I don't think even India is actually as good as Australia in the test format to be honest. Because Australia is the best team when it comes to test cricket in my opinion. Of course India wins matches when they play home matches against almost any team. However Australia is probably the only team that has the most consistent performance in the test format against any team and in both home and away matches. And in recent times australia is also playing really well. I personally don't think Australia is actually the most powerful team in the world right now. I think that might be India. But Australia is better when it comes to team performance. And in test format team performance is the thing that counts the most.
Everyone is going with his own method of judgement about teams with overall things are never been on same level like Indians having their own system for going into this and other countries are having their own system of statics recently we have Indians performance was good in Australia, and they won few series as well which is giving good advantage to them but still things are not favorable for them overall because they are having no performance like we have from Australia in all countries which is big advantage for them.
Australians are having world's best system which is giving them players which are able to perform in all conditions and environments and Indians are lacking into this which is surely a problem for them and if we check overall performance then also Australians are best in business.
