Melbourne will become the most locked down city in the world tomorrow night, beating Buenos Aires in Argentina at 245 days in lockdown as the state of Victoria announced 1220 new cases of Covid-19 and three deaths.

The new cases were detected from 71,275 test results, marking a second straight record day of testing.

They bring the state's total number of active cases to 11,785.

Yesterday the state announced 1488 new cases - its highest total since the Covid-19 pandemic began.

A total of 36,248 vaccine doses were administered at state-run sites yesterday.

More than 81 percent of Victorians have now had a single dose of a Covid-19 vaccine, while over 51 percent have been fully vaccinated.

Cases drop dramatically in three weeks in NSW

New South Wales has recorded a "dramatic drop" in community cases, with 667 infections and 10 deaths as the state announced an easing of self-quarantine rules for the fully vaccinated.

The cases recorded in the latest reporting period were the lowest since 19 August.

"It's quite a dramatic drop," Health Minister Brad Hazzard said.

"All the hard work that we have done ... to have gone from 1599 cases just three weeks ago to 667 cases today has taken a lot of hard work.

"Please don't ruin that, please don't let this side down. This is a game that we all must win."

Self-quarantine rules for people who have been in close contact with a positive case are being relaxed from 11 October.

Any close contact who is vaccinated will only be required to get tested and self-isolate for seven days, instead of 14.

If a person tests positive they will have to self-isolate for 14 days, regardless of their vaccination status.

Hazzard said 66.5 percent of the state's population aged 16 and over was now fully vaccinated, and 88.1 percent had received their first dose.

He expects the state to hit its 70 percent milestone in the middle of the week.
