Trent Boult gave them a solid start by dismissing in-form Aaron Finch cheaply. Reminiscent of Michael Bevan, he smacked 11 fours as part of 71 from 72 balls, with his contribution especially vital considering he was Australia's last recognised batsman.
Allrounders: Glenn Maxwell and Jimmy Neesham are the best all-rounders.
Khawaja - dropped by Guptill second ball and offering several chances later in his innings - took his time, compiling his innings largely in singles, while Carey played an aggressive knock.
Starc's 19 wickets from seven matches, more than any bowler in the tournament, have been instrumental in Australia booking a place in the last four with two group matches to spare.
A feat the Black Caps batsmen couldn't do justice.
In response, Australia found the breakthrough in the 10th over as Henry Nicholls, into the side for Colin Munro, gloved to Finch for just eight off the bowling of Behrendorff. Kane Williamson (40) and Taylor then combined to steady the innings before Starc induced an edge off Williamson's bat.
Starc was the pick of the bowlers, taking 5 for 26. Ferguson bowled a short delivery and Smith duly pulled.
The eventually hefty margin of defeat makes the Black Caps slightly more vulnerable on net run rate - though Pakistan and Bangladesh will still need a significant turnaround to challenge them - but of more concern will be the batting performance.
"It's another big game for us, obviously we have cemented out spot in the semis - now we want to try and finish as high as we can and play some really good cricket headed towards the finals series", Starc said.
