Fire authorities have re-iterated a safety call surrounding bonfires after an incident reportedly caused an explosion at Park Ridge on Friday night.
Two crews were called to acreage property on Park Ridge Road after reports of a loud bang and a fire breaking out.
Nearby residents took to social media to report an explosion and shockwave which shook their properties, with posts from people as far away as Crestmead.
A Queensland Fire and Emergency Services spokeswoman said the fire had been contained by the time crews arrived, and firefighters spoke to the property owner about the size of the bonfire.
She reminded people that fires had to be two square metres or less.
"Anything bigger, you need a permit," the spokeswoman said.
She also warned people to keep water nearby and make sure flammable liquids were nowhere near the fire.
It comes after an arson attack on a property earlier this month, when molotov cocktails were hurled at a Logan Reserve house.
Four people were seen on CCTV hurling molotov cocktails over the fence of the house on Killara Boulevard, before running from the scene as the flames took hold at 2.13am.
Another shot shows a car outside the address being set alight, before the occupant runs outside.
