Wanneroo’s chief bush fire control officer Phil Hay said they attended three fires in Carabooda earlier this week which started after people used ride-on mowers to slash grass.
‘We were able to get on them very quickly ” we were lucky that we had crews close by,’ he said.
Mr Hay said anyone using mowers or other equipment in grassy or bush areas should keep watch of the area afterwards in case fires sparked.
‘Be very careful ” we have got bad weather coming in the next few days,’ he said.
The Department of Parks and Wildlife managed several fires around Yanchep National Park and the Gnangara pine plantation in the past week.
Several DPAW firefighters and almost two dozen Department of Fire and Emergency Services crews attended the Gnangara fire, supported by two fixed-wing water bombers and four helitacs.
It started last Friday afternoon and burnt through 40ha before they issued the all-clear the following afternoon.
At the same time, about 40 firefighters from DPAW, DFES and council crews were fighting a fire sparked by lightning south-east of Yanchep National Park.
The fixed-wing water bombers and two helitacs assisted ground crews, and that fire burnt through 130ha over two days.
Yesterday, DPAW issued advice about another bush fire at the entrance to Yanchep National Park, which several crews and two water bombers attended.
The fire burnt through about 2ha and Yanchep Police Sergeant Jason Macander said they were treating it as suspicious, urging anyone who saw suspicious behaviour in bush areas to call 000 immediately.
