More than six million Victorians are living under stay-at-home orders for the fifth time since the start of the pandemic, due to a growing outbreak of the COVID-19 Delta variant.

The rules applied during last month's lockdown have been reimposed, including a 5km travel limit for exercise and shopping and compulsory mask-wearing indoors and outdoors.

"We've got no choice. We don't want this getting away from us and being locked down for months," Mr Andrews said.

Late on Thursday, the federal government announced the COVID-19 Disaster Payment scheme would be available to people who work or live in Greater Melbourne, as well as the local government areas of Moorabool Shire, the City of Greater Geelong, Borough of Queenscliff and the Surf Coast Shire.

City of Ballarat was not included in that list, but it is believed the state government will shoulder that cost.

People who have lost at least 20 hours a week will get $600 while those who have lost between eight and 20 will receive $375.

No liquid assets test will be applied to the payments.

The Victorian government will provide "significant additional economic support to businesses".

Mr Andrews has warned there is no guarantee the lockdown will end as planned at 11.59pm on Tuesday.

"It may be longer because it depends on what every Victorian does," Mr Andrews said.

However, he flagged restrictions in regional Victoria could be lifted earlier if it is safe to do so.

It came after Victoria recorded two additional locally acquired COVID-19 cases on Thursday afternoon, taking the number of community cases linked to the outbreak, which originated in NSW in mid-June, to 18.

Most of the cases are connected to NSW removalists who breached their worker permit conditions and spread the virus during a drop-off at the Ariele Apartments in Maribyrnong late last week.
