Firefighters are struggling to control the huge bushfire on Fraser Island, off the east coast of Queensland.
The bushfire was sparked by an illegal campfire in mid-October and has destroyed at least 82,500 hectares of the Unesco World Heritage site.
A heatwave in south-east Australia has exacerbated bushfire conditions.
The Fraser Island fires are among the most serious since the end of last summer. Australia's 2019-20 bushfire season was its most intense on record, though not its most deadly.
