Under these strong new measures, offenders can be prosecuted under a new offence and face a fine of up to $132,000 and/or seven years jail time if they deliberately light or allow a fire to escape their property on a Total Fire Ban day.

"There are new laws to ensure firebugs will have to face the consequences of their actions," Minister for Police and Emergency Services Stuart Ayres said.

A jury can still find someone guilty of the existing offence which carries serious penalties of up to $110,000 and up to five years jail time, if they think the person did not have enough warning that a Total Fire Ban was in place.

Other changes allow NSW Police and RFS to penalise less serious offenders with fines up to $2200 effectively covering off on penalties for would-be firebugs as we move into bushfire season.

"We are seeing a lot of people ignore warnings and conducting burns on their own properties with complete disregard for Total Fire Bans," Mr Ayres added.

"Out-of-control fires have a devastating impact on life, property and communities. It's only right that those who cause this devastation should have the book thrown at them."

Other amendments to the Rural Fires Act 1997 will streamline fire permit requirements and ensure those who throw lit cigarettes, matches or other "fire objects" from a vehicle will be held accountable, not just the registered owner.

"Those idiots who throw lit cigarettes or matches from cars during a Total Fire Ban can already be hit with double the penalty, but will now be unable to blame it on someone else," Mr Ayres said.

"These tough changes aim to not only deter, but put an end to such reckless behaviour."
