Sydney - Trent Boult claimed career-best figures of five for 27 as New Zealand dismissed Australia for a modest 151 in the World Cup on Saturday as the four-time champions suffered a dramatic collapse.
From 80 for one, Australia lost eight wickets for 26 runs before Brad Haddin (43) and Pat Cummins (seven not out) put on 45 for the last wicket to provide a little gloss on the score as the majority of the 40,000 capacity Eden Park crowd in Auckland sensed victory and a spot in the quarter-finals.
Left-arm seamer Boult's five wickets came in the space of 18 balls for just one run as New Zealand condemned Australia to their second lowest World Cup total.
Tim Southee took two for 65 while left-arm spinner Daniel Vettori finished with two for 41 as New Zealand's bowling maintained the same momentum which helped them dismiss England for 123 in Wellington.
There was no hint of the drama to come as Australia reached 30 by the third over with David Warner, who made 34, and Aaron Finch (14) getting off to a flying start after the visitors opted to bat against their fellow tournament co-hosts.
But once Warner and Shane Watson (23) fell off successive deliveries the innings imploded.
Watson holed out off Vettori while Southee, who took seven wickets in the win over England, removed Warner leg before.
Vettori had Steven Smith caught behind for four before Boult took over.
The 25-year-old, who had figures of 5-0-24-0 in his first spell, bowled Glenn Maxwell (one) and then repeated the killer ball to send back Mitchell Marsh for a second-ball duck.
Australia captain Michael Clarke, playing his first international since December, drove straight into the hands of short cover in Boult's next over having made just 12.
Boult then bowled Mitchell Johnson and Mitchell Starc to better his previous one-day international best of four for 44 against Sri Lanka at Dunedin last month.
Australia, who beat England in their opener two weeks ago before seeing the clash with Bangladesh rained off in Brisbane, went into Saturday's game in good heart having won 11 out of their 16 one-dayers at Eden Park, including four of the last five.
"After the start that Australia got, to fight back was amazing," said Vettori.
"The noise when Trent got a couple of wickets got everyone involved. I don't think I've heard anything so loud since I've been in New Zealand."
At the WACA in Perth later Saturday, 5 500km away, two worlds will collide when mighty India tackle the United Arab Emirates' team of shipping clerks and airline staff, with at least two of the Gulf amateurs relishing the showdown.
All-rounder Krishna Chandran and wicket-keeper Swapnil Patil were both born in India.
But frustrated by the pedestrian pace of their playing careers in the country's over-crowded talent market, they decamped to the UAE to pursue jobs and cricket.
Chandran hails from Kerala and once featured for a Bangalore college club alongside Stuart Binny, a member of India's squad at the World Cup.
"It's going to be a big moment for people back home," 30-year-old Chandran, who moved to the Gulf in 2010, told wisdenindia.com.
"For people who saw me playing in my shorts, with a tennis ball, on the streets of my home village of Kollengode, it's going to be a big thing to watch me on TV, playing against India, in a World Cup match, at a ground like the WACA."
Patil is another Indian expat and is looking forward to meeting up with star batsman Ajinkya Rahane after the pair played in a variety of youth teams in Mumbai before the keeper moved to Dubai.
India have been in rampant form so far, beating Pakistan by 76 runs and then trouncing South Africa by 130 runs in games where they racked up two 300-plus totals.
The UAE have lost both their games, to Zimbabwe and Ireland, but only by four and two wickets.
India's in-form seamer Mohammad Shami, who took four for 35 against Pakistan and two for 30 against South Africa, will miss the game with a knee injury.
