Will Young smashed a masterful 130 to steer a second-string New Zealand side to a seven-wicket win over Australia in a World Cup practice match, outshining an unbeaten 89 from Steve Smith.
The visitors chased down their 278 target with 10 balls to spare, inflicting a first defeat on Australia in 10 games, although this was not considered as a full international.
Young, who is uncapped and not part of New Zealand's World Cup squad, eventually ran himself out after smacking 11 fours and two sixes in his 132-ball knock.
George Worker (56) and Tom Latham (69*) were also among the runs as New Zealand, missing their key players in Kane Williamson, Martin Guptill and Trent Boult, made 283 for three in reply to Australia's 277 for six.
Australian pace spearhead Mitchell Starc made his long-awaited return since tearing a muscle, and was the pick of a lacklustre bowling attack, taking 2-14 off five overs with trademark yorkers before being taken off from the action.
Earlier, former Aussie skipper Smith was the star attraction with his 89, including four big sixes, in only his second game in Australian colours since his one-year ban for ball-tampering last year.
He came to the crease when Shaun Marsh was out for 28 and looked in decent as Australia look to defend their title in England and Wales.
Usman Khawaja and Glenn Maxwell were also in form, scoring 56 and 52 respectively.
But David Warner, who made 39 on his return in the first of the three unofficial matches in Brisbane on Monday, did not fare so well.
Australia won the first match by one wicket, with the final game at Allan Border Field on Friday.
