I might be wrong but Imo and observation Strac lost all his mojo after Sand_paper_gate_saga. I noticed him struggling numerous time after his South Africa's stint. He might still able to give match winning spell once a while which everyone witnessed in last T-20 match against Windies but its clear that he's not same the Starc.
It may or may not be due to the sand paper scandal. But for the last many years, his form has remained poor. As you mentioned, once in a blue moon he performs like a world class bowler. But on majority of the occasions, he is quite ordinary. But the problem for Australia is that he's still their best bowler. This is not the Australian team we had one or two decades ago. Perhaps Mitchell Johnson was their last world class bowler. After he retired in 2018, Australian bowling has struggled, especially in pace department. Also, Starc used to perform well when he bowled in tandem with Mitchell Johnson.

Yeah, 2 back to back Border-Gavaskar Trophies failure, dropped from the ashes in 1 match, i guess. Kinda declining after his stellar performance in the World cup, although he did excellent job against Kiwis in 2020 home series but again New Zealand is their Srilanka.
I think Cummins would come back soon and then it should be okay overall.
Windies is fav finalist for next T-20 WC
England-NZ seems fav for the next WC
Pakistan is potential candidate for the next WTC finalist, if they get their shit together. Their fixture seems easy in this cycle.
