Queensland has recorded four local cases of the Alpha strain of Covid-19 just two days after the state emerged from lockdown. Premier Annastacia Palaszczuk told reporters at a press conference on Monday morning that all new cases are linked to a known cluster. The infections include a mother who works at a Greek community centre in Brisbane and her child, along with two close contacts of a man who travelled to Eumundi on the Sunshine Coast - his partner, and a colleague. Chief Health officer Dr Jeannette Young explained three of the four cases contracted the virus after they went to Zeus Street Greek Kitchen at Westfield Chermside, in the city's north.
