Morning mail: Victoria reimposes restrictions, pressure on Craig Kelly, Myanmar unrest

Thursday: An Australian Open quarantine hotel worker tests positive to coronavirus. Plus: how a father-and-son team saved their home from bushfire

Good morning. Victorian premier Daniel Andrews assumes the worst" over latest Covid-19 positive infection, Perth's north-eastern edge remains on high bushfire alert, and all the fallout from the parliament corridor confrontation between Craig Kelly and Labor frontbencher Tanya Plibersek. That, and more, for your Thursday.

Mandatory Covid-19 mask rules have been reintroduced in Victoria after a 26-year-old worker at an Australian Open quarantine hotel tested positive to coronavirus. It has not yet been confirmed if the man has contracted the highly infectious UK strain of the virus, but the premier isn't taking any chances, tightening restrictions to levels in place at the start of January. The move has created scheduling chaos in the lead-up to the Australian Open, but Daniel Andrews maintained the event would still go ahead. Meanwhile, in contrast to the US or UK, a respected social survey has found Australia's response to Covid-19 has been marked by resilience and optimism, although Australians under 24 have responded less optimistically, with the research also suggesting the cohort is the worst-affected by the pandemic.
