“Conditions are now very dangerous and firefighters may soon be unable to prevent the fire advancing,” Queensland Fire and Emergency Services said.
“The fire may pose a threat to all lives directly in its path.” Tony Wellington, the mayor of Noosa, told Reuters many of the residents in the affected north, accessible only by ferry or via the beach, had got out this week.
Across the country, in Western Australia, officials were responding to two emergency bushfires that had destroyed two homes and damaged another.
The fires have sparked increasingly acrimonious debate over climate and fire-prevention policies, with the ruling conservative Liberal Party and the minor opposition Australian Greens exchanging barbs.
Former deputy prime minister Barnaby Joyce was among those who have suggested that climate activists were at least partly responsible for the fires by lobbying to reduce so-called back burns, fires deliberately lit to clear dry undergrowth.
Independent lawmaker Zali Steggall said it was very “unbecoming of our parliament” for Mr Joyce to make such remarks.
