Dozens of firefighters have worked tirelessly overnight to contain a fire within Mount Gambier's landmark Crater Lakes district.
The blaze ripped through 50 hectares of land in the area, but no injuries or damage to property has been reported.
The Metropolitan Fire Service said the fire had been contained and firefighters were now working to put out the last of the flames.
"It's within containment lines now, so the crews will just still be working today to put out any hotspots," an MFS spokesperson said.
"There's no threat to lives or property at this stage."
About 150 firefighters will continue backburning operations along the northern and southern ends of the fire, with air bombers supporting ground crews throughout the day.
Close call
Fire crews were yesterday able to stop the blaze from entering the conservation park in the Valley Lake area.
Resident Maureen Klintberg, who lives at the foothills of the Crater Lakes, said the situation was "rather threatening" when the fire came within 500 metres of her home.
"There are five houses who back immediately on to the pines, and they were feeling more threatened than what we actually were."
Ms Klintberg said residents activated their fire plans, but thankfully did not need to evacuate.
"We had our sprinklers on and we're vigilant with what was happening," she said.
"Residents of [the street] have been aware of the possibility of a burn, over a number of years, because of the build-up of undergrowth under those pine trees.
Ms Klintberg said thick smoke was visible near her home and she was woken several times throughout the night as pine trees fell.
The MFS has appealed to members of the public to keep away from the area and to avoid flying drones.
The plea comes after reports of spectators entering the area.
