South West residents have been urged to remain vigilant following a suspicious fire on December 29.
The bushfire near Tuart Forest National Park and Ludlow State Forest was reported at 2.25pm and was contained by responding brigades.
Department of Fire and Emergency Services issued an all clear and a reminder that open outdoor fires are not permitted.
Department of Fire and Emergency Services Lower South West region acting superintendent Danny Mosconi said investigations were ongoing into the arson.
“There have been a number of suspicious fires in the Capel and Ludlow area over a number of seasons now,” he said.
“The key message we have is if the community notices anything suspicious to contact Crime Stoppers.”
Mr Mosconi said deliberately lit fires during bushfire season were particularly worrying for the regions emergency volunteers.
“Any fire that is suspicious is a concern for us,” he said.
“There is the potential to affect lives and properties if it gets out of control.
“At this time of year, we want our volunteers to be home with their families, not being called out for occasions like this.”
The suspicious fire followed a fire off Caves Road on Wednesday, December 27.
The Yallingup Rural Volunteer Bush Fire Brigade reported on its website a quick response by the Wilyabrup brigade limited the damage to two paddocks.
The Wilyabrup light tanker responded and was followed by the two Yallingup brigade trucks and the Coastal brigade trucks.
The fire, which is thought to have started behind a holiday rental, quickly spread towards an adjacent house before it was brought under control.
According to the Wallcliffe Volunteer Fire Brigade Facebook page, Department of Parks and Wildlife attended a campfire left burning after a party at Kilcarnup.
