The Queensland Fire and Rescue Service says it urgently needs volunteers to help combat thousands of bushfires this year.

Rural and urban crews have battled more than 650 fires this week sparked by arsonists, lightning strikes, lawnmowers and barbecues.

Yesterday there were more than 60 blazes burning across the state and 40 were still going late last night.

Assistant Fire Commissioner Neil Gallant says the fire service needs help to deal with the threat.

"We are always keen to get people involved in the Rural Fire Service even if you don't want to be on the frontline fighting a fire," he said.

"There are other classifications of brigade members that help in the support role, like I said, you don't have to be on the front line fighting fire in mid-40 degree heat.

"So we are really keen for people living in the area to contact their local fire brigade."

Mr Gallant says crews are keeping an eye on fires on Bribie Island north of Brisbane and near Murgon in the south-east.

"Since Sunday we have had 660 vegetation fires across Queensland, no homes lost, and a number of them are still uncontrolled but not causing great concern," he said.

"There have been some fires that are suspicious we have got people in to investigate those.

"Most of the fires have been lightning strike fires in western Queensland not much we can do about those unfortunately."
