Cummins led Australia to a six-wicket victory on the third day of the fifth Test in Sydney, with the home side having bounced back following a 295-run defeat in the series opener in Perth.
They responded with a 10-wicket win in Adelaide, and after the third Test in Brisbane ended in a rain-affected draw, a dramatic win on the fifth day of the fourth Test in Melbourne put Australia 2-1 up.
“It has been an amazing series,” said Cummins, 31. “It has been in the calendar for a while and is one you’ve had your eye on it for a year or two. It has lived up to all the hype.”
Victory in Sydney, helped by fast bowler Scott Boland’s 10-wicket haul, also ensured Australia will contest the World Test Championship final against South Africa at Lord’s in June.
“The extra layer is now securing a spot in the World Test Championship final, which was always a huge goal for us in this cycle and we’ve done it,” Cummins said. “So we are really satisfied.”
