5. 161 against South Africa 2014
This was the match in which David Warner recorded his twin centuries but the effort put in by Clarke can simply not be ignored. Australia batting first put on a huge total of 494 runs, Clarke top scoring with 161 runs. This effort is special because in these times Clarke had a lot to deal with, his back problems , injury problems and much more but he has such a strong character and self belief that he manages to score through a period of difficult even.
