Morning mail: Sydney’s south-west on Covid alert, crisis in Haiti, Federer out of Wimbledon

Thursday: Renewed focus on vaccine rollout as NSW outbreak continues to grow. Plus: Haitian president assassinated in his home

Good morning. Covid concerns spread to western Sydney, Haiti is thrown into political crisis and Roger Federer's dream of a ninth Wimbledon title appears over. Those stories and more this Thursday, in Guardian Australia's morning mail.

Residents in Sydney's south-west are being urged to isolate amid the city's extended lockdown, with three local government areas - Liverpool, Fairfield and Bankstown-Canterbury - placed on high alert after 27 new cases. The NSW premier, Gladys Berejiklian, has told families: Do not leave the house," adding that the next nine or 10 days will determine how we live" until the end of the year. The state's chief health officer, Dr Kerry Chant, said the admission to hospital of eight people under 35 was a bit of a wake-up call to young people" but, as Josephine Tovey writes, younger Australian don't need a wake-up call, they need a functioning vaccine rollout that incorporates their age group.
