Aus record lately on any track that swings or seam doesn't inspire confidence either.If SA is planning on serving sporting tracks then 5 bowlers are completely unnecessary. They will get hammered against team like Australia who are used to these conditions much more than Indians are.
Both sides batting is vulnerable. SA has the superior bowling attack. Aus has a good attack no doudt but kg,philander, Steyn, Maharaj & morkel/ngidi is as good as you get currently.
If SA can contain Smith they have a great chance.
