The evacuees were first sent to specially quarantined facilities at a remote airbase in Western Australia.

The Qantas 747 touched down last night (NZ time) at a Royal Australian Air Force base about 1200km north of Perth, carrying 243 passengers, 14 crew, four pilots and officials from the Department of Health.

Several children were on board, with 89 evacuees under 16 years of age, including five under the age of two.

The 747 could not land at the small Christmas Island airstrip, so the passengers will be transferred to two smaller planes to make the trip.

Blue gum trees - an important koala habitat - were harvested from the plantation in December, leaving only a few isolated stands of trees.

Some koalas had starved to death in the remaining trees. Others were apparently killed by bulldozers.

About 80 surviving koalas have been removed and are being cared for.

The deaths come after tens of thousands of koalas were killed in the bushfires that have ravaged Australia. The marsupial is listed as "vulnerable" by Australia's Environment Ministry.

Described as a "game changer" that will help scientists determine whether a future vaccine is effective, experts at Melbourne's Peter Doherty Institute for Infection and Immunity on Tuesday became the world's first scientific lab outside of China to recreate the virus.

They will now share it with the World Health Organisation (WHO) in Europe, which will in turn share it with labs worldwide — including one from Queensland — involved in the worldwide race to develop a vaccine.

The team of scientists grew the virus from a patient who had been infected since Friday.

There are currently 1,287 confirmed cases in China, 41 of whom have died.

It comes as China is begins celebrations of the Lunar New Year, one of the most important dates in its calendar.

Many events have been cancelled and a new hospital is being built in the city of Wuhan.

The virus has now spread to Europe, with three cases confirmed in France.

The first case was in Bordeaux, while the other two were in the Paris area, the French health minister said on Friday night.

And one case has been confirmed in Australia.

Australia's High Commissioner to PNG, Bruce Davis, said the initial deployment would assist the Australian military with its response.

PNG prime minister James Marape had earlier offered to send 1000 soldiers and firefighters.

Vanuatu has also come to Australia's aid, donating $US175,000 to the bushfire recovery effort.

On Thursday, Australian prime minister Scott Morrison thanked PNG, Vanuatu and Fiji for their support, calling it overwhelming.

Palau's president has also written to Mr Morrison to offer support.

The declaration, which gives the state and emergency services additional powers, was put into place last Thursday.

Mr Andrews said the extension was needed to manage what was likely to be a significant increase in bushfire activity over the next 48 hours.

The state of disaster covers East Gippsland, the Alpine region and the state's north-east.

Authorities are urging people to leave the Alpine region and all areas east of Bairnsdale, in East Gippsland, as the fire danger once again ramps up.

At least 24 people have died since the fires began in September. Air quality in the capital Canberra was this weekend rated the worst in the world.

Mr Morrison announced the creation of a recovery agency to help those who have lost homes and businesses in the fires.

He has faced fierce criticism over the speed of his response to the crisis.

The weekend saw some of the worst days of the crisis so far, with hundreds more properties destroyed. Rural towns and major cities saw red skies, falling ash and smoke that clogged the air.

New Zealand wilted in the Melbourne heat at the MCG, where Australia wrapped up a crushing 247-run win on day four of the second Test on Sunday.

Blundell rallied for the Black Caps, celebrating his second Test hundred in three matches with a resilient 121 runs, but he had no support from his team-mates after Nathan Lyon (4-81) and James Pattinson (3-35) starred.

Marnus Labuschagne (1-11) ended Blundell's unforgettable innings late in the evening as Australia only required nine wickets to skittle New Zealand for 240 – Trent Boult not batting due to a fractured finger.

The average temperature across the country was 40.9 degrees Celsius, breaking the mark of 40.3C set in January 2013, but it's a record unlikely to last for long.

Temperatures were well over 45C for much of the interior — the location record (50.7C at Oodnadatta) is still safe — but the wide spread of exceptional heat meant the national average record was broken.

The heat is expected to keep building over the next few days as the air mass moves across the country.

The current record of 50.7 degrees was set in January 1960 in the outback town of Oodnadatta in South Australia.

Temperatures have been high over the weekend in Western Australia.

Forecasters say the extreme heat is expected to affect the rest of the country in the coming week, with temperatures likely to exceed 40 degrees in many areas from Wednesday.

Australian firefighters are struggling with out of control bush fires as hot and dry weather continues.

Total fire bans are in place for parts of New South Wales with 100 bush fires currently burning.
