A backyard shed and a truck have gone up in flames in separate fires.
The first blaze started in a large garden shed at a home on Casilda Street in Falcon around 12.30pm on Sunday.
Firefighters managed to contain and extinguish the blaze within an hour, preventing it from spreading to neighbouring properties.
No one was injured but the shed was completely destroyed.
Then around 1.50am on Monday, the Department of Fire and Emergency Services received a triple-zero call about a truck fire on Boundary Road in Dudley Park.
The truck, believed to be carrying tyres, burnt for hours and was extinguished by 4.30am.
Firefighters were then called back to the scene at around 7.15am after the fire reignited.
It took them another half an hour to put it out.
The causes of both fires are not yet known.
