Marnus Labuschagne scored a century as Australia started strongly against New Zealand on the first day of the third and final Test in Sydney.
Labuschagne hit 130 - his fourth century in five Tests - as Australia reached 283-3 at stumps at the SCG.
He and Steve Smith, who made 63, shared a 156-run partnership as New Zealand toiled in the field.
Both teams wore black armbands in tribute to those affected by widespread bushfires in Australia.
New Zealand have a depleted side with captain Kane Williamson, fellow batsmen Henry Nicholls and left-arm spinner Mitchell Santner all missing with illness, while pace bowler Trent Boult has returned home with a fractured hand.
There was a minute's applause before the Test began to honour Australia's firefighters.
