years?

The last 4 years have been good no doubt with series wins in England,West Indies and New Zealand. Do you think the team can take it to the next level and win in Aus and SA? They did well the last time they went to SA by winning the first test at Jo'burg but couldn't quite force the issue. The same goes for the last 2 tours of Australia(2003-04 and 2007-08). Can they do it this time around?
