Not necessarily. In fact, opposition countries have started preparing batting tracks in their home grounds whenever India come because they dont want to face the prospect of the Indian seamers running through their own batting lineup. India's seamers (Zaheer, Ishant, Sree) love pitches with juice in them and come to their own on such wickets. So Aus and SA are not likely to smoke India in their backyard. Our last tour to Australia was a very memorable one, our last tour to Australia got our first win there at Jo'burg and the rest two that we lost, we were not smoked at all.
