Trump calls governors “weak” and a “bunch of jerks” as US protests continue.

US President Donald Trump has called state governors “weak”, as he urges them to crack down on protests over racial inequality on the seventh night of looting and vandalism.

“You’ve got to arrest people, you have to track people, you have to put them in jail for 10 years and you’ll never see this stuff again,” Trump reportedly said in a video conference with national security officials and top police, according to Insider.

“You have to dominate,” he told the governors. “If you don’t dominate, you’re wasting your time – they’re going to run over you, you’re going to look like a bunch of jerks.”

Trump said the federal government was going to clamp down “very strong” on the violence.

“These were the people that trashed Seattle years ago. Who’s paying for these people. I was appalled that 13 of Joe Biden’s staff were donating money to bail people out in Minneapolis. They should have stayed in jail until this is over (and beyond).” @newtgingrich @foxandfriends

Dozens of cities across the United States remain under curfews, at a level not seen since riots following the 1968 assassination of civil rights activist Martin Luther King Jr.

The National Guard has been deployed in 23 states and Washington DC.

One person has been killed in Louisville, Kentucky, overnight where police and National Guard troops returned fire while trying to disperse a crowd.

1. The protests represent a genuine and legitimate frustration over a decades-long failure to reform police practices and the broader criminal justice system. We should condemn the few who resort to violence––not the overwhelming majority who deserve our respect and support.

The unrest, which erupted as the country was easing lengthy lockdowns to stop the spread of the coronavirus, began with peaceful protests over the death of a black man, George Floyd, in police custody in Minneapolis last Monday.

Video footage showed a white police officer kneeling on the neck of Floyd, 46, for nearly nine minutes before he died.

Derek Chauvin, a since-fired 44-year-old police officer, has been charged with third-degree murder and second-degree manslaughter.

Trump has condemned the killing of Floyd and promised justice, but has made no major public statement to address the crisis. In tweets, he has described violent protesters as “thugs” and threatened to use the US military.

The brother of George Floyd did receive a phone call from Trump, which he says “lasted probably two minutes. The conversation was okay”.

He is calling for protesters to stop the violence and “do this another way”.

“If I’m not over here messing up my community, then what are you all doing? … You all are doing nothing, because that’s not going to bring my brother back.”

Australia’s ‘youngest COVID-19 death’ tests negative.

The Queensland man thought to be Australia’s youngest COVID-19 victim has tested negative to the virus after his death.

Nathan Turner’s death last week had baffled authorities, and placed residents in his central Queensland town of Blackwater on notice, after an initial coronavirus test following his death returned a positive result.

But a workmate of Mr Turner’s fiancee on Monday revealed a second test conducted after his death came back negative.

"We have just got word from our staff member Nathan's partner that his autopsy report has come in and Nathan has been CLEARED as COVID 19 NEGATIVE.," Kelly Bunyoung posted on Facebook.

"Blackwater can now rest easy."

Queensland Health later confirmed the negative test.

"The Coroner tonight advised that further tests have returned negative for COVID-19. He is yet to determine the man's cause of death," the state's chief health office Jeannette Young said in a statement.

Mr Turner, 30, had serious underlying health issues before experiencing coronavirus symptoms in the weeks before he died and was not tested while alive.

Three new cases in NSW as restrictions dramatically ease.

NSW reported three new cases from more than 5700 tests on Monday, as pubs and restaurants reopened for 50 guests at a time. The new cases are all returned travellers in hotel quarantine.

The loosening of restrictions comes in time for the June long weekend with libraries, art galleries, museums, zoos, reptile parks and aquariums also reopening from Monday.

Queensland, Victoria, South Australia, and WA all significantly loosened restrictions on the first day of winter.

Australia needs more aerial firefighting capabilities for future bushfires.

Australia will need enhanced aerial firefighting capabilities in the future as it faces extended bushfire seasons, experts say.

A bushfires royal commission hearing is due to resume today, with a focus on aerial firefighting capabilities.

The national council for fire and emergency services says demand for aerial firefighting resources is likely to continue to increase.

In a submission to a separate Senate bushfires inquiry, the Australasian Fire and Emergency Service Authorities Council said firefighters were likely to face extended, hotter fire seasons in the future with more days of extreme fire danger.

"There is an imperative to continue to develop the current national collaborative arrangements to ensure efficient use of resources and to provide reliable access to surge capacity," AFAC said.

In a report for the royal commission, the Australian Transport Safety Bureau noted aerial firefighting activity during 2019-20 was around four times that of other recent bushfire seasons.

Victoria's coldest June start since 1943.

Melbourne recorded its lowest maximum June 1 temperature since 1943, reaching a top of just 11.2C on Monday.

Much of the state was lashed with strong winds, particularly in Port Phillip Bay where St Kilda copped wind gusts of up to 83km/h.

Winter has hit with a bang! #Melbourne only reached 11.2°C (the lowest max for the start of (calendar) winter since 1943). Mildura felt even colder, despite the sun! East Gippsland was the exception, Orbost reached a toasty 17°C. pic.twitter.com/Q62LJRdk4j
