The decision to thrust Greater Sydney and surrounding regions into lockdown was “inevitable” as New South Wales' contact tracers were being “outrun” by COVID-19, says Australian Medical Association’s Vice President Chris Moy. Greater Sydney, the Blue Mountains, Wollongong and the Central Coast will be subject to stay-at-home orders for two weeks from 6pm on Saturday after recording 29 new local cases overnight. “This decision was inevitable – they (health authorities) were unanimous that this had to happen,” Dr Moy told Sky News. “What we’re dealing with is the Delta variant and this strain is quite a different beast to anything we’ve seen before. “The contact tracers have clearly been overwhelmed and this thing is outrunning them.”
