Australia proved that they are strong by winning series against South Africa but the most exciting part was surprise performance from Dewald Brevis whose century in second game put Australia under pressure. And Tim David hitting was bright spot and it was Mitch Marsh good performance and he stepped up to help Australia regain control and win series. So Australia is very strong team new players can always make game more exciting.
The Australian team is ranked second in the T20 rankings ini the ICC, while the South African team is ranked fifth, so it is natural that the Australian team will be ahead of the South African team in terms of strength.
However, even though the Australian team was strong in this series and won the series, they had an average performance against the South African team because during the match, it often felt like the Australian team was under a lot of pressure. Moreover, every match ended in a close fight. And after the second match, it became quite unpredictable who would win the series.
If we analyze the results of South Africa's last ten T20 matches, it can definitely be said that South Africa has performed very poorly. If we consider the final ten statistics, South Africa has lost seven matches, won one matche and drawn two matches. South Africa won the second match of this series, their only win out of ten T20 matches. So South Africa's overall performance is not good at all, meaning they competed but lost despite not playing very well.
