The minimum time behind bars for convicted arsonists is set to almost double from five years to nine years.
The NSW state government announced the crackdown following a recommendation of the Sentencing Council to help ensure those who commit bushfire offences spend more time behind bars.
Member for the Dubbo electorate Dugald Saunders said with another hot and dry summer around the corner, it is essential there are strong laws in place to protect farmers and communities who are already battling drought.
"My message to would-be firebugs is to stop and think about the children and families who could be killed or injured and the huge economic and emotional toll of being homeless and having to rebuild homes and farms from scratch," he said.
"Bushfires don't just impact on one person, they also hurt the infrastructure of a community and they take a massive amount of resources to fight.Fire and Rescue NSW Dubbo station commander Chris Cusack
Fire and Rescue NSW Dubbo station commander Chris Cusack said bushfires have the capacity or affecting a large number of people and communities.
"Bushfires don't just impact on one person, they also hurt the infrastructure of a community," Mr Cusack said.
"They take a coordinated response from Fire and Rescue and the Rural Fire Service, and they take a massive amount of resources to fight.
"A normal house fire, whilst it is devastating for the people involved we normally can contain them to the area of the house, but bushfires are hard to access, we fight with limited water, and they are incredibly dangerous."
NSW Rural Fire Service Acting Commissioner Rob Rogers welcomed the latest reforms and called on the community to report suspicious behaviour.
"NSW firefighters already have a difficult and dangerous job responding to emergencies and keeping the community safe, let alone having to put their lives on the line because some reckless person deliberately started a fire," he said.
"The prolonged drought means there is an increased risk of fires. It is important people remain vigilant and report any suspicious behaviour, so offenders are caught."
In 2018, Attorney General Mark Speakman asked the Sentencing Council to review the standard non-parole period.
As part of its review, the Sentencing Council received submissions from stakeholders including the Law Society of NSW, Legal Aid NSW, NSW Police Force, the Office of the Director of Public Prosecutions and the Rural Fire Service Association.
The majority of stakeholders agreed the bushfire offence's standard non-parole period should be increased.
The offence applies to the charge of intentionally causing a fire and being reckless about it spreading on public land or someone else's property.
Police and Emergency Services Minister David Elliott said one act of stupidity could bring a community to its knees.
