Morning mail: Melbourne cluster grows, Trump's message to insurrectionists, Crown resignations

Friday: Two more Covid cases linked to the Holiday Inn quarantine hotel. Plus: simple strategies to cope with bluebottles

Good morning - it's Imogen Dewey here with the latest news on Victoria's Covid-19 cluster, the impeachment trial, and what the Australian government is and isn't doing for the environment.

Melbourne's hotel quarantine cluster has risen to 13 as more close contacts test positive to Covid - and a pandemic survey has found Australians are more worried about money and less confident in the government. While Scott Morrison still says hotel quarantine is the right way to go", US health officials are advising that anyone who has received the full course of Covid vaccines can skip the standard 14-day lock-in. And in good news on that front, the Pfizer vaccine is showing a strong response to new Covid variants.
