Ponting, hired as an assistant coach to Justin Langer for Australia's World Cup campaign, watched Aaron Finch's side fall to South Africa and England in successive matches to bow out of the tournament after they had been the first side to book their place in the semi-finals.
Injuries did not help Australia's cause and Ponting was not prepared to wear the blame for the side's tactical preparations.
"Tactically, I think we got things right. Personnel-wise, we picked the best team that we could for every game," Ponting told Cricket Australia's website (cricket.com.au).
"Unusually for Australian teams in World Cups, we played our worst cricket in the most critical moments.
"That'll be the thing that gets spoken about the most and see if there's any reason behind it."
