Good morning. Coronavirus continues to dominate local and international headlines, as Victoria contemplates strict measures once again, and US intelligence probes the pandemic's origins.

Victoria appears set to re-enter lockdown, with leading ministers from the state government to meet this morning to discuss its response, as the Melbourne Covid-19 cluster grows to at least 15. As the outbreak prompts a surge in Victorians getting vaccinated, the Australian Medical Association has called for any Australian approved for overseas travel to be forced to have a vaccine, in a bid to reduce the threat from Covid and to incentivise vaccination. The federal cabinet approved the fast-tracking of vaccines for Australians given permission for travel earlier this month, but on a voluntary basis. More than 144,000 Australians have been given permission to leave since the pandemic begun, but around 40,000 remain stranded overseas due to caps on quarantine places.
