Conway stars for New Zealand with 92 off 58
Neesham adds late impetus with 26 off 13
Allen's 42 off 16 gets New Zealand off to flying start
England face Afghanistan in day's later game from 12:00 BST
That's all for this Super 12s opener.
England have just won the toss in Perth and asked Afghanistan to bat first. We'll have reaction from Sydney in coverage of that game.
You can read the match report of Australia's heavy loss to New Zealand right here.
Now it's all eyes on England. Bye for now.
They then backed that up with some stunning catch and dead-eye bowling.
The Aussie were skittled for just 111.
But what a night for New Zealand in Perth.
They have started their bid to win the T20 World Cup for the first time with a massive win over the Aussies.
They were set on their way by racking up 200...
I wonder what England will make of that? Across Australia, in Perth, they are about to start their campaign against Afghanistan.

What a performance. They have thrashed Australia. That is a mighty effort.

There is some soul searching to do for the Australians. The tournament isn't over but they are going to have to improve their performances. Their next match is an absolute crucial match.
Cummins c Conway b Southee 21 (Aus 111 all out)
And that is that.
New Zealand have hammered hosts and defending champions Australia in the opening game of the World Cup.
An 89-run margin is an absolute mauling.
Pat Cummins skies Tim Southee into the gloves of Devon Conway to complete the rout.
A Kiwi win is no surprise, but who saw this thrashing coming?
Target 201
This is on course to be Australia's biggest T20 loss in terms of runs to New Zealand and against allcomers in a World Cup match. Quite the shallacking.

Trent Boult was too smart. The old knuckle ball. He's bringing out all the party tricks.
Zampa b Boult 0 (Aus 109-9)
Two in two!
A swipe from Adam Zampa sees his furniture rearranged. Trent Boult on a hat-trick to finish the match....
Starc b Boult 4 (Aus 109-8)
Trent Boult wins the battle of the left-armers. Mitchell Starc swings at Boult and has his stumps splattered.

Phillips has been very good in the field. We saw a big superman dive earlier. I'm very impressed with him.
Target 201
Just for the record, Ferguson is bowling at about 90mph. Imagine how quick he would be without a moustache to slow him down.

'I don't care how quick your bowling is Lockie, I'm going to dispatch you.'
Target 201
Pat Cummins is still giving it some humpty. Ferguson has been whalloped over mid-wicket for a maximum.

Target 201
Australia won't have long to pick themselves up from this. They have to make the long trip to Perth to play Sri Lanka on Tuesday. All of a sudden, that is a must-win.
Target 201
This match is continuing, but the contest is done. It's just how these two teams can alter their net run-rate. England's game against Afghanistan is less than an hour away.

The Australians have been outplayed in bat and ball by New Zealand in their opening game.
Target 201
Mitchell Starc is the new man. Earlier this week I saw Aussie coach Andrew McDonald touting him as a reserve wicketkeeper, probably because he could get some tips from wife Alyssa Healy.
