PM assures fire-ravaged Qld of support

Prime Minister Scott Morrison has assured fire-ravaged Queensland communities they'll get the support to fight the bushfires and recover from the devastation.

At least 15 homes have been lost to fires that ravaged southern Queensland amid wind gusts of up to 90km/h.

Since Thursday, bushfires have destroyed 11 homes in the Sarabah area, inland from the Gold Coast, and a home near Mareeba in north Queensland.

Three homes and four other structures were lost in the border towns of Applethorpe and Stanthorpe overnight, where fires forced hundreds of evacuations.

Mr Morrison assured the communities on Saturday they would get all the support they needed to deal with the fires, and in the recovery that takes place afterwards.

"Particularly there at Binna Burra and Stanthorpe, I think there are going to be some challenges there and we'll be there to work with the state government to get it done," he told ABC Southern Queensland.

There were 69 fires burning across the state on Saturday.
