Australian authorities issued new warnings and evacuation notices across the country's heavily populated southeast on Thursday as a return of hot weather fanned huge bushfires threatening several towns and communities.

A disaster notice in Victoria state, already in place for the past week, was extended by two days and people in danger zones were told to leave. In neighboring New South Wales state, authorities told residents to prepare for worsening weather conditions on Friday.

"These fires are absolutely still moving, still growing in our landscape and they pose significant risk to communities," Victoria Emergency Services Minister Lisa Neville said in a televised briefing.

Twenty-six people have died, thousands have been made homeless and thousands of others have had to evacuate repeatedly as the monster fires have scorched through more than 10.3 million hectares of land.

Authorities have warned that the summer fire season, spurred by high temperatures, strong winds and a three-year drought that has left bushland vulnerable, will continue until the country experiences solid rainfall.

The national weather agency confirmed fears there was no sign of that happening in the next few months as it released its annual report, which also showed that 2019 was Australia's hottest and driest year on record.

Many towns were without power and telecommunications and some were running low on drinking water supplies. 

"I listened to the advice that if you don't need to stay, then don't," said David Gatrell, 72, laying out a tent next to about 20 vehicles at a sports ground in Merimbula, a coastal town about 60 kilometers from his home at Towamba.

Parts of Kangaroo Island, a wildlife-rich tourist spot off the country's southeast coast where Prime Minister Scott Morrison on Wednesday made a plea for foreign tourists not to be deterred by the fires, were again evacuated on Thursday. A third of the island has already been destroyed by fires.
