A woman and two men have suffered smoke inhalation after a caravan fire at Calliope.
Police, paramedics and three fire crews were called to the scene off the Bruce Highway and Sawmill Road at around 3.40pm yesterday.
The woman in his 50s and two men in their 60s were transported to Gladstone Hospital in stable conditions.
Queensland Fire and Emergency Services say smoke was coming from an item on fire inside the caravan and they had the blaze under control by 4.15pm.
Fire investigators will be attending the scene today.
