Four houses and a hairdressing salon have been damaged in separate fire incidents across central and southeast Queensland.

Firefighters have been busy battling four housefires across central and southeast Queensland.

A two storey timber home in Toowoomba, on the Darling Downs, went up in flames just before 2am on Saturday, however it was not considered to be suspicious.

Crews were then called to a blaze at a home in Mount Morgan, in central Queensland, after 2:30am.

The house was unoccupied at the time.

Later in the morning, smoke began billowing from the garage of a unit in Northlakes, north of Brisbane.

Three pumps were used to battle the flames, which appeared to have spread from the garage.

A 36-year-old man was taken to the Redcliffe Hospital to be treated for minor burns to one of his hands.

The most recent incident saw a home in Gloucester Street, South Brisbane, catch fire around 12:30pm.

Queensland Ambulance crews were kept on stand-by outside as firefighters brought the flames under control.

All occupants were accounted for.

The owners had been in the home for 60 years, according to media reports.

A business on North Stradbroke Island has also been gutted by an overnight fire.

The Straddie Styles Hair Salon caught alight just after midnight.

Fire investigators spent Saturday morning at the scene, which was sealed off with police tape.

The incident was believed to be suspicious.

The salon’s owner and manager took to Facebook, vowing to rebuild.

“We are just devastated,” the post read.

An accompanying photograph showing the blackened shell of the building prompted expressions of sympathy from dozens of residents.
