Australia's Victoria state authorities said plans to ease Covid-19 restrictions in state capital, Melbourne, this week remained “on track” as new locally acquired coronavirus cases fell.

Two new locally acquired cases, both linked to existing clusters, were reported, down from 11 a day earlier, according to Reuters.

“While we never want to see new cases, it is reassuring that we are again seeing these cases with clear links to existing outbreaks,” Victoria state Acting Premier James Merlino told reporters in Melbourne.

Merlino said contact tracers have linked the source of the highly infectious Delta virus variant to an overseas traveller who entered hotel quarantine in Melbourne on May 8.
