UPDATE 8.20AM: EMERGENCY services are investigating the cause of a scrub fire along Walkers Rd in Urangan, which started yesterday afternoon.
Three fire crews and police were called to the scene about 2pm on Wednesday, and were able to control the flames within an hour.
The fire spread across a 200 by 80 metre patch of scrub behind the gymnastics club, however firefighters said no buildings or homes were at risk.
Torquay Fire Station Officer John Pappas said there were a number of factors that lead firefighters and police to believe the blaze was suspicious.
"There was nothing natural about it," Station Officer Pappas said.
"There is no reason why this fire would start by itself."
The Station Officer said if it had been a typical dry, Spring day, the situation could have been more difficult to contain.
"It could have been a lot worse," he said.
"Fortunately today's weather condition was favourable, but with any fire, the potential for it to be dangerous is always there."
He said the incident was a timely reminder for people living in more urban parts of the Fraser Coast to make sure they had a bush fire plan in place.
"It's that time of year, everyone needs to be prepared," he said.
