'Elevated bushfire danger': How each state and territory is preparing for spring weather

Fire authorities across Australia are preparing for a spring fire season that could bring sharply different risks depending on the region, with some areas facing an early bushfire threat while others contend with delayed wet seasons and severe weather.

The Bureau of Meteorology's Michael Egan said a strengthening El Niño is influencing the outlook, but it is not the only climate driver at play.

"I will just remind everyone that the bureau's long-range forecast does incorporate all of the influences from our surrounding oceans and the atmosphere as well as other long-term climate trends.

"I mention that because I'm sure most people are aware an El Niño event is underway, it is strengthening, and it is going to be a very strong one," Egan said.

Authorities say conditions vary significantly from region to region, with dry weather, warmer temperatures and increased fuel loads contributing to the risk.

Victoria is among the states preparing for an early start to the bushfire season, with hotter, drier conditions expected in spring.

Emergency Management Commissioner Tim Wiebusch said significant fire danger could emerge from October.

"Victoria can expect a hotter and drier spring, which means that we could see significant bushfire risk commencing from as early as October this year, and our emergency services in Victoria are now starting to prepare for that scenario that could mean that we could see campaign fires start as early as October and take us right through the summer months," Wiebusch said.

Parts of southern inland Queensland and the southeast are also expected to experience above-average fire danger.

Acting Deputy Chief Officer Aaron Howard said crews are already conducting hazard-reduction burns and other mitigation work in high-risk areas.

"At Queensland fire department we continue to prepare, our crews continue to take hazard reduction burns and mitigation activities in high-risk localities across the state where conditions allow," Howard said.

In the Northern Territory, authorities are preparing for the possibility of heightened fire danger across several regions at the same time.

Fire and Emergency Commissioner Andrew Warton said a delayed Top End wet season could extend the period of elevated risk in the north, while other parts of the territory enter their own high-risk periods.
