This evening there's an anxious wait in Adelaide....where there's mass testing to determine just how far a coronavirus cluster has spread, with the chief health officer saying 4000 people are considered close contacts of the positive cases and have been advised to self-isolate.

Also:

* It's the country's most populous state and today .. the plan to rescue New South Wales from the COVID-19 recession .. and perhaps help drive the national recovery .. has been unveiled.

* Will the big spend on social housing detailed in the NSW budget help drive recovery?

* The Prime Minister makes his first foreign trip during the pandemic - to Japan - it'll mean two weeks of self-isolation on return - so why the urgency? We hear from Emeritus Professor Rikki Kersten, Japan expert at Murdoch University.

* Opposition leader Anthony Albanese has dismissed a mysterious online dossier containing allegations of bullying in his office as a "fake".

* Federal government plans to entrench and extend the cashless welfare card have been endorsed by a Coalition dominated Senate committee, despite a swathe of submissions and evidence against it.

* And...can the COVID crisis actually help us get better at preparing for climate-related disasters? We speak to one of the authors of the Red Cross's World Disasters Report Maarten van Aalst, who’s also a coordinating lead author on the IPCC.
