Good morning. It’s Monday 26 April: a lockdown decision is due out of Perth, there’s new pressure on companies to act on climate, and conflict with China may still be on the table. (Plus, the Oscars are on later this morning.)

Western Australian premier Mark McGowan will decide this morning, local time, whether or not to extend a three-day snap lockdown for the Perth and Peele region after no new Covid cases were locally acquired yesterday – though he has said “people should get used to the prospect that there will be some further measures that continue”. He blamed the federal government for allowing too many Australians to travel overseas to attend “weddings” and “athletics meets” during the pandemic – pushing back after defence minister Peter Dutton earlier said McGowan’s government had made a “mistake” in using the hotel where the latest Covid-19 leak originated. While the man who contracted Covid in quarantine then boarded a flight to Melbourne (after five days in the community in Perth), Victoria has so far not recorded any new cases following testing of flight passengers.
