Northern Territory authorities are warning people to be on the lookout for arsonists, as hot windy conditions fan bushfires in central Australia.
Bushfires NT senior fire control officer Geoff Kenna said there were several fires currently burning in Central Australia, although none threatened lives or property.
Mr Kenna said the current fires were thought to have started from lightning strikes, but people should be alert to firebugs.
"If you see anyone around the place who may be acting suspiciously out in grasslands etcetera please report it to police," Mr Kenna said on Monday.
"We do have issues at times with arsonists and we encourage people to keep an eye out for those people," he told AAP.
"We just can't afford to have fires starting in the weather conditions we are experiencing now and that are forecast in the next week or two."
Among the current fires that were under watch was one at Mt Skinner, 180kms north of Alice Springs, another at Pine Hill 160km north-northwest of Alice Springs, and four at Undoolya Station, east of Alice Springs.
Mr Kenna said in Central Australia the humidity was very low, with consistently hot weather in recent days.
The Bureau of Meteorology has forecast a top temperature of 43C for Alice Springs each day until Thursday.
"Closer to the rock they have been getting temperatures of around 45C fairly regularly," Mr Kenna said
"We have been getting very strong, gusty winds that have built through the day and been very severe in the afternoons."
He said introduced buffel grass, brought into the NT as a dust suppressant and cattle food, was now widespread and was a fire hazard because it grew quickly and burned at hot temperatures.
