Here’s a link to Guardian that should work.
In short, on Wednesday a man was identified as having covid and had puttered around Sydney visiting a bunch of barbecue shops among other things. His wife has also since tested positive. He had no obvious link to the genetically linked covid case who was a new arrival in hotel quarantine. Concerning, as we only have covid in new arrivals [~110 at the moment] and all are in hotel quarantine and we’d like to keep it that way.
Because there is a missing link between the overseas arrival and the man, there is assumed to be at least one positive person unidentified in the chain. We’ve been in extended restrictions [masks indoors, 20 people at private gatherings etc] for three days and a testing blitz but no further cases. These eased back but not entirely lifted for another week.
