Queensland Premier Annastacia Palaszczuk has pleaded with tourists not to abandon regions decimated by bushfires.
She said the government would launch a campaign to lure visitors back to areas like the Gold Coast hinterland as soon as the fire danger had passed.
"Once the fires have gone away - we've still got a couple of weekends to go - but we need to run a great tourism campaign to say to everyone come back and support the region," she told Seven's Sunrise program on Monday.
The Sarabah fire destroyed 11 homes and significantly damaged the historic Binna Burra mountain lodge.
Around 70 lodge employees are out of work while the owners start to rebuild.

The state's top cop has confirmed that fire is now being treated as suspicious and that a complex investigation is underway.
"We do have concerns about the start of this fire," Police Commissioner Katarina Carroll told reporters during a tour of destroyed properties in Beechmont on Sunday.
"We will be relentless in pursuing whoever it is that lit the fire, not only here, but across the state."
The fire remains of the most concern to authorities because it is burning in valleys within the Scenic Rim that are hard to access.

Authorities have spent the last few days strengthening containment lines around blazes across the state while weather conditions have eased.
The fire danger remains high to very high ahead of deteriorating firefighting conditions forecast on Tuesday.
More than 40 fires are still burning across the state, with officials warning some could burn for months because the ground is bone-dry and there is no significant rain in sight.
The state government has pledged $200,000 to help bushfire victims.
Bushfire threat set to return across NSW
The return of warm westerly winds and higher temperatures across NSW is also set to push bushfire risk back to dangerous levels.
Fire conditions across NSW eased on Sunday, with firefighters gaining the upper hand on two blazes while another remains out of control in the state's north.
The Rural Fire Service has downgraded the alert level to advice for a fire burning in the New England region about 15 kilometres east of Glen Innes.

The out-of-control blaze has burnt more than 9000 hectares but the RFS said the threat to homes has eased and roads are reopening.
But Monday's weather - with a strong wind warning forecast for Sydney, the Hunter, Illawarra, Batemans and Eden Coast, and temperatures pushing 30C - would cause fresh headaches for firefighters.
Favourable conditions for firefighting wouldn't return until Wednesday.
"Fortunately today we didn't have as bad a day as yesterday. Most firefighters held on their current containments," an RFS spokesman told AAP on Sunday.
"[Tomorrow], it will be a problem day."
About 12 fires were on Sunday burning out of control across NSW.
In northern NSW's Drake, firefighters were getting control of a blaze which has burnt more than 53,000 hectares but been downgraded to advice alert level.
Fire crews had also gained the upper hand on a bushfire burning in Bees Nest near Armidale which is at advice alert level.
The blaze has razed more than 90,000 hectares and continues to burn on multiple fronts within Guy Fawkes River National Park, Mount Hyland Nature Reserve and Nymboi-Binderay National Park.
