Animal activists fear entire animal populations will be wiped out on Fraser Island as a massive fire continues to ravage large areas of bushland.
The blaze has been burning for more than a month, damaging more than 30,000 kilometres of pristine habitat.
Cheryl Bryant, of Save Fraser Island Dingoes, says it will take a long time for ecosystems to recover.
"We're going to lose so much of the smaller mammals on the island; the insects and reptiles are all basically co-dependant on each other,'' Ms Bryant says.
"The long-term effect, I guess that remains to be seen''.
The damage on native flora and fauna is compounded by the devastation caused by the 2019 summer bushfires, when flames tore through 13,500 hectares across 26 days.
Ms Bryant is seriously concerned the island will never be the same.
"Climate change is also impacting the island.
"These fires are more than likely getting larger and also hotter, so we really do need to intervene otherwise it's going to affect the whole ecosystem," she says.
Campers to blame
Campers who started an illegal cooking fire and failed to put it out are being blamed for the latest bushfire.
Ms Bryant says she it underscores the importance of following fire rules because when people don't it can cause widespread devastation to the environment.
"It's disgusting and it's irresponsible, and this is why we try to tell people, 'please obey the rules'.
"Don't approach any of the wildlife, don't have illegal campfires, and now this is the consequence of somebody doing the wrong thing," Ms Bryant says.
Backburning to take place
Better weather conditions on Friday are making it easier for water bombing planes to access the fire and for ground crews to start backburning on Moon Point Road.
Queensland Parks and Wildlife Director Mick Cubis says backburning should result in strong containment lines for when the wind swings back from the north early next week.
