Auckland opener Glenn Phillips smashed an 84-ball century but it wasn't enough for New Zealand's under 19 cricket team to maintain their unbeaten run at their tri-nations tournament in Dubai last night.
Having beaten Australia and Pakistan in their first two games, New Zealand came unstuck second time around against the Aussies, losing by five wickets.
New Zealand made 281 for nine, of which Phillips made 105, with six sixes. He shared a 148-run stand for the first wicket with Canterbury's Dan Stanley, who made 56.
The only other notable contribution was 30 from Central Districts' Josh Clarkson.
Australia got to 284 for five in 48 overs, on the back of 103 from captain Sam Harper, off 84 balls, sharing a 183-run third wicket stand with Patrick Page, who made 99.
Otago bowler Nathan Smith took four for 51.
New Zealand's last game at the tournament is against Pakistan tonight.
New Zealand and Pakistan are preparing for the world under 19 tournament in Bangladesh. Australia have pulled out of the cup on security grounds.
New Zealand 281-9 (G. Phillips 105, D. Stanley 56, J. Clarkson 30; A. Nair 4-29, T. O'Donnell 4-63) lost to Australia 284-5 (S. Harper 103, P. Page 99; N. Smith 4-51) by five wickets.
