The Western Australian government will spend $125 million boosting its arsenal of firefighting vehicles and tankers.
Premier Mark McGowan says hundreds of vehicles and tankers will be built in the state to ensure firefighters have the most up-to-date equipment.
The announcement on Thursday comes two days after Coroner Sarah Linton delivered her findings into the deadly Esperance bushfires in 2015 and called for more resources to combat the growing threat of climate change.
Farmer Kym Curnow and backpackers Thomas Butcher, Anna Sushchova Winther and Julia Kohrs-Lichte died in Scaddan during lightning-sparked blazes that lasted 11 days in November 2015.
The coroner said in her findings it was clear that such large and complex fires were no longer an isolated event and this was due in part to climate change.
She has called on the Department of Fire and Emergency Services (DFES) to immediately expand its presence in the Esperance region from a single officer to three staff.
Mr McGowan has declined to commit to the additional staff, saying he will be guided by the DFES on their requirements.
He said the two new contracts, worth $75 million and $50 million, would ensure local firefighters had modern equipment to deal with blazes.
The premier said the government had been investing significantly in bushfire mitigation and giving greater autonomy to local firefighters.
"We've done as much burning off as we can possibly do," he said.
"We put a huge effort into mitigation ... and the last few years have seen far bigger burnoffs than the years prior to that. So we're doing all we can."
Much of the manufacturing work will be carried out in the coal mining town of Collie, where efforts are being made to diversify the local economy.
Tenders will also be called for a third contract worth about $47.5 million to provide up to 300 medium duty tankers.
