The council has issued close to 150 letters to Goulburn Mulwaree landowners urging them to clear long grass from their properties.
The move comes six weeks into the bushfire season's official start. Monday's hot and windy weather also sparked a total fire ban.
Mayor Bob Kirk urged people to prepare vacant land for the summer heat and bushfire season by slashing or mowing long grass now while it is green.
"We are asking our residents and owners of residential blocks to get on top of this issue now before the grass begins to brown off in the coming weeks," he said.
"It has been great to have so much rain over the past few months but this has caused a lot of growth and we need to prepare accordingly prior to summer. We cannot be complacent, as in just a few weeks the heat will be here and it may be too late to mow or slash some of these areas due to bushfire risk."
Goulburn has received 752.6mm of rain this year, according to Weatherzone. It is well above the 577.9mm average for the year to November. The Bureau of Meteorology recorded 93.8mm at Goulburn Tafe in October but other areas received more.
A council spokesman said the organisation had issued 148 letters in regard to overgrown property over the past month and would be sending further notices to owners of vacant land over coming weeks "strongly encouraging them" to prepare their land for summer.
"If these notices are ignored a draft order will be issued, which may then result in an infringement notice and penalty of $330 for residents and landowners who choose to ignore this," he said.
Long grass is particularly evident on blocks around Goulburn awaiting development, such as the former Saint John's Orphanage in Mundy Street. The former Supertex site in Chantry Street, where buildings were demolished after a developer bought the site in 2004, has also been overgrown for some time.
A council spokesman said the vacant blocks in residential areas were a particular source of concern not only due to fire risk but the dangers they presented in terms of vermin, snakes and weeds.
The Bushfire Danger Period in NSW commenced on October 1.
RFS Southern Tablelands district officer Cherie Roche said there had been few fires to date. Crews however did attend an outbreak in the council tip on Wilson Drive, Marulan on Monday afternoon. It was quickly contained.
Separate to this, she reinforced the council message for landowners to clear long grass while it was still green.
"It is much better to act now when there is less chance of it igniting," she said.
As for the fire season ahead, Ms Roche said it very much depended on how growth was handled amid reports of more rainfall in the months ahead.
The Southern Tablelands zone has experienced increased membership since the last fire season.
