A Eurobodalla Shire Council spokesperson said the council became aware of the event following complaints from nearby residents.

"The property owner has been formally warned by the council that failure to comply with the Order is an offence, and legal action will be pursued if the event takes place," they said.

"NSW Police have also been informed."

The spokesperson said people planning to attend the event would have been required to drive on the Knowles Creek landslip detour, which has a five-tonne load limit in place and is restricted to only residents.

"Extra traffic and the expected rain this weekend creates potential for further damage to the road and more inconvenience for residents of the area," they said.

"The council is urging people not to attend the event - not only to preserve the road but out of respect of the area enduring a difficult recovery from the Black Summer bushfires."

The council said the property owner had run similar events in the past without consent, and had been issued with penalty infringement notices.
