The current outbreak of COVID-19 cases in Sydney has some close parallels to the second wave that hit Melbourne last year. Not only is the Sydney outbreak proving difficult to control, but it appears that public health messages are not reaching multicultural communities (CALD). This is particularly true where English proficiency is poor. This blog is essentially a Sydney version of one that I wrote last year about Melbourne. It looks at the main languages spoken in Sydney, highlighting those with poor English proficiency, and their spatial distribution in the metropolitan area.
