A disaster crew will be sent to New Zealand to help assist in the response and recovery from former tropical cyclone Gabrielle as the death toll rises to nine.
A 25-strong team of expert officers from Australia will assist on New Zealand's north island, which has been hit by heavy flooding.
The storm cut off towns, washed away bridges and left thousands of people homeless or displaced.
A second volunteer firefighter who was caught in a landslide near Auckland died in hospital on Thursday night.
The impact assessment team from Queensland Fire and Emergency Services will be deployed to regional areas within the next 24 hours to support NZ crews.
Foreign Minister Penny Wong said Australia stood ready to help should more assistance be needed.
"Our close relationship with New Zealand has meant we have been able to mobilise assistance quickly in response to this disaster," Senator Wong said.
Emergency Management Minister Murray Watt said Australian teams had become experts in responding to floods in recent years, and the disaster crew would be of great help.
"In the wake of our Black Summer bushfires, the New Zealand government moved quickly to provide assistance here on the ground. Their crews also supported our State Emergency Services during the recent floods," Senator Watt said.
"Our neighbours have been there for us, and we are more than willing to return the favour in their hour of need."
More than 70 emergency responders were also recently dispatched to Türkiye to help respond to devastating earthquakes in that region.
