The NSW Rural Fire Service (NSW RFS) portal means residents can use their mobile phone or desktop computer to lodge their notifications about planned hazard reductions or burn-offs 24 hours a day, seven days a week.

NSW RFS operational officer Gary Hansen said by using the new tool at www.rfs.nsw.gov.au/notify, users can help prevent unnecessary emergency calls.

"As we approach the bushfire season, many landholders are taking the opportunity to burn-off - but it's important they do it safely and let us and their neighbours know," he said.

"Landholders need to make sure they've obtained any required permits and permissions, as well as notifying neighbours and fire authorities 24 hours before lighting up.

"This tool makes it easier to notify the NSW RFS before conducting your burn. If fire services know about it, it can help prevent unnecessary emergency calls and firefighters from being responded."

By using the new tool, landholders will be notified of any Total Fire Bans and will be advised to not proceed with their burn.

Mr Hansen said while landholders are encouraged to reduce fuel loads on their property, it is imperative that it is done safely and legally.

"Before lighting any fire, you need to have adequately prepared fire breaks and have firefighting equipment on hand to ensure the fire does not escape," he said.

"Every landholder has a responsibility to prevent fire spreading from their property and there can be serious consequences for people who light fires and leave them unattended."

Oberon fire crews responded to 44 grass, scrub and bushfires in the last fire season.

The first fire in the Oberon area was a two-hectare blaze on Shooters Hill Road in late September, and the last was a small grass fire on Mutton Falls Road at O'Connell in late March.

The new online burn notification tool is available at www.rfs.nsw.gov.au/notify.

Landholders can still notify the NSW RFS by contacting their local Fire Control Centre.
