A containment line is being strengthened against a seven-week-old bushfire that's blackened almost half of world heritage-listed Fraser Island.
Several blazes are still burning but water bombers are helping ground crews control them, Queensland Fire and Emergency Services said on Saturday.
"Where ground crews cannot access the inaccessible terrain, waterbombing aircraft are working to reduce the intensity of the fire," a QFES update said.
Weather conditions are expected to worsen from Sunday through to Wednesday, causing smoke to affect visibility and air quality on the island and nearby mainland areas.
At 9.15am Saturday people in the Kingfisher Bay Resort area were advised to have a fire safe plan or be prepared to leave because the situation could escalate.
Residents and tourists were told fire fighters could not be expected to save every property or come knocking at their door.
Travel to the popular tourist destination remains restricted to local residents, essential service providers and emergency services.
Tourists already on the island have been advised to stay close to their accommodation and avoid road and tracks.
The bushfires were sparked by an illegal campfire which started on October 14 and has led to the destruction of at least 82,500 hectares of the national park.
The fire continues to burn on multiple fronts on the east and west sides of the island.
About 100 specialists firefighters are on the ground.
They are being supported by fixed-wing bombers, heli-attack bombers, air attack platforms, an air observation platform, the large aerial tanker and an LAT lead plane.
Fraser Island is about 250km north of Brisbane, 123km long and covers 181,851 hectares.
