Victoria flattening curve despite deadliest day.

Premier Daniel Andrews is confident Victoria's COVID-19 curve is flattening despite cases returning above 400 on Australia's deadliest day of the pandemic.

While noting Victoria's seven-day case average was falling, Andrews acknowledged the lockdown's full effects would not be known until next week.

"We all know that a week is not the life-cycle of this virus," he told reporters yesterday.

"This is not precise. It's not exact because it's all dependent upon literally hundreds of millions of individual choices and decisions that each of us make every single day."


Victoria reported another 21 deaths and 410 new cases on Wednesday as tensions continued to simmer between state and federal governments over the hotel quarantine scheme.

Sixteen of those who succumbed to the virus in the 24 hours to Wednesday were in aged care.

Geelong (179 active cases), Bendigo (53) and Ballarat (22) are becoming an increasing concern to the state government despite their infection rates remaining relatively stable.

Concern in NSW over unknown virus sources.

There is concern among the NSW premier and health authorities about the increase in COVID-19 cases across the state with no known source.

Premier Gladys Berejiklian flagged NSW needs to go further in preventing the spread of the virus which includes wearing masks where social distancing cannot be guaranteed on public transport, at religious services and in supermarkets.


Ms Berejiklian also admitted her concerns around the "cumulative accumulation of those unknown sources".

NSW recorded 18 new COVID-19 cases in the 24 hours to 8pm on Tuesday with two linked to Cherrybrook's Tangara School for Girls.

Thirteen of the cases were locally acquired and linked to known cases, one was a returned traveller from overseas, two were locally acquired without a known source, and two were acquired in Victoria.

NZ COVID cases might have come in via freight.

Biden and Harris hold first campaign event. 

Democratic presidential candidate Joe Biden is holding his first campaign event with Kamala Harris, a day after unveiling her as his running mate.

At a high school in Mr Biden's home state of Delaware, he said "this is a serious moment for our nation" ahead of November's election.


Harris, a California senator, is the first Black woman and South Asian American to serve in the role.

"This morning, little girls woke up across this nation — especially Black and Brown girls who so often may feel overlooked and undervalued in our society — potentially seeing themselves in a new way: As the stuff of Presidents and Vice Presidents," Biden wrote on Twitter.

Harris wrote: "Joe Biden - I'm ready to get to work."

2019 hottest year, ending warmest decade.

The past decade was the world's hottest since records began in the Industrial Revolution, a new report has warned.

Last year was one of the three hottest years since the 1800s, only outstripped by 2016, and 2015 in some analyses, the 30th edition of the Bulletin Of The American Meteorological Society said.

The data for last year showed the global climate was continuing to change rapidly, with consequences from melting glaciers to exceptional wildfires.


The peer-reviewed State Of The Climate report said 2019 saw out the warmest decade on record, and that each decade since 1980 had been successively warmer than the one before.

The last decade, 2010-2019, was 0.2C warmer than the previous 10 years from 2000-2009.
