David Warner and Travis Head both hit fifties as Australia raced to 118-0 off the first 10 overs in their World Cup clash against New Zealand on Saturday.
Warner, who turned 37 on Friday, smashed his 32nd ODI half-century off 28 balls with three fours and five sixes.
Head, playing his first match of the World Cup after breaking his hand in South Africa on the eve of the tournament, took just 25 balls to reach his 19th score of fifty or more in one-day internationals.
New Zealand had won the toss and opted to bowl first against five-time champions Australia in Dharamsala.
The Black Caps, runners-up at the last two World Cups, are well-placed to reach the semi-finals with four wins from five games.
They made one change from the side which suffered their only loss so far to India at the same Himalayan venue last week.
Jimmy Neesham replaced Mark Chapman, who has a calf injury, while Australia brought in Head for all-rounder Cameron Green.
Australia are currently fourth in the 10-team table with three wins and two losses.
