A serious concern since the emergence of Covid-19 has been whether those who have had it can get it a second time – and what that means for exiting this crisis.

Those less convinced in Australia cast doubt on source of Wuhan lab ‘intelligence’. Plus: Trump and Jennifer Hawkins

The origin of the coronavirus has opened up a new battlefield between the Murdoch press and just about everyone else – and given the Daily Telegraph’s Sharri Markson an international platform on Rupert Murdoch’s Fox News.

Following in the footsteps of her colleague Miranda Devine, who also made it onto Fox News, Markson told Tucker Carlson Tonight the “bombshell dossier” she had uncovered showed some of the world’s foremost intelligence agencies were investigating whether the virus was linked to a lab in Wuhan.

In liberal democracies, the integrity, impartiality and professionalism of intelligence agencies matters. That’s why it is essential that intelligence agencies remain aloof, not only from the political debates of the day, but also from the policy decisions that individual governments may take. The intelligence community’s core task is to provide brutally realistic analysis on the threat environments we face so that governments can then make the best-informed policy decisions possible to preserve our common security.

The failures of the intelligence community before the Iraq war, the gullibility of much of the western media, as well as the cynical manipulation of both by the political class of the day, provide us with a stark reminder of what can go radically wrong. On 8 September 2002 the New York Times published one of this century’s most consequential news articles. The front-page story, supplied by the Bush administration, claimed that Saddam Hussein had stepped up his quest for weapons of mass destruction by acquiring key components for a nuclear weapon. In the UK, the Blair government’s “dodgy dossier” compounded the error. John Howard did the same in Australia. The problem was that it just wasn’t true. These were over-egged stories designed to soften the public up for what would become a disastrous war.

The app will ask for your name (or pseudonym), age range, postcode and phone number. Scott Morrison says the Australian government’s covid safe tracking app won’t be mandatory to download and install, but its uptake numbers could play a part in easing Covid-19 restrictions

The Australian government has launched Covidsafe, an app that traces every person running the app who has been in contact with someone else using the app who has tested positive for coronavirus in the previous few weeks, in a bid to automate coronavirus contact tracing, and allow the easing of restrictions.

Here’s what we know about the app so far.

Is Australia flattening the curve? We bring together all the latest Covid-19 confirmed cases, maps, stats and graphs from NSW, Victoria, Queensland, SA, WA, Tasmania, ACT and NT to get a broad picture of the Australian outbreak and track the impact of government response.

Due to the difference in reporting times between states, territories and the federal government, it can be difficult to get a current picture of how many confirmed cases of coronavirus there are in Australia.

Here, we’ve brought together all the figures in one place, along with comparisons with other countries.

When the coronavirus crisis hit, Yolngu elders moved back to east Arnhem Land homelands where they found freedom, peace, and power

Adapting to change is something Yolngu are good at, senior Rirratjingu songman Witiyana Marika says.

When the coronavirus first started making news, community leadership met to plan how they would manage if Covid-19 arrived in eastern Arnhem land. Senior men and women met with the emergency taskforce, the local Miwatj health service and the Laynhapuy homelands organisation to take the most vulnerable people further away from risk.

They’ve faced drought, extreme heat and bushfires, and now they have to deal with a new paranoia courtesy of the pandemic

Australia’s bats are turning up in increasing numbers in city suburbs. But as they search for food, they’re bringing for some a newfound paranoia thanks to a global pandemic that likely sprang from one of their overseas relatives.

In Ingham in far north Queensland, an influx of more than 200,000 little red flying foxes in January was variously described as a “swarm”, a “tornado” and an “infestation”.

As the US deals with a Covid-19 catastrophe in its meatworks, the Melbourne factory points to the potential for outbreaks in Australia

Working in an abattoir at the best of times is tough. The hours are long, the labour is intensive and, for rank and file labourers, the pay is low.

Now, in the Covid-19 crisis, workers have one more thing to worry about – around the world their factories have proved to be a hotbed of infection. As Australia moves to ease lockdown laws, meat workers may still be at the frontline of exposure and infection.

The millions of unemployed in Thailand due to the coronavirus include elephants dependent on tourists to feed their voracious appetites. With scant numbers of foreign visitors, commercial elephant camps and sanctuaries lack funds for their upkeep and have sent more than 100 of the animals trudging back to their natural habitats.

Scientists are cautioning that it’s still too early to know how the novel coronavirus mutates after a preliminary study in the U.S. claimed that a new strain of the virus has emerged that is more dominant and contagious than the original.

What may be the latest hope in the hunt to develop a treatment for COVID-19 comes from an unusual source – a furry, four-year-old llama named 'Winter' that is living on a farm in the Belgium countryside.
